Heald frame with a reinforcement profile.
[0001] The invention relates to a heald frame with a
reinforcement profile, to a transverse element for such
a heald frame, to a weaving machine with such a heald
frame and to a method for producing such a heald frame.
[0002] It is known to provide a heald frame with a top
transverse element and a bottom transverse element
which are connected to side elements in order to form a
heald frame. In the following description and claims
the top transverse element and the bottom transverse
element are referred to as transverse elements.
[0003] In order to allow high-speed weaving, heald
frames should be as light and rigid as possible. It is
known in the prior art to provide heald frames made of
a light material such as aluminum, an aluminum alloy or
a composite material. In order to ensure a sufficient
rigidity, it is known to provide a reinforcement
profile, which is fastened to the heald frame.
[0004] Healds are provided on the heald frame with
considerable play or clearance in order to allow a
weaver to move the healds. As a result, the healds also
move during a weaving process. In order to counteract
the wear caused by the sliding movement of the healds,
it is known to provide heald carrier profiles which are
fastened to the transverse elements. Preferably, the
heald carrier profiles are made of a wear-resistant
material such as steel or a similar material.
[0005] Heald frames with one or more reinforcement
profiles are described, for example, in
EP 1 516 948 Al, US 4,633,916, US 3,754,577,
WO 2008/040559 Al, WO 2011/023383 Al, JP 2006-138040 A ,
EP 1 528 130 A2 and EP 0 457 210 A l . From these
documents it is known, for example, to provide carbon
fiber, carbon fiber reinforced or other fiber
reinforced reinforcement profiles.
[0006] It is an object of the invention to provide an
improved heald frame with a high rigidity in order to
allow high-speed weaving and/or weaving with heald
frames having relatively large dimensions in lengthwise
direction, which heald frame is easily produced or
manufactured. It is further an object of the invention
to provide a weaving machine with such a heald frame
and a method for producing such a heald frame.
[0007] This object is solved by a heald frame
according to claim 1 and a transverse element according
to claim 9 .
[0008] A heald frame according to the invention
comprises a transverse element with a hollow profile
member with at least one cavity and a reinforcement
profile which is inserted in the at least one cavity,
wherein the at least one cavity is provided with a
receiving section extending over at least a part of the
length of the transverse element and adapted for
receiving the reinforcement profile when the
reinforcement profile is axially displaced in the
lengthwise direction of the transverse element and is
in a first angular position relative to the transverse
element, and wherein fastening means are provided for
fastening the reinforcement profile in the receiving
section of the transverse element, in which a fastening
by the fastening means is achieved by relative rotation
of the reinforcement profile and the receiving section
of the transverse element.
[0009] In the context of the application, a relative
rotation of the reinforcement profile and the receiving
section of the transverse element is defined as a
relative rotational displacement between the
reinforcement profile and the receiving section of the
transverse element, wherein both elements can rotate in
opposite directions, both elements can rotate in the
same direction with a different rotation angle, or only
one element, preferably the reinforcement profile, can
be rotated with respect to the second element,
preferably the receiving section of the transverse
element .
[0010] The reinforcement profile can easily be
inserted into the receiving section from a side end of
the transverse element, also named insertion entry, in
particular while the reinforcement profile is in a
first angular position relative to the transverse
element, also named first angular orientation. In one
embodiment, the length of the reinforcement profile
extends over a limited part of the length of the
transverse element. In preferred embodiments, the
reinforcement profile extends over the entire length of
the transverse profile. The reinforcement profile and
the receiving section are preferably formed in order to
make at least an easy insertion possible when both are
aligned in the first angular position. The fastening
is achieved when rotating the reinforcement profile
with respect to the receiving section for fastening the
reinforcement profile inside the transverse element.
[0011] In preferred embodiments, glue is provided as
fastening means, wherein the glue is spread by rotation
of the reinforcement profile relative to the receiving
section. Using glue, also named adhesive, as a
fastening means allows an easy and secure fastening
without clearance after fastening by the glue. The
type of glue is for example adapted to the material,
which is used for the reinforcement profile and/or for
the receiving section. In order to improve the
fastening of a reinforcement profile in the transverse
element, undulating surfaces may be provided,
preferably on the reinforcement profile, similar to the
ones that are for example described in
WO 2008/040559 Al, the content of which is hereby fully
incorporated in the application.
[0012] In preferred embodiments, the receiving section
has an opening adapted for letting pass or guiding the
fastening means while the reinforcement profile is in
the first angular position relative to the transverse
element. The opening allows the fastening means to be
guided or let pass during the relative movement in
lengthwise direction and/or to prevent that the
fastening is achieved well before a desired positioning
in lengthwise direction of the reinforcement profile is
attained. In preferred embodiments, glue is spread
over a limited area of the outer surface of the
reinforcement profile, whereby the width of the limited
area corresponds to the width of the opening. The
opening is realized in one embodiment by providing a
gap in the contour of the receiving section. In other
embodiments, the opening is provided by forming a bulge
on the contour of the receiving section.
[0013] In preferred embodiments, the reinforcement
profile has an elongated cylindrical shape with a
rotationally symmetric cross-section or an essentially
rotationally symmetric cross-section. The reinforcement
profile in one embodiment is in the shape of a circular
cylinder with a hollow or solid profile. This allows
an easy producing and an easy handling when inserting
or rotating the reinforcement profile for achieving the
fastening, for example for spreading the glue. The
outer surface in one embodiment is undulated in the
lengthwise direction and/or the cross-section for
increasing the effective bonding surface. In other
embodiments, the surface is roughened for improving the
bonding effect. Such outer surfaces are referred to as
essentially rotationally symmetric in the context of
the application.
[0014] The contour of the receiving section is adapted
to the outer shape of the reinforcement profile for
allowing a relative movement in lengthwise direction,
at least while the reinforcement profile is in the
first angular position relative to the transverse
element. In preferred embodiments, the receiving
section has a rotationally symmetric cross-section or
an essentially rotationally symmetric cross-section in
the cross-direction of the transverse element. When
the receiving section and the reinforcement profile are
both provided with a rotationally symmetric or
essentially rotationally symmetric cross-section, a
relative movement in lengthwise direction is possible
in any angular position. Therefore, a producing of the
heald frame is facilitated. In preferred embodiments,
the cavity has a closed cross-section in the crossdirection
of the transverse element in order to make
possible a rigid structure of the transverse element.
[0015] According to a preferred embodiment, the heald
frame comprises a top and a bottom transverse element,
which are connected with the aid of two side elements.
The sides of the top and of the bottom transverse
element facing each other are referred to as the inner
sides of the transverse elements. The sides of the top
and of the bottom transverse element that are arranged
at an outer side of the heald frame, are referred to as
the outer sides of the transverse elements. On the top
transverse element, the inner side corresponds to the
under side of the transverse element, while the outer
side corresponds to the upper side of the transverse
element. On the bottom transverse element, the inner
side of the transverse element corresponds to the upper
side of the transverse element, while the outer side
corresponds to the under side of the transverse
element .
[0016] In preferred embodiments, the cavity is further
provided with a hollow section, wherein the receiving
section and the hollow section are positioned stacked
in the height of the transverse element and are
connected via an opening, in other words an opening is
formed between the hollow section and the receiving
section. This allows a rigid structure of the
transverse element. Preferably, the receiving section
and the hollow section are stacked in the height so
that the receiving section is closer to the inner side
of the transverse element than the hollow section in
order to allow a higher rigidity in the region, in
which forces are introduced.
[0017] In one embodiment, the hollow profile member is
provided with a number of cavities, wherein at least
one cavity, in particular a cavity closest to the inner
side of the transverse element, is provided with a
receiving section. Providing a reinforcement profile
close to the inner side allows for a rigid structure in
the region in which forces are introduced to the heald
frame .
[0018] According to a preferred embodiment, the
reinforcement profile is a carbon fiber or a carbon
fiber reinforced reinforcement profile.
[0019] According to preferred embodiments, the
transverse elements are made of a lightweight material
such as aluminum, an aluminum alloy or a composite
material. If a heald carrier profile is available, the
heald carrier profile and the transverse element are
preferably made of a different material in order to
produce a lightweight heald frame with a sufficient
wear resistance on the heald carrier profile. The heald
carrier profile is preferably made of a wear-resistant
material such as steel.
[0020] According to an embodiment, the transverse
element is formed utilizing metal forming techniques.
Alternatively, shaping techniques, such as rolling or
extruding, can be used to shape the transverse element.
[0021] In preferred embodiments, the heald frame
further comprises a heald carrier profile to hold the
healds, which heald carrier profile is fastened to the
transverse element. In preferred embodiments, the heald
carrier profile is fastened to the transverse element
using an adhesive or glue.
[0022] In addition, the object is solved by a
transverse element for a heald frame with a hollow
profile member with at least one cavity, wherein the at
least one cavity is provided with a receiving section
extending over at least a part of the length of the
transverse element and which is adapted for receiving a
reinforcement profile, which reinforcement profile is
axially displaceable in the lengthwise direction of the
transverse element when the reinforcement profile is in
a first angular position relative to the transverse
element, and wherein the receiving section has an
opening adapted for letting pass or guiding the
fastening means while the reinforcement profile is in
the first angular position relative to the transverse
element .
[0023] This object is further solved by a weaving
machine according to claim 10, more in particular a
weaving machine provided with a heald frame according
to claim 1.
[0024] Further, the object is solved by a method
according to claim 11.
[0025] According to the invention, the reinforcement
profile is inserted from an insertion entry at a side
end of the transverse element into a receiving section
of the cavity extending over at least a part of the
length of the transverse element by a relative movement
of the reinforcement profile and the transverse element
in the lengthwise direction of the transverse element
with a fixed first angular orientation and the
reinforcement profile is fastened to the transverse
element by a relative rotation of the reinforcement
element and the receiving section of the transverse
element .
[0026] In preferred embodiments, the fastening is
achieved by the fastening means when rotating the
reinforcement profile relative to the receiving
section. In order to allow the insertion of the
reinforcement profile with fastening means in the
receiving section, in preferred embodiments, the
receiving section is provided with an opening extending
over at least a part of the length of the transverse
element, wherein the fastening means are provided,
which fastening means are guided or passed through the
opening upon the insertion of the reinforcement profile
into the receiving section.
[0027] In preferred embodiments, glue is applied on at
least an area of the reinforcement profile. In
preferred embodiments the glue is applied while the
reinforcement profile is inserted into the receiving
section .
[0028] Preferably, the glue is applied on a limited
area of the surface of the reinforcement profile, which
glue is spread over the receiving section by rotation
of the reinforcement profile relative to the receiving
section. The reinforcement profile is oriented with
respect to the receiving section so that the area with
glue applied is aligned with the opening of the
receiving section. Hence, the glue is guided or allowed
to pass via the opening, while the reinforcement
profile is moved in lengthwise direction. At the end of
the insertion of the reinforcement profile, the
reinforcement profile and the transverse element are
relatively rotated so that the glue is spread over the
contour of the reinforcement profile and/or the
receiving section. Thereafter, the glue fastens the
two elements.
[0029] In another preferred embodiment, glue is
applied to at least one end region of the receiving
section, in particular to the end region opposite to
the insertion entry at which the reinforcement profile
is inserted. Preferably, the reinforcement profile is
not fully inserted when rotating the reinforcement
profile for achieving the fastening. Therefore, no glue
is supplied to the end region opposite the insertion
entry via the reinforcement profile. By supplying
additional glue to the end region of the receiving
section opposite the insertion entry, a fastening in
this region is also ensured when the reinforcement
profile will be fully inserted in the receiving
section .
[0030] Embodiments of the invention will be described

[0039] figure 9 a further variant embodiment similar
to figure 3 .
[0040] Figure 1 is a schematic view of a heald frame 1
which comprises two transverse elements 2 , namely a
bottom transverse element 2 and a top transverse
element 2 . A heald carrier profile 3 is fastened to
each of the transverse elements 2 . Healds 4 are
arranged to the heald carrier profiles 3 . The
transverse elements 2 are connected to side elements 5 .
The sides of the transverse elements 2 facing each
other are referred to as the inner sides 11. The sides
opposite to the inner sides 11 are referred to as the
outer sides 12.
[0041] Figure 2 shows a perspective view of the top
transverse element 2 of the heald frame 1. The heald
carrier profile 3 is fastened to the front of the
transverse element 2 at the inner side 11 of the
transverse element 2 . The heald carrier profile 3 is
fastened to the transverse element 2 by glue 6 . In the
example of figure 2 , the heald carrier profile 3 has a
C-shape .
[0042] In order to improve the rigidity of the
transverse element 2 , in the embodiment shown a carbon
fiber reinforcement profile 7 is arranged at an outer
side 12 of the transverse element 2 , for example as
known from WO 2008/040559 A l . In addition, in the
embodiment shown a synthetic damping strip 8 facing the
heald carrier profile 3 is arranged on the transverse
element 2 , for example as known from EP 1240371 B l .
[0043] The depicted transverse element 2 comprises an
elongate hollow profile member 2 1 and a slat 22 which
are integrally formed. The slat 22 comprises a collar
23 to which the heald carrier profile 3 is fastened.
The elongate hollow profile member 2 1 and the slat 22
are for example made of aluminum, an aluminum alloy or
a composite material in order to obtain a lightweight
transverse element 2 . In order to further reduce the
weight of the transverse element 2 , the elongate hollow
profile member 2 1 is provided with a number of cavities
24, 25, 26 and 27.
[0044] According to the invention, a reinforcement
profile 10 is arranged inside the transverse element 2 ,
more in particular inside the cavity 27 closest to the
inner side 11. The cavity 27 is provided with a
receiving section 9 adapted for receiving a
reinforcement profile 10 which is axially displaceable
in the lengthwise direction of the transverse element
2 . The depicted reinforcement profile 10 has an
elongated cylindrical shape with a round, this means
circular cross-section. The reinforcement profile 10
is fastened to the transverse element 2 by means of
glue. The depicted reinforcement profile 10 has a
relative smooth surface. In other embodiments, the
reinforcement profile 10 has an undulating surface or a
certain roughness in order to improve a secure
fastening by glue. The reinforcement profile 10 is
preferably a carbon fiber reinforcement profile.
[0045] As can be understood from figure 3 , the
receiving section 9 has an essentially rotationally
symmetric cross-section in the cross-direction of the
transverse element 2 . The cavity 27 is further
provided with a hollow section 13. The receiving
section 9 and the hollow section 13 are positioned
stacked in the height of the transverse element 2 and
are connected via an opening 14, for example formed as
a gap. Preferably, the receiving section 9 and the
hollow section 13 are stacked in the height so that the
receiving section 9 is closer to the inner side 11 of
the transverse element than the hollow section 13.
[0046] In figure 4 a transverse element 2 with a
receiving section 9 for a reinforcement profile 10 and
the reinforcement profile 10 are shown before the
reinforcement profile 10 is inserted in the receiving
section 9 of the transverse element 2 . By means of a
supply unit 15 for glue 16, glue 16 is provided on top
of the reinforcement profile 10, while the
reinforcement profile 10 is moved axially with respect
to the transverse element 2 , while keeping the
reinforcement profile 10 in a first angular position
relative to the receiving section 9 . In other words,
the reinforcement profile 10 is moved in lengthwise
direction A of the transverse element 2 without
rotating the reinforcement profile 10 relative to the
transverse element 2 . The glue 16 is supplied to an
area 2 0 of the reinforcement profile 10 which can pass
along the opening 14.
[0047] According to an embodiment the glue 16 is
supplied by means a of supply unit 15 on top of the
reinforcement profile 10 at the height of the insertion
entry 18, more particularly at the height of the hollow
section 13 near the side end 19 of the transverse
profile 2 . This allows to apply the glue 16 on the
reinforcement profile 10 so that the glue 16 is guided
or can pass surely via the opening 14 while the
reinforcement profile 10 is inserted in the receiving
section 9 . This allows also to apply only glue 16 after
the reinforcement profile 10 is inserted over a small
distance in the receiving section 9 .
[0048] When the reinforcement profile 10 is almost
fully inserted in the transverse element 2 , as depicted
in figures 5 and 6 , the reinforcement profile 10 is
rotated, for example in direction R , in the receiving
section 9 so that the glue 16 is spread along the
reinforcement profile 10 and/or the receiving section 9
for fastening the reinforcement profile 10 to the
transverse element 2 , as depicted in figure 7 .
[0049] In order to improve the glueing, glue 16 can be
applied near the end regions of the receiving section 9
before the reinforcement profile 10 is inserted. This
is advantageous for applying glue 16 at the end region
17 of the receiving section 9 opposite to the insertion
entry 18 at a side end 19 of the transverse element 2
because for allowing a manipulation of the
reinforcement profile 10, the reinforcement profile 10
may not be fully inserted in the receiving section 9
during rotating the reinforcement profile 10 before
spreading the glue.
[0050] Figure 8 shows an embodiment comparable to
figure 3 , wherein a transverse element 2 is only
reinforced with a reinforcement profile 10 according to
the invention that is fastened inside the transverse
element 2 , in particular in the receiving section 9 of
the cavity 27 that is situated in the vicinity of the
heald carrier profile 3 . The reinforcement profile 10
as depicted in figure 6 is a hollow reinforcement
profile, for example tube shaped. In figure 8 the heald
carrier profile 3 has a J-shape.
[0051] Figure 9 shows an embodiment comparable to
figure 3 , wherein a reinforcement profile 10 with an
undulating surface is provided that is arranged near
the inner side 11.
[0052] It is clear that a suitable glue can be chosen
for the glue 6 applied for fastening the heald carrier
profile 3 and the glue 16 applied for fastening the
reinforcement profile 10. The glue 16 applied for
fastening the reinforcement profile 10 can be chosen in
order to fasten the reinforcement profile 10 inside the
receiving section 9 at the height of the cavity 27 of
the transverse element 2 , while the glue 6 applied for
fastening the heald carrier profile 3 can be chosen in
order to connect the heald carrier profile 3 to the
slat 22 of the transverse element 2 taking into account
different material mating.
[0053] In another non-depicted embodiment, a
transverse element 2 is provided, wherein only a top
reinforcement profile 7 and no reinforcement profile 10
according to the invention is arranged to the
transverse element 2 . Such a transverse element 2 may
be provided with a receiving section 9 according to the
invention allowing a suitable preparation for inserting
a reinforcement profile 10 only when required. Hence,
it is clear that a transverse element 2 with a
respective receiving section 9 is suitable for applying
the invention by inserting a reinforcement profile 10.
[0054] The fastening means can be of any kind in order
to allow a fastening by form locking, force locking or
material locking of the reinforcement profile inside
the transverse element. In one embodiment, the
fastening means are provided in the form of a springloaded
clamp for providing a force locking. In other
embodiments, a form-locking is attained using click
connections. In one embodiment the fastening means are
provided as separate means or for example elements
provided between the elements to be fastened. In other
embodiments, the fastening means are formed integrally
with the reinforcement profile or with the receiving
section, for example to allow an interlocking. For
example, a force-loaded wedge is provided on the
reinforcement profile that is guided in the opening 14
during the movement in lengthwise direction and that
allows a fastening of the reinforcement profile in the
receiving section by rotating the reinforcement profile
with respect to the receiving section.
[0055] The heald carrier profiles may have any
suitable shape and/or can be fastened to the transverse
elements in any way, for example as known from
WO 2011/023383, WO 2008/040559 or WO 2006/058565.
[0056] The heald frame, the transverse element, the
weaving machine and the method according to the
invention represented in the claims are not limited to
the exemplary embodiments illustrated and described by
way of example, but can also include variants and
combinations thereof that come under the claims.
