FIELD OF THE INVENTION
The present invention relates generally to magnetic sets attached to the frame of
embroidery machine and more specifically to an apparatus for securing cloth and
other embroidering surfaces in place in computerized machine.
BACKGROUND OF THE INVENTION
Various types of frames for holding an item to be embroidered are common place
for both home embroidery and commercial embroidery machines. Generally,
embroidery hoops comprise upper and lower hoops or clamping members that
mate with one another. Clothing is placed between the clamping members,
usually with a backing material also placed between the lower member and the
item to be embroidered. These types of hoops tightly pinch the material between
the vertical sides of the upper and lower hoops. Because of this, the lower hoop
member needs to be adjusted for any change in thickness of the item to be
hooped, which may not always result in the material being sufficiently taut or
tight, potentially resulting in an improperly embroidered piece of material.
The use of standard embroidery hoops becomes more difficult when the item to
be embroidered is a heavier or thicker material, such as a winter jacket, work
overalls, or items made of leather. Properly embroidering such items can be very
2
difficult and time consuming. It is very difficult to figure out what adjustment
should be made to the lower hoop or clamping member to securely hold the
garment, while not having too tight of an arrangement that the two clamping
members cannot properly mate with one another. It often takes multiple tries to
get the adjustment correct.
US Pat. No. 6,336,416 illustrates a clamp style prior art type of hoop or frame
that was designed to overcome some of these obstacles. This type of frame does
not need to pinch the fabric between vertical edges on its body, so this frame can
hold various thicknesses of fabric much easier. It pinches the material between
the faces of its upper clamping member and lower clamping member. These
clamping members are spring loaded to allow for different thickness of material to
be held without adjustment, but they do have limitations. One of the main
limitations of the prior art is how far from an edge of a garment that it can hold a
portion of fabric to be embroidered. This is because the device requires a pivot
point to properly operate. The arrangement makes placing a logo in the middle of
the back of a jacket, or on the left or right chest of a garment very difficult. If the
distance to the logo location is larger than the distance from the clamping
members to the pivot point, the material will need to be gathered in the pivot
point to reach the embroidery location, which is usually impossible or impractical
for these types of hooping machines.

Other problems arise when using computerized embroidery machines, since the
position and orientation of the embroidery on the item is a function of how the
item is captured within the hoop. Items to be embroidered are usually placed
directly within the clamps while they are mounted on the embroidery machine, as
it is difficult and time consuming to remove and reinstall the clamps onto the
machine. This creates extra downtime for the machine, since it is not possible to
have the next set of items hooped and ready to load onto the embroidery
machine. The finished items have to be removed from the clamps and the next
items have to be placed in the clamps, while the machine is waiting. The added
downtime becomes more evident on machines with multiple heads. Mounting the
fabric in the clamps while they are attached to the machine also makes aligning
the exact portion of the garment to be embroidered very difficult.
US Pat. Nos. 6,240,863 and 6,394,012 illustrate an alternative hoop or frame,
created to address the limitations of standard upper and lower hoop members.
These frames are designed to hold a special type of sticky backing material. The
garment is then placed over and adhered to the sticky material to hold it in place
while the embroidery operation is performed. This type of frame is very good for
getting into small areas like pockets on garments, or for sewing on delicate
fabrics, but is not really designed for everyday normal hooping of garments; it is
more for specialty items. One disadvantage to these frames is the need for
special sticky backing, which is generally more expensive than standard backing
and can leave a residue on the needles of the embroidery machine over time.

US Pat. No.5,138,960 discloses a magnetic monogramming frame. This frame
is designed to be mounted to the pantograph of an embroidery machine from its
lower member. The pantograph of the machine is the part that holds and moves
the embroidery hoop under the stationary needle to create the design. Mounting
a hoop directly to the pantograph requires that you physically fasten the hoop to
the pantograph or that you fasten a separate adapter directly to the pantograph.
Newer style machines use a set of arms that extend out from the pantograph and
have adaptors on the ends of the arms that allow for quicker and easier mounting
of hoops. The hoop from this prior art device is not designed to be releasably
mounted to the existing hoop holding arms on these newer style commercial
embroidery machines. This outdated design increases the time it takes to switch
from using one type of frame to another. This prior art frame also incorporates
continuous magnetic tape type material instead of separately mounted magnets.
This type of magnetic material arrangement does not provide any automatic
alignment between the upper and lower members of the frame. The frame of this
prior art device pinches the material directly between the magnetic materials; it
also does not provide a ridge to help hold the material to be embroidered taut
and against the needle plate of the embroidery machine. If the material to be
embroidered is not held stretched and against the needle plate this causes
bouncing of the material during the embroidery process. This bouncing can
cause looping of the embroidery thread and an undesirably look of the finished
embroidery.

The magnet sets are fixed in order to attach the iron clip of the embroidery
frames. Due to use of the plastic or polymers fibre of magnetic sets and frictions
therein, the parts of the set gets damaged and need to be replaced frequently.
Due to damage of the magnetic sets, the embroidery work could not be carried
out with accuracy and precision and need to be replaced with new one. In the
course of embroidery, the embroidery frames are frequently detached and fixed
time and again with the embroidery machine after completion of every piece of
embroidery work. After completion of embroidery work over one piece of
fabric/cloth the embroidery frames are removed from the embroidery machines
and the new piece of fabric/cloth is fixed with the embroidery frame and
embroidery frame is again fixed with the help of magnetic sets. In the course of
embroidery process and on account of frequent use of the embroidery frames
and magnet sets in order to fix it and detachment and further due to friction and
its frequent use the magnetic sets gets damaged and/or its grip to hold the frame
is reduced and therefore the magnetic sets need to be replaced frequently. The
replacement of magnetic sets on frequent basis burdens with additional
exorbitant cost.
OBJECTIVE OF THE INVENTION
1. The objective of the present invention is to provide a more durable magnet
sets than the traditional magnet sets which are made of plastic/ polymers.
6
2. Another objective of the present invention is that it is cheaper than the
traditional magnet sets.
3. The another objective of the magnetic set is that it keeps the embroidery
frame very much sticked/gripped to the embroidery machines and it gives
additional strength to the fixed/attached position of the embroidery frame
with the embroidery machines. Accordingly the cloth/fabrics remain in
much stretched position fixed in the frame which improves the quality of
the embroidery with more precision and accuracy.
4. Another objective of the present invention is to increase the life time of the
magnet sets which are helpful in finest embroidery.
5. Also the present invention is one step beyond the present technology and
it could serve as the base for revolutionary upcoming technology.
SUMMARY OF THE INVENTION
The present invention relates to the metallic magnet sets for computerised
embroidery machine for getting accurate and beautiful embroidery. The
aluminium frames are used in the computerised embroidery machine which is
used to fix the fabrics in stretched position in the embroidery machines. The
magnet sets are used to fix the embroidery frames with the main frames of
embroidery machine. Embroidery frames consists of iron clip which is
7
attached/fixed with the main frame. The magnet sets take hold of the iron clip of
embroidery frame very strongly due to high magnetic effects which can be
detached easily without using considerable force. The aluminium magnetic sets
consist of two parts of the magnet set and the other part is fixed with the help of
screw/ribit. The present magnet sets can be hardened aluminium, brass and
stainless steel in stead of polymers. The present magnet sets keeps the
embroidery frame very much sticked to the embroidery machine and it gives
additional strength to the fixed/attached position of the embroidery machines so
that the cloth/fabrics remains in much stretched position fixed in the frame which
improves the quality of the embroidery with more precision and accuracy. Due to
use of the metallic magnet sets the parts of the magnetic sets rarely gets
damaged and it works for long duration and gives satisfactory result.
