DESC:FIELD OF THE INVENTION
[001] The present invention relates to a coiler plate apparatus or coiling arrangemnt in a textile spinning preparatory machine. More particularly, the present invention relates to a coating and process thereof on the bottom surface of the coiling plate in Drawing machines / Carding machines / Combing machines.

BACKGROUND OF THE INVENTION
[002] Usually spinning preparatory machine development focused primarily on natural or man-made fibre processing. The usage of can coiler in the textile spinning preparation machine such as card, comber and draw frames, for depositing the sliver gently in to the sliver can is known. Normally the cans are kept over a revolving table and rotated at a predetermined speed by the drive system of the textile machine. Therein a coiler head for said textile machine is provided that comprises a sliver canal and a bottom surface which constantly rubs the top layers of the slivers deposited in the sliver can. Said sliver can is also rotated at a predetermined speed by the drive system of the textile machine. For proper deposition of the sliver, the bottom surface of the can coiler being provided with predetermined and optimum surface roughness.

[003] The surface roughness often getting changed due to the constant rubbing of the bottom surface of the can coiler plate with the sliver material which is held against the bottom surface of said coiler plate by predetermined spring force exerted by the springs arranged inside the sliver cans. Due to the above phenomena, the bottom side of the can coiler plate becoming smoother over a period of time, especially within a very short period while processing natural or man made fibre material. This results in improper coiling appearance and disturbed pattern of sliver loops. This leads to quality complaints in output fibre strand, production efficiency and frequent production interruptions in cleaning work.

OBJECTS OF THE INVENTION
[004] Primary objective of the present invention to provide a simple and improved coating for the coiler plate of textile machines.

[005] Another object of the present invention is to reduce the surface friction of the coiler plate to improve the coiling appearance of sliver while processing natural or man made fibres.

[006] Yet another object of the invention is to improve the unwinding behavior of coiled sliver in subsequent process thereto avoid unnecessary stoppage due to entangling of fibre loops.

[007] One more object of the present invention is to provide the coiler plate with improved service life compared to conventional coiling plate.

[008] Further objects of the invention will be brought out in the following part of the specification, wherein detailed description is for the purpose of fully disclosing the invention without placing limitations thereon.

SUMMARY OF THE INVENTION
[009] The coiler plate according to the inventions is provided with a coating on the bottom surface facing the sliver-can. This reduces the friction between the coiler plate and the deposited fibres in the form of circular loops. With reduced friction, the deposited fibres are less disturbed and has a uniform appearance and quality. This is more advantageous especially while processing man made fibre and blends thereof. Coiler plate according to the invention is provided with a special epoxy based coating which offers lower frictional resistance with fibres being processed. With this coating, the deposited fibre sliver inside the can is less disturbed and has a more uniform pattern of fibre loops. Preferably the coating has add-on substances like ceramic particles which resists wear and abrasion of the coating. Thus the coiler plate of the textile processing machine coated with a ceramic reinforced epoxy coating, advantageously exhibits a relatively low coefficient of friction with respect to the natural or man made fibers or the blends, and therefore relatively low frictional forces are exerted on the sliver.

BRIEF DESCRIPTION OF THE DRAWINGS
[0010] With the above and other related objects in view, the invention consists in the details of construction and combination of parts as will be more fully understood from the following description, when read in conjunction with the accompanying drawings in which:

[0011] Figure 1 shows the cross-sectional view of a coiling arrangement of the textile-processing machine according to the present invention; and

[0012] Figure 2 illustrates the magnified view of coating section of coiler plate apparatus according to the present invention.

DETAILED DESCRIPTION OF THE INVENTION
[001] The following detailed description is intended to provide example implementations to one of ordinary skill in the art, and is not intended to limit the invention to the explicit disclosure, as one or ordinary skill in the art will understand that variations can be substituted that are within the scope of the invention as described.

[0013] Referring to FIG. 1, a textile-processing machine 10 comprising a coiling arrangement 30 is shown, in accordance with one embodiment of the present invention. The textile-processing machine 10 comprises a sliver can 15. Further, the textile-processing machine 10 comprises a coiler plate 20. The coiler plate 20 might be made up of metal. Further, the collier plate 20 is covered at the bottom by a bottom cover or sheet 25. The bottom cover 25 is made up of stainless steel or alloys.

[0014] Further, the textile-processing machine 10 comprises the coiling arrangement 30 having a coiling pot 35 rotatably mounted, which guides the condensed fibre sliver through a canal 40 into the sliver-can 15 and forms a circular loops of sliver S to store them. As can be seen, the bottom cover or a sheet 25 is fixed to the underside of coiler plate 20. It should be understood that the bottom cover 25 of the coiler plate 20 is always in contact with the top layers of the coiled slivers S of the sliver-can 15 throughout the production process. This is to provide necessary compact package of the sliver material in the sliver-can 15 which would be required for subsequent flawless unwinding of sliver in next spinning line machine.

[0015] Now referring to FIG. 2, a special epoxy based coating preferably ceramic reinforced epoxy coating 45 applied on the surface of the bottom cover 25 of the coiler plate 20 is shown, in accordance with one embodiment of the present invention. The ceramic reinforced epoxy coating 45 is selected to have lower frictional resistance with fibres being processed. The ceramic reinforced epoxy coating 45 provides reduced frictional resistance to the bottom cover 25 and therefore provides improved fibre sliver quality such as uniformity and appearance of sliver etc. Before applying any treatment over the bottom cover 25, the surface of the bottom cover 25 is prepared by undergoing grit blasting and solvent cleaning. During the process, the degree of surface preparation determines the quality and appearance of the subsequent coating finish.

[0016] In one implementation, the ceramic reinforced epoxy coating 45 is applied by spraying the ceramic reinforced epoxy material or brushing the ceramic reinforced epoxy material on bottom surface of the bottom cover 25. The ceramic reinforced epoxy coating 45 is applied such that the thickness of coating is obtained in the range of 0.05mm to 2.0mm. Preferably, the ceramic reinforced epoxy coating 45 is provided with thickness of 0.2mm. Subsequently, the coiler plate assembly is cured in 24 hours at room temperature or in oven cured at much shorter time. After completing the curing process, the appearance of coating becomes more smooth spray-painted texture or has brushed texture.

[0017] As specified above, the ceramic reinforced epoxy coating chemical composition 45 can be applied on surface of the bottom cover 25 by spray or brush. This is because; the ceramic reinforced epoxy coating 45 provides a superior adhesion and forms a solid bond between coiler plate 20 and the ceramic based epoxy coating 45.

[0018] Advantageously, the ceramic reinforced epoxy coating 45 offers maximum protection to the bottom cover 25. The ceramic reinforced epoxy coating 45 may also be applied directly over the bottom surface of coiler plate 20 where there is no necessity for bottom cover 25 and so that the sliver coil S is directly in contact with the coiler plate 20.

[0019] Specific benefit of the invention provides improved unwinding behavior to the sliver in subsequent process and avoids stoppage due to entangling of fibre loops, which increases production rate of the textile spinning preparatory machines.

[0020] In view of the present disclosure, which describes the present invention, all changes, modifications and variations within the meaning and range of equivalency are considered within the scope and spirit of the invention. It is to be understood that the aspects and embodiment of the disclosure described above may be used in any combination with each other. Several of the aspects and embodiment may be combined together to form a further embodiment of the disclosure.
