System And Method For Multiple Layer Coil Winding

Abstract

The device for winding multiple layered material has a first shaft and a second shaft. A plurality of coils having a width are mounted to the first shaft. At least one guide is mounted between the first and second shafts. The guide has at least one slot with a horizontal surface and two vertical surfaces on each side of the horizontal surface. The second shaft has two flanges spaced apart at least as wide as the width of the plurality of coils. The slot in the guide receives at least one of the strips from the coils. Each strip from each coil is layered around the second shaft.

Description

FIELD OF THE INVENTION[0001]The present apparatus and method is directed to winding multiple coils of material strip into a single coil of multiple layers. The system may be used for a wide variety of materials such as metals, plastics and other materials, which may be wound into coils. The apparatus and method may also be used to wind multi layer coils around a single drum to create a coil with a larger number of layers.BACKGROUND OF THE INVENTION[0002]Long strips of material often come in coils of a single layer. In some instances, the coils originate from a wider coil of material that has been cut into narrower strips according to the specifications of the customer or the manufacturing process that will use the material. Machines in the prior art typically only create multiple coils of a single layer and do not wind multiple coils of material into a single coil having multiple layers. Therefore, if a customer desires a feed stock of material having multiple layers of material str...

AI Technical Summary

Benefits of technology

The present invention aims to create an even tension across each individual strip for an evenly wound multiple layer coil. This is achieved by utilizing existing coil and clutch assemblies in slitting machines. The technical effect is improved quality and consistency in the production of coils.

Problems solved by technology

Therefore, if a customer desires a feed stock of material having multiple layers of material strip, prior art machines do not solve the problem of how to wind multiple coils into a single coil in an efficient or economically feasible way.

Perrault does not disclose a guide or flanges to retain and orient the strips.

Thus, there is risk of the strips winding improperly.

Re-orienting the ribbons could cause too severe of a bend in many materials and would not be appropriate for all material applications.

In addition, Perrault does not disclose winding more than four layers around a single drum.

Kenney does not disclose a guide having a slot for each individual coil.

Further, Kenney does not disclose any means to guide the individual coils around a single drum.

Matsunaga does not disclose any means to guide the individual coils around a single drum.

Reed does not disclose any means to guide the multiple coils around a single drum.

Further, Reed does not disclose a guide or flanges to aid in winding multiple coils around a single drum.
