ABSTRACT:
A strip feed roller for feeding paper or paper-like material or the like. The roller is created for use as a part of apparatus, such as a folder machine, or the like. The strip feed roller has a cylindrical surface portion of substantially uniform diameter along the length thereof. The cylindrical surface portion of the roller has axially extending relatively straight sections of relatively hard or rigid material, such as metal, and relatively straight sections of a rubber-like material, such as urethane. The sections are arranged in alternating relationship. Thus, the roller is capable of applying a firm grip upon a strip, without creasing or wrinkling or cutting the strip. Also, the roller is capable of feeding the strip accurately and precisely without angular, lateral, or longitudinal slippage.
