Abstract: A guide roller for aligning successive turns on a coil of a ribbon-like web. The guide roller automatically positions itself to maintain a uniform clearance space between the incoming web and the circumferential periphery of the coil. The clearance space is provided to prevent a marring of a coating on the surface of web material. As the coil radius increases during the winding process, the guide roller maintains a constant and uniform clearance space responsive to the changing angle between the incoming and outgoing web passing over the guide roller.

Abstract: A hub lock for a coil forming machine has a spindle with a shaft telescopingly mounted within a tube that is concentric thereto. A metal part somewhat in the form of a top hat is positioned over an end of the tube. A resilient elastomer block is on the crown and abutting against the brim of said top hat shape. A pressure plate on the end of the shaft squeezes the elastomeric block so that it is pressed against the interior of a hole in a wheel fitted over the block.
