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.
