Abstract
A mechanism for advancing a rotating cylindrical member which has a frame and opening to accept a cylindrical member extending therethrough in a first line, and an advancing roller for engagement with a cylindrical member extending through the frame opening. The advancing roller is mounted to the frame for rotation about a first axis that is transverse to the first line to thereby cause a rotating cylindrical member in the frame opening that encounters the advancing roller to be advanced along the first line substantially parallel to the frame opening axis. The advancing roller is preferably carried by a mounting block which is mounted to the frame movably between first and second positions. By moving the mounting block between its first and second position, the advancing roller is moved towards and away from the frame opening axis to thereby vary the distance of the advancing roller from the frame opening axis to accommodate different diameters of cylindrical members to be advanced by the mechanism. Structure is provided to prevent movement of the advancing roller away from the frame opening axis in first and second different positions for the advancing roller relative to the frame opening axis and to allow selection of the first and second advancing roller positions without disassembling any part from the advancing mechanism.
