Support drum assembly with cross-shaft linkage for variable backlash control

摘要

A support drum assembly is provided for a torque, nip and web tension type of reel. The support drum assembly includes an actuating mechanism disposed at one end of the support drum which enables one end of the drum to be raised or lowered with respect to the other end of the drum for adjusting the amount of backlash while the machine is in operation. The support drum assembly includes a cross shaft linkage which will allow at least two different backlash settings to be used at any time during the machine operation.
