Abstract
A planetary crank drive gear arrangement for a conveyor drum in a folder of a web-fed rotary printing machine is disclosed. The planetary crank drive gear arrangement includes a pair of spaced planetary gears which cooperate with a sun gear through which the shaft of the conveyor drum passes. A swing disk is carried on the conveyor drum shaft and is so weighted to compensate for the additional weights added by the planetary crank drive gears and the like. The planetary crank drive gear arrangement allows the conveyor drum to be either accelerated or decelerated without adversely affecting the drive for the printing machine.
