A drive system for rollers in pressure indented relation including a lug on a drive gear, which is rotatably mounted about one of the roller journals, and a projection on the roller journal such that the gear will drive the roller only when the lug and the projection are in engagement. The system provides a drive for driving rollers at different surface speeds, the drive being adapted to permit rotation of the rollers at equal surface speeds until lubricant is transferred to the nip between the rollers and thereafter at different surface speeds. |
