ABSTRACT:
The feeder and the rolls are operated by separate cranks to avoid obstruction of the area in which the hollows are connected to the feeder. The two cranks are either separately driven or connected to a common drive; in either case, synchronism is maintained, and, preferably, an alternating retarding and advance component of movement is superimposed on one crank in relation to the other so that the feeder drive can take up some of the deforming work.
