Abstract
A bodymaker that transforms shallow metal cups into elongated can bodies includes a reciprocated ram which, during its forward stroke, drives the cups through a set of graduated circular dies. Ring shaped wipers engage the outer cylindrical surface of the ram and are arranged so that a first of the wipers scrapes tool coolant from the ram as the latter moves rearward and a second of the wipers scrapes hydraulic bearing fluid from the ram as the latter moves forward. The wipers are provided with flexible flaps that are in relatively low pressure frictional engagement with the ram resulting in only a very low temperature rise for the wipers to increase operating life thereof at production rates of approximately 400 per minute for cans of 21/2 inch diameter.
