Abstract
A transfer device combines an advance-return drive mechanism and a clamp-unclamp drive mechanism. The transfer device operates from only one side of a press to position both drive mechanisms above a pair of feed bars thereby greatly reducing spatial constraints and costs and enabling an increase in speed. The feed bars operate to process a work piece along a process direction. The feed bars are cantilevered from the transfer device for easy use with a press, raw materials feeder, and product gatherer.
