ABSTRACT:
Modification of a standard commercial multistation transfer press is disclosed to provide greater output capacity from that press, especially in producing workpieces which require a rolling operation in the forming process. The modified press utilizes double feed rolls of sheet metal strip, and pairs of duplicate blanking, drawing and rolling stations for processing the workpieces in pairs while being advanced through the press to complete the work.
