Abstract
A gang punch tool assembly and method is provided for punching holes in a plurality of greensheets which are processed sequentially through the assembly. The punch mechanism is a gang punch cooperating with a corresponding die and the greensheet is automatically fed to the gang punch and die, the greensheet punched and then the punched greensheet removed from the punch area and another greensheet positioned for punching. Operation of the gang punch apparatus is efficient and effective and has a high greensheet throughput. A preferred gang punch uses a pressurizable air chamber for controlling punching of the greensheet without damage to the greensheets or gang punch mechanism.
