Abstract
This invention is a constant flow container manufacturing device and process which consists of a rotating die drum device containing three paper punching machines capable of punching a circular container bottom, a rotary conveyor system synchronized at the same speed as the rotating die drum device and containing a plurality of rotatable mandrels thereon, said mandrels being synchronized to pass opposite the rotating paper punching machine. Means of transferring the container bottom from the rotating paper punching device to the moving mandrels. A paper clamp, positioned on the mandrel, adapted to clamp the edge of a pre-gummed paper blank, which rotates around the mandrel as it turns, pressing the pre-gummed paper blank to form a cup-like container on the mandrel.
