ABSTRACT:
Machinery for three dimensionally forming register cut paper articles such as plates, bowls and saucers is operated with a single, register controlled material supply web and a 2:1 cyclic speed differential between the blank cutting station and the hot forming press. Rotational drive speed of the machine is set and limited by the cycle rate of the hot forming press but two or more, register cut product units are cut and stacked from a single ply, registered controlled web supply within a single cycle interim of the forming press. Consequently, the speed limiting step of the entire machine continues, with a single ply web supply to operate with a high percentage of maximum productivity.
