ABSTRACT:
A forming machine for making shallow cups is provided. It has a cylindrical secondary form with a top surface adjacent to which a blank may be positioned. The secondary form is spring-mounted so that it can move during the forming operation. The pressure applied by the spring to the form is adjustable. A forming punch presses the blank, and in turn the secondary form, and moves them further into a body member so that the blank is formed into a shallow cup with the sidewall of the cup positioned around the forming punch.
