Abstract
A method of forming a container body having a profiled bottom in a continuous operation wherein the body is formed from a blank of material into an inverted cup, the cup is reverse drawn and a preliminary profile is imparted to the bottom of the cup, and a final profile is imparted. The apparatus includes a die cut edge movable into telescoping relationship around a redraw die to form the inverted cup and a profile punch movable into telescoping relationship within the redraw die to form the preliminary profile against a profile pad. The profile pad is selectively supported by a pair of fluidly actuated pistons whereby, upon activation of the second piston, the final profile may be formed.
