Abstract

1,057,464. Stamping. EKCO CONTAINERS Inc. Aug. 18, 1964, No. 33768/64. Heading B3Q. [Also in Divisions B6 and B8] A method of forming a shell, Figs. 1 and 4 (not shown), from a metal foil blank (40) comprises pressing the blank between a die and a punch (32), at the start of the pressing operation the die and a gauge plate (33) being in non-clamping relation with opposite faces of the blank. A steel foil may be drawn down to form a cylinder with a diameter reduction of 36À2-47À3%, or an aluminium foil container (20) may be formed. The gauge-plate (33) advances with the punch until arrested by stop-screws (43S) without applying pressure to the blank. As the punch draws the blank into the die.eavity, the circumference of the blank is reduced, causing circumferential compression and a consequential increase in thickness of the flange-part of the blank engaged between the die and plate (33). Pressure between these parts and the thickened flange irons out any waves forming in the flange. Any wrinkles formed in the wall (220) of the container are finally ironed out by compression between the punch and die-wall.
