Abstract

1,111,823. Sheet forming. ILLINOIS TOOL WORK Inc. 6 May, 1965 [8 May, 1964], No. 51641/67. Divided out of 1,111,821. Heading B5A. A container having a beaded lip is made by plunger assist blow forming a peripherally clamped heat-softened sheet between male and female dies, the upper peripheral region of the drawn part of the article being clamped between surfaces 86 and 106, on the male and female dies respectively, upon full penetration of the male die. The region 132 of the sheet located between the two clamped portions is subsequently severed between surfaces 136 and 138 by further downward movement of the male die, under the action of its internal stresses, said region 132 contracts to form a beaded lip 134.
