Abstract

1400959 Stamping; making lip seams SOLVAY & CIE 12 Nov 1973 [13 Nov 1972] 52387/73 Headings B3J and B3Q [Also in Divisions B5 B6 and B8] An apparatus for cold shaping synthetic resin blanks to form circular articles with at least one lug, e.g. a lid (24) with a tear tab (25), Figs. 9 and 10, not shown, comprises a punch 3, a die 4, and a blank holding ring 6 which includes a movable section 18 disposed in an area where the lug is to be formed and having a width at least equal to the width of the lug. As the die 4 is lowered the lug is punched by a bar 23 co-operating with a slot 22, spring-loaded section 18 prevents the lug from being torn. Upon further downward movement of the die 4, a flange is formed on the article, and at least one circumferential rib is pressed into the flange by a ring 9 of polyurethane which is expanded towards of groove 11 by downward movement of a member 5 when the die 4 reaches its lower stop. A circumferential cutter 12 partially severs the resin article to form a tear slit. Springs 19 which support the section 18 can be replaced by a fluid device.
