Abstract

644,709. Seaming. SPENCER PRESS, Ltd., and GINZLER, S. March 11, 1948, No. 7497. [Class 83 (iv)] [Also in Group XVII] A non-metallic frangible disc is secured across a can opening by rolling over the top edge of the can inwardly together with a peripheral portion of the disc. The apparatus comprises supporting members 13, 14, spaced apart by springs 17 such that when the flanged disc 10 is placed on the upper part 14 the edge of the flange 12 lies a short distance below the edge of the can 11, and a punch 24 having a circumferential groove 27. The initial gap between the members 13, 14 is adjusted by means of a screw 22, so that by the time the members are brought into contact by the pressing operation, the seaming is completed, Fig. 3 (not shown). A flanged metal lid 31 may be subsequently fitted.
