ABSTRACT:
A can end manufacturing apparatus including an endless belt (1) having spaced apertures (12) for supporting the can ends (C) through the various stages of manufacture, said belt (1) being supported by spring-loaded travel rails (2, 3) arranged in guide slots (4) formed in longitudinally spaced supporting pillars (5) arranged on either side of a die station chamber (6) within which several die stations (7, 8, 9) and a sealant application station (10) are arranged. During each manufacturing operation, the transfer belt (1) is moved vertically so that each can end (C) is brought into engagement with the die stations (7, 8, 9) and the sealant application station (10). During this vertical movement, the atmosphere within the die station chamber (6) is alternatively compressed and rarefied. However, since the supporting pillars (5) for the travel rails (2, 3) are longitudinally spaced, the atmosphere within the die station chamber (6) is able to be adequately vented through said spaces (16) and under the travel rails ( 2, 3). In this way the disturbance of the atmosphere within the die station chamber (6) is substantially reduced and spatter of sealant during the sealant application stage is significantly reduced.
