Abstract

1301270 Making can bodies; flanging METAL BOX CO Ltd 19 April 1971 [8 April 1970] 16622/71 Headings B3A and B3E An end-necked metal can body is made by forming an outwardly-curved end flange 19 (dotted lines) around an open end thereof and subsequently forming, by rolling, a neck 12 (solid lines) immediately behind the flange so that the flange merges directly with the neck. The rolling operation can be performed using a co-operative mandrel and beading roller (Fig. 1, not shown) which can approach each other radially during their relative rotation. The profiles of these parts comprise continuously curved portions arranged to allow for spring-back so that no bulging exists below the neck. Both ends of a can body may be necked simultaneously to the same or different depths. Longitudinally seamed bodies, particularly with soldered or cemented seams, can be dealt with. An apparatus (Figs. 4-8, not shown) for performing the end necking includes one or a pair of beading rails of decreasing radius, along which the cans are moved while being rotated by holding mandrels.
