Method of manufacturing a seam connection between body flanges (9) and end wall flanges (5) of a drum (11) by means of a seaming roller (14) which folds the flanges about eaach other, the essential difference with respect to prior art seaming operations being that the precurl (6) of the end wall flange (5), known in itself, is guided into the lower portion of the groove (15) of the seaming roller so that during the radial movement inwardly of the seaming roller (14) the flanges (5,9) may bulge outwardly in axial direction and form a so called cat\s back by means of which the flanges and accordingly end wall (2) and body (1) are centered upon each other, whilst further a distance is provided between the upstanding edge (3) of the end wall (2) and the curvature (10) between body (1) and body flange (9) which distance during the seaming operation may be reduced. It moreover is possible by using a support (13) for the end wall which is smaller in diameter than the diameter of the body (1), to perform the seaming operation inwardly to a degree such that the final seam has an outer diameter which is substantially equal to the diameter of the body (1).

In a method of manufacturing a seam connection, between and edge of a radially outwardly extending flange (9) at one end of a body (1) of a metal container which is a figure of revolution having an axis, and an edge flange (5) of a metal end closure wall (2), in which said edge flange (5) is provided with a precurl (6) with a small radius, the inner diameter of said precurl (6) being larger than the thickness of the end edge (11) of said extending flange (9), which extending flange (9) at the location of a transition (10) toward the body (1) has a curvature having a radius of a magnitude such that a gradual bend transition is obtained from the body (1) toward said extending flange (9) and said edge flange (5) of said end closure wall (2) merges into said end closure wall (2) by a curvature (4), which edge and extending flanges (5, 9) after placing and axially pressing said end closure wall (2) and said body (1) upon each other are rolled into each other with the aid of at least one seaming roller (14) having a groove (15), which roller (14) is displaced in circumferential direction with respect to said body (1) and radially toward the body (1) to perform the rolling into each other of said edge and extending flanges (5, 9) inside said groove (15) of said seaming roller (14) with simultaneous centering and supporting of said end closure wall (2) on the inner side of said edge flange (5) of said end closure wall (2), said groove (15) of said seaming roller (14) having a height (K), which is larger than a thickness (V) of said precurl (6) measured in a direction parallel to said axis; the improvement wherein an upstanding edge (3) of said end closure wall (2) and said transition (10) between said body (1) and said extending flange (9) are entirely spaced apart from each other, and wherein said precurl (6) at the beginning of the seaming operation is guided into that portion of said groove (15) of said seaming roller (14) which, seen in axial direction, is closer to the other end of said body (1), and wherein it is an underside (12) of said precurl (6) which first comes into contact with said portion of said groove (15).
