Abstract
A frame-like roller carrier (40) which defines a sizing plane (C) normal to the longitudinal axis (A) of the can bodies is arranged in relation to awelding device (24) in such a manner that the sizing plane (C) coincides at least approximately with a welding plane (B) defined by the welding device. A plurality of sizing rollers (41) are mounted on the roller carrier (40), each for rotation about a roller axis (E) lying in the sizing plane (C). The sizing rollers (41) form a rigid ring of rollers through which the can bodies (1) can be moved. The roller carrier is divided into two half-frames (40), each of which carries a plurality of sizing rollers (41). The two half-frames (40) are adjustably supported on a common bridge (31). At least one of the half-frames (40) is connected to the bridge (31) by an adjusting drive (37) for the adjustment of the sizing rollers (41) carried by it. Consequently, the sizing tool (30) can be adjusted with little labor, for example if the overlapping width of the can longitudinal edges to be welded to one another has to be altered.
