<p>On a machine for welding longitudinal edges (12, 14) of rounded bodies (10) of sheet-metal containers, a plurality of roller rings (24) are arranged in series in the feed direction (A) of the bodies (10), around a common longitudinal axis (22). At least some (28) of the rollers (26, 28) of the roller rings (24) are mounted on respective roller carriers (40) which are adjustable away from the longitudinal axis (22) counter to an elastic resistance. The roller carriers (40) are guided in a manner which permits the associated rollers (28) to perform yielding movements at an angle of significantly less than 90 DEG to the feed direction (A) of the bodies (10). For this purpose, the roller carriers (40) can each be pivoted about a transverse pivot (42) which is arranged at least approximately parallel to the associated roller spindle (38), ahead of the latter in relation to the feed direction (A) of the bodies (10). This guidance of the roller carriers (40) makes a significant contribution to the avoidance of damage to the forward edges (16) of the bodies (10) and to a reduction in the noise which arises when these forward edges (16) strike the rollers (28). <IMAGE></p> |
