process for rollnahtschweissen containers and rollnaht - widerstandsschweissmaschine for implementation of the procedure

摘要

The roller seam welding machine (1) is provided with a contour-controlled tool table (2) for the receptacle (3) to be welded. The table is driven in a known manner by a pinion (4) and a pantograph (16). In order to also be able to weld three-dimensionally running welding flanges (6) of the receptacle (3), the welding rollers (10, 11) are arranged on a vertically traversable head (14) of the machine. The welding rollers can thus be traversed in accordance with the rising or falling welding flange (6). Owing to the fact that the tank is moved only in a conventional manner in a horizontal plane and in addition the welding rollers are moved vertically, the possibility of also welding three-dimensionally running welding flanges of receptacles with high precision irrespective of weight or size of the receptacles is obtained in a simple manner.
