ABSTRACT:
The invention relates to a process for guiding workpieces on a rolling seam welding machine or vice versa. In the process the relatively moved part is driven via its guide means of a continuous path manipulating device in an extra conveyor motion in the same direction and with the same speed as a tool-caused conveyor motion. The two conveyor motions are monitored for synchronicity by a displacement sensor that is connected for control purposes with a control unit of the manipulating device. When a difference occurs between the two conveyor speeds, manifested by the turning of the moved part around the displacement sensor, one of the two conveyor speeds is readjusted, with short-term over-compensation of the difference.
