ABSTRACT:
In a guide and calibrating tool for guiding container bodies for welding, at least one of the guide rollers is driven. The drive is pneumatic, by compressed air blown by a nozzle onto recesses in the roller. The roller is driven only initially upon restart of the welding machine or in the event of a break in the passage of a series of bodies, in order that no braking is caused by the arrival at the guide tool of the first (and possibly second) body. This enables the gaps between the bodies to be kept more constant even at the start of a series of bodies to be welded, and the first bodies to be welded do not suffer increased slip between the bodies and the welding electrodes.
