ABSTRACT:
Two endless flexible conveying strands (22, 24) run, parallel to one another, over a drive mechanism (26, 28), a guide mechanism (30, 32, 34) and a conveying track for the body blanks (10). The two conveying strands (22, 24) are displaceable in relation to one another to a limited extent in their longitudinal direction in operation. Pusher dogs (46, 48) are secured one behind the other to the conveying strands (22, 24) with equal spacing so that situated opposite each pusher dog (46) on one conveying strand (22) is a pusher dog (48) on the other conveying strand (24) so that these two associated pusher dogs together push a can body blank (10) over the conveying track to a welding apparatus (20). The pusher dogs (46, 48) each have a lateral projection (50, 52). Disposed on the conveying track, upstream of the welding apparatus (20), at a distance from this which coincides at least approximately to the length of the can body blanks (10), is a pair of adjusting templates (62, 64). The adjusting templates (62, 64) are rigidly connected to one another and can be brought into engagement with a pair of associated projections (50, 52) in order to bring these forcibly into alignment with one another in a direction transverse to the conveying track.
