ABSTRACT:
Sheet-metal members (10), particularly tear-open can members, can be moved rhythmically, one behind the other, through a welding station (19) by a sheet-metal conveyor (15) and located in a defined position (17) in the welding station (19) by a positioning device (17). A prestamped tongue (12) can be punched-off from a sheet-metal strip (58) each time by a punch (60) over one of a plurality of receivers (52) on a tongue conveyor (18). The receivers (52) can be moved in succession out of the range of action of the punch (60) into the welding station (19) as a result of which the tongues (12) can each be laid against a sheet-metal member (10) in the welding station (19) in time with the sheet-metal conveyor (15). The punch (60) for punching off the tongues (12) is preceded by a prestamping device (82) which impresses markings (84) in the sheet-metal strip (58) at fixed distances from the tongues (12).
Disposed between the prestamping device (82) and the punch (60) is a drive member (83) which engages the markings (84) in the sheet-metal strip (58) and is connected to the tongue conveyor (18) by a transmission (86). The punch (60) is connected to a centering device (90) which engages in at least one marking (84) adjacent to it in the sheet-metal strip (58), during the punching off of a tongue (12). In this manner, the tongues (12) are each particularly accurately positioned in relation to the associated sheet-metal member (10).
