Can bodies (1) rounded around an arm (16) are taken over by endless conveying tracks (30;50). These are each guided over guide devices (32;52) and a drive wheel (33;53) and each comprise a run parallel to the arm (16) in order to convey the can bodies (1) along the arm (16) in the direction of a welding station (70). The guide devices (32;52) are mounted on track carriers (26;46) and form, together with these and the associated conveying track (30;50), units adapted to the length of the can bodies and interchangeable as a whole. These units are each secured to a sliding carriage (22;42) which is adjustable at least substantially radially to the arm (16). Track carriers (26;46) provided for different ranges of can length can be exchanged for one another with a few movements of the hand and each track carrier (26;46) can be adjusted by the associated sliding carriage (22;42) in such a manner that its arrangement is adapted in an optimum manner to can bodies (1) of any desired diameter within the working range of the machine. |
