ABSTRACT OF THE DISCLOSURE: Apparatus so constructed that narrow can bodies having an internal diameter of 52 mm for example can be produced from rounded blanks by welding the edges of the blanks. The supply of welding current to the electrode roller is effected through copper caps, a clamping member, contact members disposed at each side thereof, contact jaws silver contact segments and peripheral surfaces of broad hubs which are provided on the electrode roller. The contact jaws engage round the hubs of the electrode roller at both sides, above and below, as a result of which a large area for the transmission of current and a low specific contact pressure result. The hub surfaces, which form the actual contact surfaces of the electrode roller, are continuously lubricated through felt lubricating segments. The contact pressure of the contact jaws can be adjusted in a simple manner by means of a screw. The whole apparatus and particularly the electrode roller are intensively cooled internally by a special cooling device.
