ABSTRACT:
An apparatus for resistance welding of the longitudinal seam of can bodies by means of electrode rollers which are suspended so as to be oscillatingly drivable transversely with respect to the edges of the can bodies which are to be welded, in order to prevent premature wear of the electrode rollers due to the formation of notches, scoring or the like. The lower electrode roller which is additionally oscillatingly or reciprocatingly suspended in vertical direction provides outstanding accessibility and low dead mass of the moved parts.
