摘要： Apparatus for use in a processing line through which strip travels longitudinally, such apparatus functioning to join the trailing end of a first strip portion to the leading end of a second strip portion along a transverse line of juncture to form a continuous strip length. The apparatus includes a flashwelder for joining the first and second strip portions, a trimmer for removing the weld flash from opposite faces of the strip at the line of juncture, a notcher for removing weld flash at the line of juncture at opposite side edges of the strip and including means for removing the abrupt shoulder formed at the line of juncture at at least one side edge of the strip when a relatively narrow first strip portion is welded to a relatively wide second strip portion. The apparatus also includes punch means selectively operable with the notcher to pierce the strip adjacent the line of juncture to facilitate identification of the latter during subsequent processing of the strip. The apparatus further includes means for locating the notcher in predetermined operational relation with the side edge aforesaid of the first strip portion.
