Abstract 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.
An apparatus for welding the trailing end of one strip to the leading end of another longitudinally aligned strip to enable the joined strips to be moved through a processing line in a predetermined direction, and wherein a side edge of said other strip extends beyond the corresponding side edge of said one strip to produce an abrupt overhanging corner which presents an extending generally right-angled shoulder that is undesirable in that it may interfere with subsequent working of the strip, the improvement comprising, die means positioned at an edge of the joined strip and having shear blades which cut an arcuate portion from the joined strips at the line of juncture and a rectilinear portion from said shoulder, said rectilinear portion being tangential to the rear part of said arcuate portion with respect to the line of strip movement and tapering from said rear part to the side edge of said other strip.
