Abstract
Abstract A strip shearing and welding apparatus in which the exit end strip clamp assembly remains stationary and the entry end clamp assembly is indexed after shearing to bring the leading end of the new strip clamped thereby into proper alignment with the trailing end of the old strip for welding. The welding assembly is mounted for vertical movement with the exit end clamp assembly to avoid damage to the weld assembly through premature opening of the clamp assembly and maintain the location of the weld assembly both vertically and horizontally with respect to the exit end clamp assembly for proper orientation of the weld assembly with respect to the strip end held thereby.
