ABSTRACT:
A pair of sheets are supported on a support assembly having skewed support rollers disposed on opposite sides of an elongate guide having a pair of sidewardly opening and vertically overlapping guide grooves. The pair of sheets are disposed on opposite sides of the guide and are urged inwardly into the guide grooves so that adjacent edges of the sheets are vertically overlapped. A shuttle moves the overlapping pair of sheets toward the nip of a weld roller assembly, with the sheets being engaged by driving skewed rollers disposed directly adjacent the weld roller assembly. The sheets are drivingly moved through the nip of the weld roller assembly, with the weld roller assembly having upper and lower weld rollers which pressingly and drivingly engage the overlapping edges of the sheets therebetween to create a seam weld as the sheets move through the nip. A planish roll assembly having upper and lower planish rolls engages the seam weld directly downstream of the weld rolls to effect mashing thereof so that the resulting seam weld has a thickness which is not significantly greater than the sheet thickness.
