ABSTRACT:
The method hereof, conducted at the factory or site of printing of the wall covering, advantageously uses the same work or printing station reference that accurately positions the imprinted pattern on the wall covering substrate for the positioning of cutting means effective to sever said substrate free of the opposite unprinted selvage areas. Thus, although the substrate, which typically is a 100-foot strip, may be inadvertently slightly misaligned from a perfectly straight orientation, the cutting means nevertheless effectively moves along that path which accurately slits free the selvages of the "misaligned" substrate because it is guided by said imprinting reference during said movement.
