ABSTRACT:
A method of and apparatus for forming a butt splice between an expiring web and a new web in which both webs are concomitantly cut at a location upstream of a lap splice formed between the webs and a length of splicing tape is applied at the location to form the butt splice. After the butt splice is formed, the new web leading portion which is severed during the cutting operation is stripped from the expiring web. Preferably a stiffener strip is adhered to the expiring web with a breakaway adhesive and to the new web with a firm adhesive during the formation of the lap splice to facilitate the subsequent stripping operation.
