ABSTRACT:
The disclosed butt splicing apparatus and method is adapted to be used with rolls of material supported on turret-type roll unwind stands. A splicer embodying the invention includes a nip assembly, a new web preparation assembly, a new web and tape holding assembly, and a web cutting and adhering assembly. The nip assembly serves to clamp the expiring web during a splicing operation. The new web preparation assembly serves to prepare the leading end of the new web for the splicing operation. The new web and tape holding assembly serves to hold a portion of the new web, immediately upstream of its leading end, and to hold a strip of adhesive tape in preparation for the splicing operation and during the splicing operation itself. The web cutting and adhering assembly serves to cut the expiring web during the splicing operation and to cause the cut part of the trailing end of the web and the leading end of the web to adhere to the adhesive tape simultaneously as the cutting of the expiring web occurs.
