Abstract
A method and apparatus is disclosed for forming a butt splice to join together a web from a new roll of material to a web which is from an expiring roll of material and which is being run, downstream from the expiring roll, under tension along a predetermined path of travel that includes a running web storage means and a press or other web handling means. To form the butt splice, the leading end of the new web is trimmed along the cutting edge of an anvil. The trimmed leading end is held against the anvil, and a piece of tape is applied to the leading end so that a portion of the tape projects downstream from that end. The portion of the expiring web, adjacent to the anvil, is then momentarily stopped, held against the anvil, and trimmed along the same cutting edge of the anvil. As the trailing end of the expiring roll is trimmed, it is simultaneously adhered to the downstream portion of the tape. This serves to join this trailing end of the expiring roll and the leading end of the new roll together. Only the portion of the expiring roll adjacent to the anvil is momentarily stopped while the expiring web is trimmed and adhered to the leading end of the new roll. The stoppage is sufficiently short that downstream portions of the expiring web can, in the interim, be withdrawn from the web storage means so that web continues to run, at full speed, to and through the press.
