Abstract
Webs (12, 14) to be spliced are provided with end edges (24, 26) which are positioned with an overlap (38), covered by a metal buffer strip (60) and joined by application of ultrasonic energy (54, 62, 64).
Claims11
A method for splicing the trailing end of a first web to the leading end of a second web, comprising the steps of:
- providing each of the leading and trailing ends with a transverse end edge extended across a width of the web, at least one of the end edges having alternating fingers and spaces extended longitudinally of its respective web, to provide a length substantially exceeding the transverse width of its respective web;
- overlapping the end edges;
- and
- applying heat to locally melt the material at the end edges and pressure to cause the leading and trailing ends to join into a splice between the webs.
