APPARATUS AND METHODS FOR JOINING WEBS

摘要

In a method of joining webs, the webs 48, 48b are overlapped and cut together, a cut-off portion (48a or 48d) is removed from the region of the cut, and adhesive material (119) is applied to marginal portions of the webs adjacent the cut to effect the join. The webs are stationary and a splicing head is moved across the webs carrying a cutter (126) and tape-applying means (125, 138). A plough 181 removes the cut-off portion. An effective butt join is formed and the webs may first be brought to a predetermined relative position using register marks 74. Adhesive material may be applied to both sides of the webs and the splicing head may be part of a splicing assembly between a turret and a festoon accumulator to allow uninterrupted running of the web.
