HEAT-SEAL SPLICING ASSEMBLY AND METHOD

摘要

A method and web splicing assembly (12) for heat-seal splicing together a trailing end of running first, two-sided plastic material web (28) and a leading end of a second, two-sided plastic material web (34), and then for heat-seal splicing together a leading end of third, two-side plastic material web (42) and the trailing of the then running, second web (34). The web splicing assembly (12) includes first and second splicing subassemblies (14, 16). Both sub-assemblies (14, 16) have relatively movable slide bars (112) and relatively fixed nip bars (84). The subassemblies are each movable between a first position and a second position. Each slide bar (112) carries a heated wire (146) that heat-severs the clamped web portions along a localized area that extends across the web portion and heat-seals parts of the clamped web portions together adjacent to the area.
