Butt splicer for butt-joining a fresh web to a running web
Abstract
Abstract A butt splicer for butt-joining a new we b to a progressing web which permits to join both webs without any risk for edge-overlapping. The splicer comprises a stationary and a displaceable clamping head for clamping the webs together preparatory to splicing, a cutter for simultaneously cutting both webs transversely while they are pressed together by the clamping heads, a tape applicator for taping the webs together at one side after the cut-off end of the web at that side has been removed, and a bar extending transversely of the web path and displaceable through the clamping plane, within the clamping zone, to cause localized bowing of one web and consequent displacement of its cut end away from the cut end of the other web before such we bends are taped together.
