Abstract
A butt splicer for butt-joining a fresh web to an expiring web, which comprises two relatively displaceable clamping members and one intermediate clamping member, which determine for the two webs common and separate clamping paths. The two webs are cut simultaneously while being on their common paths, one web is cut while being on a separate path, and the two webs are taped together after the strip of said one web comprised between the two cuts has been removed. Butt control means preferably cause a slight separation of the corresponding web end edges before the web ends are taped together.
Claims14
A butt splicer for butt-joining a fresh web to an expiring web, said splicer having portions thereof arranged to define adjacent aligned superposed paths for the webs, which splicer comprises relatively displaceable clamping means for clamping, preparatory to splicing, said web portions firstly along a common path and subsequently along separate paths, considered according to the direction of movement of the webs, cutter means arranged for displacement transversely of the webs for cutting both webs progressively transversely along a first line situated on said common path and for cutting one of said webs along a second line situated on a said separate path, means for removing the strip of said one web which is located between the two lines of cut, and means for applying a tape splice to the adjacent end portions of the webs produced by the cutting of the webs along said first line, while the webs are still clamped by the clamping means.
