Abstract

Devices, methods, and systems for splicing a trailing edge of an outgoing roll with a leading edge of a replacement roll with a lapless butt splice on-the-fly during converting and printing production. A first strip of adhesive tape may be placed partially under the leading edge, such that a portion of the adhesive tape remains exposed beyond the leading edge. The replacement roll may be accelerated to match the speed of the outgoing web's movement, a trailing edge of the outgoing web may be cut free from the outgoing roll, and the trailing edge of the outgoing roll may be positioned over the exposed portion of the adhesive tape. A second strip of adhesive tape may be applied over the leading edge and trailing edge using a splicer roller timed to apply the tape when the edges pass proximate to the splicer roller.

Claims19

Dependent claims

A web splicer for on-the-fly splicing of an outgoing web with a replacement web, the replacement web being in the form of a replacement roll having a leading edge, the web splicer comprising:

a cutting apparatus configured to cut the outgoing web to create a trailing edge;
a bump roller rotatable about a central axis and configured to rotate in communication with the outgoing web, the bump roller arranged proximate to the replacement roll and further configured to press the trailing edge of the outgoing web against a first adhesive surface coupled to a leading edge of the replacement web and creating a gap between the leading edge and the trailing edge;
a splicer backup roller rotatable about a central axis and configured to rotate in communication with the outgoing web;
and
a splicer roller rotatable about a central axis, arranged proximate to the splicer backup roller, and configured to hold a second adhesive surface, the splicer roller configured to selectively press the second adhesive surface over the gap,
wherein the web splicer produces a web splice having the first adhesive surface arranged on a first side of the splice and extending across the gap between the leading edge of the replacement web and the trailing edge of the outgoing web, and the second adhesive surface arranged over the gap.
