Automatic lapless butt material splice
First Claim
1. A web splicer for on-the-fly splicing of an outgoing web with a replacement web arranged about a replacement roll and having a leading edge, the web splicer comprising:
- a cutting blade 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 the replacement web;
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 receive a second adhesive surface, the splicer roller configured to selectively press the second adhesive surface against the leading edge of the replacement web and the trailing edge of the outgoing web;
wherein the web splicer produces a web splice having the first adhesive surface arranged on a first side of the splice and extending across both the leading edge of the replacement web and the trailing edge of the outgoing web, and the second adhesive surface arranged on a second side of the splice and extending across both the leading edge of the replacement web and the trailing edge of the outgoing web.

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.

10. A method for splicing a replacement web with an outgoing web on the fly, the method comprising:
-
accelerating rotation of the replacement roll to match a speed of the outgoing web, the replacement roll having a first adhesive strip affixed to an inner surface of a leading edge of the replacement web, such that a portion of the first adhesive strip remains exposed; arranging a second adhesive strip on a splicer roller, the splicer roller rotatable about a central axis; accelerating rotation of the splicer roller to match a speed of the outgoing web; cutting the outgoing web to form a trailing edge, wherein cutting the outgoing web causes the trailing edge to contact the exposed portion of the first adhesive strip; pressing the trailing edge onto the first adhesive strip, adjacent to the leading edge; and affixing the second adhesive strip over the trailing edge and the leading edge via the splicer roller, such that the second adhesive strip contacts both webs. - View Dependent Claims (11, 12, 13, 14)

15. A system for splicing a replacement web with an outgoing web on the fly, the system comprising:
-
a plurality of rollers facilitating movement of the outgoing web and replacement web; a cutting blade configured to cut a trailing edge of the outgoing web; a web speed sensor sensing the speed of the outgoing web as it moves through the plurality of rollers; a leading edge sensor sensing a location of a leading edge of the replacement web; a first splicer sensor sensing a location of a first adhesive strip; a second splicer sensor sensing a location of a second adhesive strip; and a controller receiving data from the web speed sensor, leading edge sensor, and splicer sensor, the controller further receiving an initiate splice signal; wherein, upon receiving the initiate splice signal, the controller operates the plurality of rollers and cutting blade to form, using the first and second adhesive strips, a splice between the trailing edge of the outgoing web and the leading edge of the replacement web, wherein each of the first and second adhesive strips extends across the splice to contact both the trailing edge and the leading edge. - View Dependent Claims (16, 17, 18, 19, 20)
