Automatic lapless butt material splice

(57) 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.

Claims (20)

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.
The web splicer of claim 1, further comprising a motor communicably coupled to the splicer roller and configured to accelerate the splicer roller to a speed matching the speed of the outgoing web moving across the splicer backup roller.
The web splicer of claim 1, further comprising a pneumatic cylinder or a motor, the pneumatic cylinder or motor configured to actuate movement of the cutting blade toward the outgoing web.
The web splicer of claim 1, further comprising a pneumatic cylinder or a motor, the pneumatic cylinder or motor configured to actuate movement of at least one of the splicer roller and the splicer backup roller, so as to bring the splicer roller and splicer backup roller proximate to one another to press the second adhesive surface against the leading edge of the replacement web and the trailing edge of the outgoing web.
The web splicer of claim 1, further comprising a device for tracking the leading edge of the replacement roll.
The web splicer of claim 5, wherein the device comprises a leading edge marker arranged on the replacement roll and having a known relationship to the leading edge.
The web splicer of claim 1, further comprising a device for tracking the location of the second adhesive strip.
The web splicer of claim 1, wherein the web splicer is configured to form a lapless splice between the outgoing web and the replacement web.
The web splicer of claim 1, wherein the web splicer is configured to transition from a first configuration, with the replacement roll in a first position, to a second configuration, with the replacement roll in a second position.
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.

Description

The present application is generally directed to converting and printing machinery. Particularly, the present application relates to devices and systems for splicing rolls or webs of material. More particularly, the present application relates to devices and systems for creating a lapless butt material splice.

The background description provided herein is for the purpose of generally presenting the context of the disclosure. Work of the presently named inventors, to the extent it is described in this background section, as well as aspects of the description that may not otherwise qualify as prior art at the time of filing, are neither expressly nor impliedly admitted as prior art against the present disclosure.

Converting and printing machinery may include winders and unwinders. In a winder, an incoming web of material is wound onto a roll until the roll is filled. In an unwinder, a roll feeds an outgoing web of material. During unwinding, when a feeding roll is depleted or near depletion, a filled roll may replace the depleted roll and continue feeding the outgoing web material. Filled rolls of web material, such as for example newsprint, are typically large and heavy, weighing as much as several tons. Difficulties can arise with the transfer of the feeding source from one roll to the next.

It is common to splice the trailing edge of the depleted roll of material to the leading edge of the next roll of material to allow for generally continuous operation of the converting process. This splicing can be performed in various ways.
