Abstract
Abstract Disclosed is a novel process for splicing webs of pressure sensitive laminate material. When webs of pressure sensitive laminates are spliced by conventional methods and wound into rolls, the resultant splices must be located and removed when the roll is later converted into pressure sensitive products. The novel splice is achieved by eliminating the top tape used in a conventional splice and overlapping a face sheet of one laminate web over the other laminate web to join the webs. For many processes, this novel splice is printable and does not have to be edited out, and it is at least as strong as those made with tapes. Also disclosed is a novel spliced pressure sensitive laminate.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
192 words
A method of splicing a first pressure sensitive laminate to a second pressure sensitive laminate, wherein each pressure sensitive laminate comprises, from top to bottom, a face sheet, a coating of pressure sensitive adhesive permanently adhered to the face sheet, and a release liner, the method comprising: A. making a first cut through the entire thickness of the first laminate across its entire width; B. making a second cut through only the release liner of the first laminate across its entire width parallel to the first cut so as to leave a portion of the face sheet extending beyond the release liner; C. making a third cut through the entire thickness of the second laminate across its entire width so as to permit continuous abutment of the cut ends of the first and second release liners; D. butting together the cut ends of the first and second release liners in a continuous abutment across their entire widths; and E. pressing the part of the first face sheet which extends beyond the first release liner onto the top of the second face sheet to permanently adhere the first and second face sheets together.
Claim 2
Independent Claim
192 words
A method of splicing a first pressure sensitive laminate to a second pressure sensitive laminate, wherein each pressure sensitive laminate comprises, from top to bottom, a face sheet, a coating of pressure sensitive adhesive permanently adhered to the face sheet, and a release liner, the method comprising: A. making a first cut through the entire thickness of the first laminate across its entire width; B. making a second cut through only the release liner of the first laminate across its entire width parallel to the first cut so as to leave a portion of the face sheet extending beyond the release liner; C. making a third cut through the entire thickness of the second laminate across its entire width so as to permit continuous abutment of the cut ends of the first and second release liners; D. butting together the cut ends of the first and second release liners in a continuous abutment across their entire widths; and E. pressing the part of the first face sheet which extends beyond the first release liner onto the top of the second face sheet to permanently adhere the first and second face sheets together.
Claim 3
Dependent Claim
145 words
The method of claim 1, further comprising: F. making a fourth cut through only the second face sheet across its entire width parallel to the third cut so as to leave a portion of the second release ,liner extending beyond the second face sheet less than the amount which the first face sheet extends beyond the first release liner so that the first face sheet will overlap the second face sheet when the first and second release liners are butted together; G. adhering a strip of splicing tape to the bottom of the release liner which overlaps and holds together the butted ends of the first and second release liners; and H. applying detackifier material on top of the release liners at the abutment of their ends to prevent the face sheet from being permanently adhered to the adhesive on the tape beneath the abutment.
