Abstract
Adhesive tape for the flying splice in paper finishing machines or the like having a paper backing and a water-soluble self-adhesive composition, the paper backing (2) being coated on one side with a water-soluble self-adhesive composition (3), and an edge region of the reverse face of the paper backing (2) being equipped with a double-sided adhesive tape (6) which in turn has a readily splicing paper backing (7) which is equipped on both sides with water-soluble self-adhesive composition (8 or 9) and, in addition, the other edge region of the reverse face of the paper backing (2) being equipped with a narrow strip of a double-sided adhesive tape (14) which in turn has a readily splicing paper backing (15) which is equipped on both sides with water-soluble self-adhesive composition (16 or 17).
Claims10
An adhesive splicing tape comprising:
- a) a paper backing having first and second faces and comprising a first water-soluble self-adhesive adhered to the first face;
- b) a first double-sided adhesive tape adhered to said paper backing on said second face, said first double-sided adhesive tape comprising a first cleavable backing and second and third water-soluble self-adhesives adhered to opposite sides of said first cleavable backing;
- and
- c) a second double-sided adhesive tape adhered to said paper backing on said second face, said second double-sided adhesive tape comprising a second cleavable backing and fourth and fifth water-soluble self-adhesive adhered to opposite sides of said second cleavable backing;
- wherein said first, second, third, fourth and fifth water-soluble self-adhesives may be the same or different;
- and
- whereby said first and second cleavable backings, when the adhesive splicing tape is adhered between a new paper reel and an old paper reel to be replaced by said new paper reel, both of which are in motion, will cleave in two portions between the water-soluble self-adhesives of said first and second double-sided adhesive tapes, such that portions of said first cleavable backing will continue to adhere to and cover said second and third water-soluble self-adhesives, and portions of said second cleavable backing will continue to adhere to and cover said fourth and fifth water-soluble self-adhesives.
