Abstract
An elongate transfer tape includes a water-resistant removable top and bottom liner with two adhesive strips, one water soluble, the other water resistant, side-by-side in a plane between the liners. Above the water resistant adhesive is a water absorbent pad that when forced against paper will weaken the paper by the forced expulsion of water from the pad. The paper will attach to the tape and be drawn to a collecting spool to which the tape is attached. The paper will break along its weakened portion. The pad is constructed to hold water against the centrifugal forces that derive from the rotating collecting spool to which it is attached via the water resistant adhesive.
Claims20
Transfer tape for severing a traveling web of paper and transferring it to an empty spool comprising an elongate planar adhesive member having an outer surface bindable to a traveling web of paper and an inner surface bindable to an empty spool, said adhesive member extending substantially along a length of a spool upon which a web of paper is to be transferred and wound, and an elongate water-absorbent weakening means carried by said outer surface of said adhesive member for absorbing water and engaging a web of paper as an empty spool carrying said transfer tape rotatably engages a paper web, said weakening means carrying water so that said weakening means weakens a paper web upon engagement therewith.
An improved method for severing a traveling web of paper being wound on a spool and transferring the web of paper after severing to an empty spool, the method including an elongate tape having opposed side respectively attachable to an empty spool and attachable to a web of paper for winding the severed web of paper onto the empty spool, wherein the improvement comprises the steps of:
- A. applying a first adhesive to a portion of the surface of one side of the tape that is bindable to the surface of an empty spool;
- B. applying a second adhesive to a portion of the surface of the other side of the tape that is bindable to the web of paper;
- C. attaching a width of water-absorbent compressible element onto the other side of the tape and adjacent an edge thereof;
- D. attaching the tape to the spool with the first adhesive;
- E. applying water to the element attached in step C;
- F. positioning the empty spool to place the element and the other side of the tape into contact with the traveling web of paper to compress the element for weakening the paper along a portion thereof in contact with the element by expelling water absorbed by the element in step E into the paper and to adhere the paper to the second adhesive;
- G. severing the traveling web of paper along the weakened portion of the paper;
- and
- H. winding the severed web of paper onto the empty spool.
A method for severing a traveling web of paper being wound on a spool and transferring the web of paper after severing to an empty spool comprising the steps of:
- A. providing an elongate tape carrying a water-absorbent elongate portion and having opposed sides repectively attachable to an empty spool and attachable to a web of paper;
- B. adhesively attaching one side of the tape to an empty spool with the elongate portion being disposed outwardly of the empty spool;
- C. spraying the outer surface of the elongate portion with water so that the same is capable of weakening a traveling web of paper along its width thereof;
- D. contacting the empty spool with the traveling web of paper so that water is expelled from the elongate portion into the web of paper to weaken same and to adhere the traveling web downstream from the weakened portion of the web of paper to the empty spool;
- and
- E. rotating the empty spool to change the direction of the traveling web of paper to cause severing thereof along the weakened portion.
