Abstract:
A method of forming a coreless roll of pressure sensitive adhesive tape comprising the steps of:providing a first rotating winding mandrel in a first winding station; directing a leading edge of an advancing strip of pressure sensitive adhesive tape around and directly against the first mandrel; winding the tape successively upon itself and the first mandrel to form an in-process coreless tape roll; advancing the first mandrel and in-process coreless tape roll thereon to a second transfer station while advancing a second rotating mandrel into the first winding station for engagement with the advancing tape; severing the tape between the first and second mandrels to define a trailing edge of the tape wound upon the first mandrel; winding the tape on the first mandrel in the second transfer station until the trailing edge is wound thereon to form a completed coreless tape roll on the first mandrel; and prior to the directing step, applying a liner/tab along a portion of the strip of pressure sensitive tape, on a side of the tape bearing adhesive, wherein the tape severing step cuts through that portion of the tape bearing the liner/tab so that a segment of the liner/tab masks a section of the adhesive adjacent the trailing edge of the tape wound upon the first mandrel.
