Abstract

A transfer mechanism is shown for placing a double-sided adhesive strip to the end of a web of material, such as magnetic tape, for holding the tape to a real hub. The adhesive is supplied as small pieces on a liner paper. The end of the tape is held flat by a vacuum plate, while a pressure roll places the adhesive onto the end of the tape. The vacuum plate is then advanced toward the hub to place the end of the tape onto the hub. As shown in the figure, small pieces of an adhesive 1 of a double-coated adhesive is fastened on one side to a liner paper 2 with one side of the adhesive being uncovered. The liner paper 2 and the adhesive pieces 1 are directed from a supply reel 3 past idler rolls 4 and 5 over a pressure roll 6 onto a third idler roll 7 and onto a takeup roll 8.

Adhesive Transfer Mechanism

A transfer mechanism is shown for placing a double-sided adhesive strip to the end of a web of material, such as magnetic tape, for holding the tape to a real hub. The adhesive is supplied as small pieces on a liner paper. The end of the tape is held flat by a vacuum plate, while a pressure roll places the adhesive onto the end of the tape. The vacuum plate is then advanced toward the hub to place the end of the tape onto the hub. As shown in the figure, small pieces of an adhesive 1 of a double-coated adhesive is fastened on one side to a liner paper 2 with one side of the adhesive being uncovered. The liner paper 2 and the adhesive pieces 1 are directed from a supply reel 3 past idler rolls 4 and 5 over a pressure roll 6 onto a third idler roll 7 and onto a takeup roll 8. Two motions are provided in the adhesive transfer mechanism. First is the advance and retraction of the pressure roll 6, and the second is the indexing and advancing of the supply roll 3 and the takeup roll 8 to place new pieces of adhesive 1 into position. The pressure roll 6 is fastened to a transfer arm 9 which is pivoted at point 10 and moves in a linear direction, as shown by the dotted line of the pressure roll 6 and the liner paper 2. A spring 11 holds the transfer arm against a vacuum plate 12. Vacuum plate 12 is pivoted at point 13 and includes a compression spring 14 to press the vacuum plate 12 against the pressure roll 6. The magnetic medium in the form...
