Abstract

Herein is disclosed a device and method for attaching a tab to an elongate length of double-sided adhesive tape, the tab protruding beyond a terminal end of the elongate length of tape and being attached to both surfaces of the adhesive tape.

Claims

1. A dispenser comprising:

a frame;

a roll of double-sided adhesive tape positioned on the frame, the roll of tape having a terminal end;

a tab piece storage and attachment unit arranged on the frame, the unit having an elongated shape with first and second ends and comprising at least first and second major opposing walls extending at least partially between the first and second ends, the unit further comprising a plurality of individual tab pieces in a stack comprising first and second opposed major surfaces, wherein the tab piece stack is arranged between the first and second major opposing walls,

wherein the first major opposing wall contains a window that is proximate the first end of the tab piece storage and attachment unit and that exposes at least a portion of the first major surface of the tab piece stack,

wherein the first major opposing wall further comprises a non-window portion located between the window and the second end of the elongated tab piece storage and attachment unit; and

,

wherein the tab piece storage and attachment unit and the roll of tape are arranged such that when the terminal end of the tape is positioned in overlapping relation with the window, the tape is not in overlapping relation with the non-window portion of the first major opposing wall of the tab piece storage and attachment unit; and

wherein the dispenser is configured so that when a terminal end of the elongate length of double-sided adhesive tape is positioned in overlapping relation with the window, no portion of the tape is in overlapping relation with any portion of the tab piece stack other than the portion of the tape that is in overlapping relation with the window.

2. The dispenser of claim 1 wherein the window comprises a leading edge and a trailing edge, and further wherein the tab piece storage and attachment unit comprises an end stop positioned at the trailing edge of the window.

3. The dispenser of claim 1 wherein the window comprises first and second side edges, and further wherein the tab piece storage and attachment unit comprises at least one alignment rail positioned along a side edge of the window.

4. The dispenser of claim 3 wherein the tab piece storage and attachment unit comprises a first alignment rail positioned along the first side edge of the window and a second alignment rail positioned along the second side edge of the window, and wherein both rails extend beyond the first major opposing wall of the tab piece storage and attachment unit.

5. The dispenser of claim 1 wherein the window comprises a leading edge and a trailing edge, wherein the tab piece storage and attachment unit comprises a flange positioned at the leading edge of the window, and wherein the flange is in overlapping relation with a portion of the first major surface of the tab stack.

6. The dispenser of claim 1 wherein the window comprises a leading edge, a trailing edge, and first and second side edges, and further wherein the tab piece storage and attachment unit comprises a flange positioned at the leading edge of the window, at least one alignment rail positioned along a side edge of the window, and an end stop positioned at the trailing edge of the window.

7. The dispenser of claim 1 wherein the second major wall of the tab piece storage and attachment unit comprises a biasing element arranged to press against the second major surface of the tab piece stack.

8. The dispenser of claim 1 wherein the frame comprises a tape hub with an axis, and wherein the elongated tab piece storage and attachment unit is arranged such that:

the longitudinal axis of the elongated unit is oriented substantially parallel to the axis of the tape hub;

the first and second major opposing walls of the tab piece storage and attachment unit are substantially parallel to each other; and

,

the first major opposing wall is positioned closer to the tape hub and the second major opposing wall is positioned further from the tape hub.

9. The dispenser of claim 1 further comprising a cutting device arranged on the frame.

10. A device for attaching a protruding tab to a terminal end of an elongate length of double-sided adhesive tape, the device comprising:

a tab piece storage and attachment unit containing a plurality of individual tab pieces arranged in a stack with first and second major surfaces, the tab piece storage and attachment unit having an elongated shape with first and second ends and comprising at least first and second major opposing walls extending at least partially between the first and second ends,

wherein the first major opposing wall comprises a window that exposes at least a portion of the first major surface of the tab piece stack, the window defined on all sides by edges, wherein the edges comprise leading and trailing edges that are oriented substantially transversely to the longitudinal axis of the elongated unit, and first and second side edges that are oriented substantially parallel to the longitudinal axis of the elongated unit;

wherein the tab piece storage and attachment unit comprises a flange positioned at the leading edge of the window, wherein the flange is in overlapping relation with a portion of the first major surface of the tab piece stack; and

,

wherein the tab piece storage and attachment unit is attached to the frame of a double-sided adhesive tape dispenser that is configured so that when a terminal end of the elongate length of double-sided adhesive tape is positioned in overlapping relation with the window, no portion of the tape is in overlapping relation with any portion of the tab piece stack other than the portion of the tape that is in overlapping relation with the window.

11. The device of claim 10 wherein the tab piece storage and attachment unit comprises an end stop positioned at the trailing edge of the window.

12. The device of claim 10 wherein the tab piece storage and attachment unit comprises at least one alignment rail positioned along a side edge of the window.

13. The device of claim 12 wherein the tab piece storage and attachment unit comprises a first alignment rail positioned along the first side edge of the window and a second alignment rail positioned along the second side edge of the window, and wherein both rails extend beyond the first major opposing wall of the tab piece storage and attachment unit.

14. The device of claim 10 wherein at least a portion of the first major wall of the tab piece storage and attachment unit comprises a biasing element arranged to press against the second major surface of the tab piece stack.

15. The device of claim 14 wherein the biasing element comprises a leaf spring.

16. The device of claim 10 wherein the tab piece storage and attachment unit comprises at least one alignment rail positioned along a side edge of the window, and an end stop positioned at the trailing edge of the window.

17. The device of claim 10 further comprising a cutting device arranged on the frame.
