Abstract

De-collatable bindings and methods of producing the same are disclosed. A disclosed includes a cover defining a spine and signatures disposed within the cover. The disclosed also includes a low tack adhesive disposed between the spine of the cover and the signatures to facilitate removal of the signatures from the cover.

First claim

What is claimed is:

1. A method comprising:
applying first and second removable adhesive patterns to one or more of a cover or signatures, the cover defining an interior spine, the signatures including first and second signatures;
coupling the first signature to the interior spine via the first removable adhesive pattern, the first signature having a first backbone, wherein the first signature includes a first ribbon and a second ribbon, and wherein the first ribbon is disposed in the second ribbon such that the second ribbon forms the first backbone;
coupling the second signature to the interior spine via the second removable adhesive pattern, the second signature having a second backbone, wherein the second signature includes a third ribbon and a fourth ribbon, and wherein the third ribbon is disposed within the fourth ribbon such that the fourth ribbon forms the second backbone; and
coupling the first ribbon to the second ribbon via a third removable adhesive pattern, wherein the first removable adhesive pattern has a first surface area and the third removable adhesive pattern has a second surface area, the second surface area smaller than the first surface area.

2. The method as defined in claim 1 , further including assembling a retention tab to opposing ends of the cover to retain the first and second signatures within the cover.

3. The method as defined in claim 1 , wherein applying the first and second removable adhesive patterns includes placing the first and second removable adhesive patterns along only a portion of a length of the first and second signatures.

4. The method as defined in claim 1 , further including trimming the cover and the first and second signatures simultaneously.

5. A book comprising:
a cover defining a spine;
a first signature having a first backbone, the first signature disposed within the cover, wherein the first signature includes a first ribbon and a second ribbon, and wherein the first ribbon is disposed in the second ribbon such that the second ribbon forms the first backbone;
a first removable adhesive pattern disposed between the first backbone and the spine;
a second signature having a second backbone, the second signature disposed within the cover, wherein the second signature includes a third ribbon and a fourth ribbon, and wherein the third ribbon is disposed within the fourth ribbon such that the fourth ribbon forms the second backbone;
a second removable adhesive pattern disposed between the second backbone and the spine; and
a third removable adhesive pattern to couple the first ribbon to the second ribbon, wherein the first removable adhesive pattern has a first surface area and the third removable adhesive pattern has a second surface area, the second surface area smaller than the first surface area.

6. The book of claim 5 , further comprising a retention tab coupled to opposing ends of the cover to retain the signatures within the cover.

7. The book of claim 5 , wherein upon removal of the first signature, the first adhesive pattern decouples from the first signature and remains disposed on the spine.

8. The book of claim 5 , wherein the first and second adhesive patterns are applied to the first and second backbones of the first and second signatures, respectively, prior to disposition of the first and second signatures within the cover.

9. The book of claim 5 , wherein the first and second adhesive patterns are applied to only a partial length of the first and second backbones of the first and second signatures, respectively.

10. The book of claim 9 , wherein the partial length is a central portion of the first and second signatures.

11. The book of claim 5 , wherein the cover includes a first leg and a second leg, the spine formed between the first leg and the second leg, a portion of the second ribbon releasable adhered to the first leg, and a portion of the fourth ribbon releasable adhered to the second leg.

12. The book of claim 5 , wherein the first ribbon remains coupled to the second ribbon when removed from the cover.

13. The book of claim 5 , wherein the first and second removable adhesive patterns are to be applied between a first point at a first distance from a leading edge of the first and second signatures to a second point at a second distance from a trailing edge of the first and second signatures.

14. The book of claim 5 , wherein the first and second removable adhesive patterns are applied to the first and second signatures, respectively, based on a ramped application profile proximate the first and second points.

15. The book of claim 5 , wherein the first and second removable adhesive patterns are applied to the first and second signatures, respectively, based on at least one of a curved or parabolic application profile proximate the first and second points.

16. The book of claim 5 , wherein the first and second removable adhesive patterns are centered between the trailing edge and the leading edge of the first and second signatures.

17. The book of claim 5 , further including a fourth adhesive pattern, wherein the fourth adhesive pattern is disposed between a third point at a third distance from the leading edge of the first and second signatures to a fourth point at a fourth distance from the trailing edge of the first and second signatures.

18. The book of claim 5 , wherein the first and second removable adhesive patterns overlap.

19. The book of claim 5 , wherein the first and second removable adhesive patterns are coextensive.
