Abstract

A fastener arrangement includes a first fastener member having a base sheet and a plurality of engaging members projecting from the base sheet. The fastener arrangement includes a layer of pressure sensitive adhesive on a surface of a base sheet opposite of the engaging members, and a dual purpose cover sheet. The dual purpose cover sheet protects the adhesive layer of the first fastener member, and the engaging members of a second, underlying fastener member. The dual purpose cover is releasably attached to the second fastener member by fusing or by using an adhesive having a first non-tacky consistency and a second tacky consistency.

Claims

1. A method of providing a fastener arrangement, comprising:

a) providing a first fastener member, including a base sheet having first and second major surfaces, and a plurality of engaging members adjoining and projecting from the first major surface;

b) providing a dual purpose cover sheet having first and second major surfaces;

c) attaching selected portions of the first major surface of the cover sheet with selected portions of the first fastener member such that the first major surface of the cover sheet is releasably affixed to the first fastener member;

d) providing a second fastener member including a base sheet having first and second major surfaces, a plurality of engaging members adjoining and projecting from the first major surface, and an adhesive layer disposed on the second major surface; and

e) releasably affixing the adhesive layer of the second fastener member to the second major surface of the cover sheet.

2. The method of claim 1, wherein step (c) includes fusing selected portions of the first major surface of the cover sheet with selected portions of the first fastener member.

3. The method of claim 1, wherein step (c) includes providing a series of sonic bonds which utilize high frequency energy to fuse the selected engaging members to selected portions of the cover sheet.

4. The method of claim 1, wherein selected portions of the cover sheet are releasably affixed to the base sheet of the first fastener member.

5. The method of claim 1, wherein selected portions of the cover sheet are releasably affixed to the engaging members of the first fastener member.

6. The method of claim 1, wherein the dual purpose cover sheet has a first side and a second side, and wherein step (c) includes providing a first series of fuse patterns adjacent the first side of the cover sheet and second series of fuse patterns adjacent the second side of the cover sheet.

7. The method of claim 1, wherein the adhesive layer is a layer of pressure sensitive adhesive.

8. A method of providing a fastener arrangement, comprising:

a) providing a first fastener member, including a base sheet having first and second major surfaces, and a plurality of engaging members adjoining and projecting from the first major surface;

b) providing a dual purpose cover sheet having first and second major surfaces;

c) providing means for releasably affixing the first major surface of the cover sheet to the first fastener member;

d) providing a second fastener member, including a base sheet having first and second major surfaces, a plurality of engaging members adjoining and projecting from the first major surface, and an adhesive layer disposed on the second major surface; and

e) releasably affixing the adhesive layer of the second fastener member to the second major surface of the cover sheet.

9. The method of claim 8, wherein the means for releasably affixing the cover sheet to the first fastener member includes an adhesive disposed on the first major surface of the cover sheet, the adhesive being adapted for transition from a non-tacky state to a tacky state when heated.

10. The method of claim 9, further comprising the steps of heating the cover sheet so that the first adhesive becomes tacky;

and engaging the cover sheet to the engaging members while the adhesive is tacky.

11. The method of claim 9, wherein the adhesive is dot coated on the first major surface.

12. The method of claim 8, wherein the adhesive layer is a layer of pressure sensitive adhesive.
