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.
Claims21
A fastener arrangement, comprising:
- a first fastener member including a base sheet having a first major surface, and a plurality of engaging members adjoining and projecting from the first major surface;
- a dual purpose cover sheet having first and second major surfaces, the first major surface including means for releasably affixing said cover sheet to the first fastener member including an adhesive coated on said first major surface of said cover sheet, said adhesive transitioning from a first non-tacky state at a first temperature to a second tacky state at a second, higher temperature to releasably affix said cover sheet to the first fastener member;
- and
- a second fastener member overlying said first fastener member, the second fastener member including a base sheet having first and second major surfaces, a multiplicity of engaging members adjoining and projecting from the first major surface;
- and an adhesive layer disposed on the second major surface of said base sheet, such that said adhesive layer releasably affixes the second fastener member to the second major surface of said cover sheet.
