METHOD FOR MANUFACTURING FASTENERS AND PRECURSOR WEBS, A FASTENER AND A PRECURSOR WEB
First Claim
1. A method for forming a precursor web for manufacturing a fastener, particularly a male fastener for a hook and loop fastening system, comprising:
- providing a substrate web with a contact release surface;
providing a deposition device having a plurality of cavities;
providing a polymer material heated to a molten state;
filling said molten polymer material into said cavities;
depositing said molten polymer material from said cavities onto said contact release surface having a temperature below the softening or the melting temperature of said molten polymer material, thereby forming preform projections sitting on and projecting from the contact release surface to their corresponding terminal ends;
said preform projections being in contact with the contact release surface for a time sufficient to solidify completely, thereby forming a precursor web from which the preform projections are releasable;
removing the precursor web off the deposition device by winding up the precursor web onto a roll.

Abstract
The invention relates to a method for forming a fastener having fastener members (23, 63) wherein molten polymer material is deposited by a deposition device onto a contact release surface (7, 27, 32), thereby forming preform projections (20, 60), which contact the front surface (21) of a carrier (13, 62) with their terminal ends (22, 61) and bond to the carrier (13, 62). The carrier (13, 62) is removed with the preform projections (20, 60) attached, thereby separating the preform projections (20, 60) from the contact release surface (7, 27, 32) and forming fastening members (23, 63) projecting from the front surface (21) of the carrier (13, 62). The invention relates further to a method for manufacturing a precursor web (66) for manufacturing a fastener, a fastener web (91, 94,101) for engaging with a loop fabric and a precursor web (66) for manufacturing a fastener.

- 5. A fastener web for engaging with a loop fabric, comprising a carrier with a front surface, onto which a multiplicity of discrete polymeric fastening members is bonded in a repeating pattern, said fastening members having a terminal end with a top surface and an attached end, and having a mantle surface extending between the top surface and the attached end, the mantle surface at least partially tapering from the top surface to the attached end in the direction to the attached end.

8. A precursor web for manufacturing a fastener, particularly a male fastener for a hook and loop fastener, comprising a substrate web with a contact release surface, onto which a multiplicity of discrete preform projections formed out of a polymer material are releasably bonded in a repeating pattern, said preform projections having a terminal end with a top surface, an attached end and a mantle surface extending between the top surface and the attached end surface and being tapered from the attached end to the top surface.
