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.
A method for forming a precursor web for manufacturing a fastener, particularly a male fastener for a hook and loop fastening system, comprising:
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.
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.
