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.
