Molding fastener elements on folded substrate
摘要:
A method for forming a fastener product includes folding a sheet material about a longitudinal fold line to form a longitudinal edge portion overlapping only an adjacent portion of the sheet material, leaving another portion of the sheet material exposed as a remainder portion. The folded sheet material is continuously introduced to a gap adjacent to a surface of a rotating mold roll. Moldable resin is introduced between the sheet material and the mold roll to fill fixed cavities in the rotating mold roll to form portions of the fastener elements as stems bonded to one of the overlapping edge portion and the remainder portion. Additional material is bonded to the other of the overlapping edge portion and the remainder portion with the bonding occurring in the gap. The resin is solidified, then, stripped from the surface of the mold roll by pulling the stems from their respective cavities.
