A method and apparatus for producing element-free gaps or spaces in a continuous fastener chain. Means are provided for supporting a series of discrete fastener elements formed by die-casting a metal or injection-molding a plastics material and secured to a tape cord with their coupling heads faced upwardly, severing the fastener elements into halves at the coupling heads towards the cord and removing the severed elements completely from the cord without damage thereto. The severing operation is effected by a vertically movable cutter blade adapted to thrust centrally into the coupling heads toward the cord and is immediately followed by the removing operation wherein a pair of removers are moved downwardly to take the severed elements away from the cord when the supporting means are forced out of holding engagement with the fastener elements. |
