In the apparatus for forming a space in and simultaneously fixing a stop to a fastener chain of this invention, a casing is provided with a tubular frame portion in which a punch holder having a space punch and a driver punch is received for sliding movement. This apparatus further includes a cutting punch between the driver punch and the inner wall of the tubular frame portion. When the punch holder descends, the cutting punch cuts a stop forming wire and forms the cut wire length into a stop preform in cooperation with an anvil. As the punch holder further descends, the driver punch drives the stop preform into the tapes of the chain and simultaneously the space punch forms a space in the chain. During this operation, the cutting punch rises relative to the punch holder so as not to damage the tapes. |
