ABSTRACT:
A stop fixing device for a slide fastener according to this invention generally comprises upper and lower levers, an elongated guide member defining a channel therein for slidably receiving a band of stops, a pivot for connecting the levers and the guide member for relative rotation and a punch mechanism including a punch guide channel communicated with the forward end of the channel in the guide member and a punch received in the punch guide channel. The punch guide channel has a width substantially equal to the distance between the shoulders of the stop and has a widened portion where it communicates with the channel of the guide member. Cam surfaces are provided at the lower end of the opposite side walls of the widened portion. A stop arrester is provided at the forward end of the guide member for preventing movement of the stop band in a vertical direction. A regulator plate is adjustably mounted on one of the levers to engage the other lever for controlling spread angle of the levers.
