ABSTRACT OF THE DISCLOSURE An apparatus for applying pieces of reinforcing film of synthetic resin to a pair of continuous slide fastener stringers at longitudinally spaced locations thereof, com- prises means for feeding the stringers longitudinally along a first path selectively at a rapid rate or a slow rate, means for sensing one of the locations on the stringers at a time to switch the feeding means from a rapid rate to a slow rate mode of operation and then to a stopping mode, and for locating said one of the locations on the stringers in a position for the application of one of the pieces of reinforcing film, and means for holding the stringers during the film-piece application. The apparatus also comprises means for intermittently feeding an elongate web of reinforc- ing film longitudinally along a second path extending transversely to the first path, means for holding a distal end of the elongate web which has passed across the first path, means for guiding the elongate web toward the holding means, means for successively forming the pieces of reinforc- ing film one at a time from the elongate web and means for applying said one of the pieces of reinforcing film to the stringers at said one of the locations thereof while the stringers are at rest.
