ABSTRACT:
A method of feeding a continuous slide fastener chain with successive fly strips in a slide-fastener finishing machine, comprises feeding the slide fastener chain with successive fly strips along a horizontal straight path normally by applying driving force to one tape free of the fly strips, and feeding the slide fastener chain by applying the driving force to both of the opposed tapes while the slide fastener chain is threaded through a slider. An apparatus for carrying out this method comprises a main roller engageable with the lower surfaces of the opposed tapes, and first and second associate rollers engageable with the respective upper surfaces of the opposed tapes and vertically movable independently of each other.
