Slider holder for application of double sliders to a slide fastener chain
 An apparatus for holding a pair of sliders for application to a slide fastener chain comprises, in combination with a plurality of angularly spaced slider supports intermettently movable successively through a slider receiving position and a slider applying position, an auxiliary slider support mounted on a frame of the apparatus and disposed in lateral alignment with one of the slider supports which has been brought into the slider applying position. The auxiliary slider support is reversible in position relatively to the one slider holder in such a manner that the distance between the one slider support and the auxiliary support varies upon reversal of the auxiliary slider support.
