ABSTRACT:
A method of and an apparatus for assembling a slide fastener slider by fitting together a slider body having an attachment lug provided on the upper surface thereof and a pull tab having an aperture in the one end thereof. There is a large enough gap between a distal end of the attachment lug and the upper surface of the slider body to allow the distal end to pass through the aperture of the pull tab. The method is characterized by gradually pressing the distal end of the attachment lug toward the slider body as the slider body is transported along the transport path by using feed rollers having combined functions to constitute a die and to transport the slider body thereon as well as a punch roller.
