ABSTRACT:
A method and apparatus for attaching sliders and bottom stops to a slide fastener chain having longitudinally spaced gaps free of fastener elements, in which the chain is conveyed forwardly until a gap is detected. The chain is stopped and the gap area widened. A rotor movable beneath the chain is adapted to carry a slider and is also formed with a die plate portion. The rotor rotates to deliver the slider to the gap, thread the slider onto the fastener elements of the chain, and place the die plate beneath the gap across from bottom stop punch and chain cutter means which then fix a bottom stop to the chain and separate adjacent fastener element ends.
