ABSTRACT:
A method of feeding an array of sliders one at a time for application onto a stringer chain is disclosed, which method comprises holding the array of slider linearly in a tilted position relative to a horizontal path of travel of the stringer chain so that the sliders can slide down smoothly by gravity, orienting a leading slider to lie flush with the horizontal path of the chain and transferring the leading slider over to a slider applying station. An apparatus is also disclosed for carrying this method into practice.
