Abstract
Slide fasteners are fed longitudinally one at a time along a path by at least one stream of air flowing along the path, and are then introduced into a clearance or gate which is narrow enough to prevent the passage of sliders so that when the slide fasteners have respective sliders, they are stopped at the gate, while when the slide fasteners have no sliders, they are allowed to pass through the gate and be further advanced by the stream of air. Thus the slide fasteners are automatically sorted or separated into two groups according to the presence of the sliders. Thereafter, the stream of air is interrupted whereupon the slide fasteners stopped at the gate are allowed to fall from the path into a container disposed below the gate. The slide fasteners thus fallen are disposed in the container in juxtaposition.
