Title: Method of and apparatus for sorting slide fastener
Inventor: OKADA YOJO
IPC: A44B19/42
Filed: 1984-08-09
Granted: 1986-04-09
Abstract: In the method, slide fastners(F) are fed longitudinally one at a time along a path by at least one stream of air flowing along the path, and then introduced into a clearance or gate which is narrow enough to prevent the passage of sliders(S). Thus, when the slide fasteners have their respective sliders, they are stopped at the gate. When the slide fasteners have no sliders, they are allowed to pass through the gate and are further advanced by the stream of air. Thus, the slide fasteners are automatically sorted or separated into two groups according to the existence of the sliders. The stream of air is then interrupted so that the slide fasteners stopped at the gate are allowed to fall from the path into a container disposed below the gate.
