ABSTRACT:
A slide fastener overturning conveyer includes an elongate hollow rectangular guide member having a guide channel for the passage of a slide fastener, and air nozzles disposed adjacent to an inlet of the guide channel and directed toward an outlet of the guide channel. The guide member is rotatably movable about its longitudinal central axis through an angle of 180 degrees for overturning the slide fastener while the latter is received in the guide member. The air nozzles eject a compressed air to convey the overturned slide fastener. The angular movement of the guide member and the compressed-air ejection are controlled by a sensor provided for detecting leading and trailing ends of the slide fastener. The overturning conveyer thus constructed is relatively small and simple in construction and is effectively operative even when a slide fastener is relatively long.
