ABSTRACT:
A device for guiding a concealed slide fastener to a sewing machine includes a pair of spaced track bodies mounted on a slanted guide plate and each comprising a block fixedly mounted on the guide plate and a cover member movably mounted on said block. The block and the cover member jointly define a guide channel for guiding an element assembly of the slide fastener therethrough while the slide fastener is fed down the guide plate toward a sewing position on the sewing machine. The guide channel includes a recess for accommodating coupling heads of the element assembly at an inlet end thereof, the recess being shaped for automatically erecting the element assembly from a horizontal position to a vertical position as the element assembly is moved progressively through the guide channel. The guide plate supports a means for sensing an end of the concealed slide fastener.
