ABSTRACT:
The invention concerns a device for individually separating heddles bunched into packs and arranged on heddle slide rails, the lifting of individual heddles from the pack being implemented by suction nozzles and the heddles being moved into position for drawing-in the associated warp threads. A blow tube is provided to generate the suction effect and is angularly bent at its front end constructed as a blow nozzle. A small tube is so inserted into the wall of the angular bend that its part within the wall of the tube forms an ejector nozzle and its external end acts as a suction nozzle to lift individual heddles off a pack. The blow nozzle may be brought into line with the direction of advance of the heddles whereby a blast of air issuing from the blow nozzle effects the further motion of a lifted heddle following the drawing-in of the warp thread.
