  • Patent number: 4499638
    Abstract: In a device for individually separating heddles and to subsequently draw-in warp threads into the heddle eyes using advancing and retracting needles, the heddles require being moved into a precisely defined position of draw-in. Rest means with a serrated profile are provided, which receive the individually separated heddle by means of a pressing finger in such a manner that the heddle rests against one of the ramps of the sawtooth profile. The heddle is so rotated in the process that the aperture of the heddle eye is placed in a precisely defined position and furthermore practically transversely to the path of the draw-in needle. The drawing-in of the warp threads is thereby made substantially simpler and more reliable.
