ABSTRACT:
A method and apparatus for carrying out an automatic drawing-in is provided including forming lengths of thread which are double folded. The thread is passed to a corresponding heddle and between corresponding dents of a reed. The threads are leased and placed under tension. Progressively, the various threads which are leased and under tension are moved away from the drawing-in location. Heddles are selected from a plurality of magazines and the heddles are positioned in a drawing-in attitude. The reed is positioned and the dents are spread for passage of the various threads. The warp threads are passed by moving the drawn-in heddles directly from the associated magazines to a heddle frame of a corresponding set of heddle frames. The heddles are always retained in a guide.
