Abstract
The invention relates to a weaving machine having plural heddle frames, into which heddles are threaded with a free floating characteristic or operational clearance onto thread rails. The heddles are arranged on the thread rails with the least possibility of movement and without a free floating capability during a portion of the heddle frame movement and with a free floating characteristic during the rest of the movement of the heddle frame to facilitate a self-alignment of the heddles with the warp threads. The free floating characteristic is initiated by periodically reducing the distance between the two thread rails.
