Abstract
A heddle is held at one single end section in a heddle frame having a single supporting member, the heddle being held by the provision of a groove-shaped opening to engage a slide bar of the supporting member with little play relative thereto. Another groove-shaped opening of the heddle at its one end section can be provided to engage an auxiliary slide bar on the supporting member with much more play relative thereto. The opposite, non-driven terminal end of the heddle is formed as a guide element to enable the automatic drawing-in of the warp threads. In addition, such guide element functions to line up the plurality of heddles present in the heddle shaft by the provision of a rod-shaped body which extends through aligned openings in the guide elements of the heddles, so as to prevent the heddles from shuttling back and forth in the weaving operation, and from mutually snagging at their terminal ends.
