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.
In a heddle frame heddles each having at least one thread eye for the shed formation on a weaving machine carried out by a plurality of oscillatory heddle frames which support the heddles, each of the heddle frames having only a single heddle supporting member which is driven by the respective heddle frame thereof to form the shed, the supporting member having a first slide bar, each of the heddles comprising an elongated element attached to the supporting member at only one single end section of each said heddle, one longitudinal edge of each said element having a first groove-shaped opening at said one end section engageable with said first slide bar of the supporting member, said opening being sized slightly greater compared to the size of said first slide bar for thereby attaching said element to the supporting member with relatively little play, said opening being located a predetermined distance from said thread eye, said longitudinal edge of each said elongated element having a second groove-shaped opening spaced from said thread eye a distance greater than said predetermined distance, the supporting member having a second slide bar engageable by said second opening for further attaching said element to the supporting member at said one single end section.
