An improved shed forming device having two-part heald holders the parts of which are secured together by a quickly detachable connecting means. The means connecting the two portions of the holder is made as a locking means in which the extremity of one portion of the holder is inserted or telescoped into the other portion and is held in the inserted position by a selectively releasable pawl. With the heald holders of the invention, warp threads may be drawn into the healds, when changing the weaving design or the number of healds in the individual holders, outside and away from the loom; thus reducing the idle time of the loom to a minimum. With the locking means there is preferably provided means for unlocking the pawl and for shifting the two portions of the holder relative to each other. The device of the invention may incorporate a cursor running or guide means extending across the loom, the cursor selectively locking the two portions of successive holders together or unlocking them from each other.
In a travelling-wave shedding loom having a shed forming device comprising heald holders arranged side-by-side in arrays across the warp sheet, and a mechanism for reciprocating and controlling the heald holders, the improvement wherein the upper portion of each holder supports the healds and the lower portion of each holder is drivingly connected with the heald reciprocating mechanism, each said heald holder comprising two separate members which are connected to each other in the loom, a lock for selectively connecting the two members of the holder, said lock comprising one portion of one member of the holder which is formed so that one end thereof may be telescoped into a mating portion of the other member, and a pawl for selectively holding the members in telescoped connected position.
