Abstract: A warp is prepared including a stationary thread, a crossing thread and an auxiliary thread, the latter two of which are laterally interlaced at a sliding connection and subject to being alternately tensioned and released for causing the crossing thread to cross across the stationary thread, and cross back, as conventional loom equipment is manipulated to create a succession of sheds into which wefts are inserted to weave a cross-woven textile fabric. As the weaving is being accomplished, a separating element is provided to prevent the sliding connection of the crossing and auxiliary threads from sliding so far towards the reed as to become incorporated in the fabric. The stationary or auxiliary thread may actually be constituted by a metal or other non-textile element, which is pulled out of the fabric as the fabric, having been woven, is moved downstream on the loom.

Abstract: In a circular loom, displacement means engage on the inner partial heald (7) of a partial heald pair (6, 7) after each shedding motion in order to bring about the instantaneous lateral relative counter-displacement of the partial healds for the reciprocal displacement of the leno thread (51), extending lengthwise to the ground thread (50), two neighboring warp threads (50, 51), for the production of a leno fabric (6, 7). Furthermore, the warp threads of one partial heald of a partial heald pair are guided freely by thread guide means (24) to bring about the shedding, and, on the other partial heald, to bring about a side change.

Abstract: A shed-forming apparatus for doup weaves comprises for each warp thread pair a plate adapted to be pivoted back and forth and comprising on one side of its pivoting axis a bore for the passage of the stationary warp thread and on the opposite side of its pivoting axis slot for accommodating the wip thread. Two or more plates are connected to one another as well as to drive discs by bolts or the like positioned radially outwardly beyond the slot, the drive discs being in turn engaged by a drive rod of the shed-forming mechanism. The peripheral shape of the plates may be elliptical or ellipsoidal or it may be circular. The drive discs may also take the form of belt-driven cog wheels engaging matching teeth of a toothed belt connected to the drive means for the shed-forming plates.

Abstract: An easer bar for controlling the tension of the warp threads in a loom controlled by a positive action dobby for weaving leno type fabrics is directly controlled by and connected to the dobby.

Abstract: The crossing thread supply system has four bobbin pairs which are disposed on rotatable disk-shaped elements. Each bobbin pair is guided downwardly through a tube which rotates with a respective rotatable element in non-rotatable relative relation. The tube extends obliquely so that all of the tubes deliver the respective thread pairs to twisting disks located in a relatively narrow lane.
