Abstract: A heald singularizing system includes a selecting member (21) for the healds (LI) fed in the form of a stack (LS). The selecting member (21) separates the front-most heald (LI1) from the stack and makes it available for the drawing-in of the warp threads. The selecting member (21) is formed by a piston which can perform a stroke essentially transversely to the heald stack (LS), during which the heald (LI1) is displaced from the heald stack (LS) into an intermediate position (ZP). Transfer means (24) transfers the respective heald (LI1) from its intermediate position (ZP) to a transport unit (25) for taking it to its drawing-in position. All types of healds can be selected from the heald stack, and neither a special preparation of the healds nor the use of a special type of heald is necessary. The heald separation and the further removal are completely uncoupled, to permit the use of means optimally adapted to the individual functions and also to simplify considerably the rectification of faults.

Abstract: A drawing-in machine for threading weaving machine harnesses is provided with apparatus for separating one at a time the drop-wires to be threaded from a stack of drop-wires. The stack of drop-wires is moved toward a stop located adjacent a slit. A selecting member (31) in the form of a friction wheel contacts the front face of the forwardmost drop-wire of the stack of drop-wires to urge that drop-wire transversely into the slit so as to separate that drop-wire from the stack. The selecting member moves the front drop-wire from the drop-wire stack into an intermediate position from which it can be separated completely from the stack and threaded with a warp thread. The drop-wires do not need to have any specific configuration at the point of application of the selecting member and they also do not need to be lined up or arranged in a specific manner. The friction wheel contacting the drop-wires at their front face is able to singularize all types of drop-wires.

Largely automatic feeding of the warp-thread drawing-in machine with drop wires is made possible by this device.

Abstract: A method and apparatus for carrying out an automatic drawing-in is provided including forming lengths of thread which are double folded. The thread is passed to a corresponding heddle and between corresponding dents of a reed. The threads are leased and placed under tension. Progressively, the various threads which are leased and under tension are moved away from the drawing-in location. Heddles are selected from a plurality of magazines and the heddles are positioned in a drawing-in attitude. The reed is positioned and the dents are spread for passage of the various threads. The warp threads are passed by moving the drawn-in heddles directly from the associated magazines to a heddle frame of a corresponding set of heddle frames. The heddles are always retained in a guide.

Abstract: The technical field of the present invention relates to an apparatus for automatically threading a warp through the eye of a heddle. In a conventional automatic warp threading apparatus, a drawing-in needle equipped with a hook is delivered out through the eye and is pulled back after hooking the warp so as to thread the warp through the eye. For this reason, the eye is likely to be damaged and a defect is likely to occur during weaving. The automatic warp threading apparatus of the present invention warp threading apparatus of the present invention clamps the warp (Y) with finger members (18, 18') disposed on a thread feeder (5) and a jet nozzle (20) fitted to the finger members (18, 18') ejects a gas so as to thread the clamped warp (Y) through the eye. Accordingly, the eye is not damaged and weaving can be made advantageously.

Abstract: The device for repairing a yarn break includes a folder blade which is to be inserted between the warp yarns adjacent a broken yarn. During horizontal motion, the folder blade has two wings which diverge outwardly for spreading out the warp yarn. The folder blade also has a longitudinal groove to receive a heddle in the narrowest place between the wings. A sensor on one wing first determines the position of the heddle in the warp direction and generates a signal so that the folder blade comes to a stop with the heddle in the groove of the blade. A separate warp yarn can then be threaded into the heddle by drawing-in tubes.

Abstract: For pinning of drop wires for the mechanical drawing-in of warp threads, the keyholes thereof located at different distances from the thread eyes in two different types of drop wires must be aligned with one another for the reception of a pinning rod. Both types of drop wires are thus strung onto a lease rod which passes through the thread eyes of both types of drop wires, the lease rod having a T-shaped cross-section at one end segment and a rectangular cross-section at an opposite end segment with an intermediate gradual transition of increasing thickness of the T-crossbar portion of the T-shaped cross-section. The thread eye of one type drop wire has a cutout defining opposed projections engaging upper surfaces of the T-crossbar, and the drop wires of the other drop wire type which are not intended to be displaced have an upper thread eye portion which is of essentially the same size and shape as the rectangular-sectioned segment of the lease rod.

Abstract: Several draw-in needles are arranged in parallel in a warp thread draw-in device. The draw-in needles can be coupled selectively individually or in combination to an advanceable carriage. When the carriage is advanced, only the selected and coupled draw-in needles are carried along whereby the draw-in procedure is carried out simultaneously. The selection of the draw-in needles as a function of the desired patterning can be implemented automatically by a program control.
