摘要： PURPOSE:To specify the dents position corresponding to a broken warp yarn in case of stopping of a weaving machine due to yarn breakage during weaning by vertically displacing a normal warp yarn existing at a prescribed position in correlation to the broken warp yarn and detecting the position in the width direction of weaving. CONSTITUTION:When a weaving machine is stopped due to warp yarn breakage during weaving, a separation member 12 in a waiting state is moved in the width direction of weaving and stopped at a position in the neighborhood of the above-mentioned broken warp yarns 1a and 1b so as to control the movement of healds 5 in a heald frame 4 by a function of a controller based on a position signal of a dropper at a lower-position state. A normal warp yarn 1 existing at a prescribed position in correlation to the above-mentioned broken warp yarns 1a and 1b, i.e., an adjacent position on the left side, is simultaneously drawn upwards by an elevation member 13. A yarn sensor 22 is then moved in the width direction of weaving to detect the above- mentioned warp yarn 1 displaced upwards. The position of the yarn sensor 22 in the width direction of weaving at a point of time of the detection is detected as the position of the warp yarn 1, thus detecting the dents position corresponding to the broken yarns 1a and 1b.

摘要： PURPOSE: To repair a broken warp yarn in a weaving machine by alternately conducting feeding/receiving of a fresh warp yarn through a threading-in tube moving stepwise over a stop motion wire, a heddle, a reed, or the like, on a warp yarn path. CONSTITUTION: When a warp yarn is broken, a fresh warp yarn 1 is taken out from a spool 10' through a tube 73' and sent to a storage part 75 through an auxiliary tube 72' by clamping with a pair of rollers 74, further passed through a sensor 91, is advanced into a yarn piecing device 75, and the warp yarn sucked/separated from warp yarn 10 through a suction nozzle 81 is connected to a broken warp yarn. Successively, the pair of rollers 74 are reversed and the warp 1 is fed into threading-in tubes 71, 72 by blowing air into the auxiliary tube 72'. The threading-in tubes 71, 72 are moved stepwise over a stop motion wire 21, a heddle 31, a reed 4, a guide 60 on a warp yarn path, at the same time, feeding/receiving of the warp yarn is alternately conducted from one side toward the other side of the parts 21, 31, 4, 60, and the warp yarn is repaired.

摘要： PURPOSE:To highly accurately detect the breakage of a yarn, lighten the load of maintenance and installation and lower troubles because of not requiring any other device by recognizing the abnormal pattern of light quantity change in a knitting region between each reed and each knitting needle to detect the breakage of the yarn. CONSTITUTION:An optical axis between a light transmitter 1 and a light receiver 2 is set in a knitting region meaning a space between the reeds of a warp- knitting machine and the knitting needles thereof disposed below the reeds and is extended in parallel to a warp-arranging direction. Since the abnormal pattern of the change in the quantity of light in the knitting region between each reed and each knitting needle is recognized and the breakage of the yarn is detected, the breakage of the yarn is surely detected.

摘要： PURPOSE: To surely automatize a warp repairing operation by memorizing a harness, reed, selvage, a number of threads, warp characteristics, inputting information of position of fallen drop wire by broken warp to a control system, moving a reed space counting device to a fall position and stopping the device. CONSTITUTION: This apparatus is equipped with a memory for memorizing information on drawing-in of a harness of a weaving machine, reed characteristics, selvage, a number of threads and warp characteristics a receiver of numerical position data of a detection position in a row of drop wire of a fallen drop wire by broken warp and a transmitting set for inputting the position data to a computerized control system. The apparatus is further furnished with a moving reed space counting device which moves itself to a reed space at the location of a broken end of warp and stops directly opposite the reed space to automatically carry out the repairing operation of broken warp.

摘要： PURPOSE:To correctly locate threading part material by transferring warp adjoining to broken warp and enlarging interval of corresponding dents of a reed. CONSTITUTION:A threading tool 110 is supported by a belt wrapped between a pair of pulleys 111 movably in the direction of woven breadth. Interval of dents of broken warp or dents near the broken warp is enlarged and dents having wide interval is detected by a sensor 118 of the threading tool 110 opposed to reed 8, then the threading tool 110 is stopped at the detected position. The threading tool has a needle with hook for pulling a joined yarn and the joined yarn is tied with end part of warp, then the tied knot is introduced to heald or dents of reed.

摘要： PURPOSE: To provide the subject apparatus capable of dropping a dropper onto a bar prepared by combining a conductor and a resistor which are mutually insulated by warp yarn breakage, short-circuiting both, automatically stopping a frame by an output of a first DC power source and accurately digitally displaying a position of the warp yarn breakage with an output of a second DC power source. CONSTITUTION: This apparatus for detecting the warp yarn breakage of a loom is capable of dropping a dropper on a dropper bar prepared by combining a conductor and a resistor which are mutually insulated short-circuiting both, making an operating signal based on the output voltage of a first DC power source appear in the conductor, automatically stopping the loom through a loom control circuit, then dividing the output voltage of a second DC power source contained in a display circuit onto the resistor by the dropped dropper, providing a positional signal and accurately displaying a position for dropping the dropper, i.e., a yarn breakage position of the warp yarn through an analog to digital(AD) converter.
