摘要： PURPOSE:To provide a method for operating a directly weaving device capable of feeding perfect wefts to prevent the generation of defects of the woven fabric, even when storage drums are used. CONSTITUTION:A method for driving a directly weaving device in which a weft-processing machine 5 having storage drums 15 is connected to a loom 1 for feeding wefts is characterized by controlling the driving of the storage drums 15 in connection with the driving of the weft-processing machine 5. In the method, imperfect wefts are passed through the storage drums 15 as waste fibers as such and subsequently sucked into a waste fiber-removing pipe 46 until the weft-processing machine 5 is started and stably driven. After a prescribed time, the traveling wefts are wound up on the storage drums 15 as preliminary wound wefts, and subsequently the loom 1 is started at a time synchronous with the formation of the preliminary wound wefts.

摘要： PURPOSE:To improve cloth quality by taking off part of knotty conjugate yarn during a period from the time of starting a fluid jet treating device to normal operation with a yarn end treating device without winding the knotty conjugate yarn formed with the above-mentioned fluid jet treating device, then synchronously operating the aforementioned fluid jet treating device with a loom and carrying out smooth picking. CONSTITUTION:Two yarns respectively unwound from two bobbins 10 and 11 are fed to a fluid jetting nozzle 3 with overfeeding parts 1 and 2 by changing an overfeeding rate of either thereof and the formed knotty conjugate yarn is guided through a take-off roll 12 serving also as a weft yarn length measuring device without winding, further a weft yarn resident pipe 16 and a picking nozzle 14 to a yarn end treating device 4. Part of the knotty conjugate yarn during a period from the time of starting the fluid jetting nozzle 3 to normal operation is taken off with the above-mentioned yarn end treating device 4 and the aforementioned fluid jetting nozzle 3 is then synchronously operated with a loom to carry out smooth picking of the knotty conjugate yarn.

摘要： PROBLEM TO BE SOLVED: To obtain a characteristic change in a physical treatment, such as twisting treatment of multifiber yarn, from the characteristics of the raw yarn which are usually always recognized without requiring the actual measurement like in the conventional method. SOLUTION: The physical characteristics, such as size and strength and elongation of the multifiber yarn which is the assembly of plural pieces of single yarn in the physical treatment of the multifiber yarn, are obtd. in this method. At this time, the section of the multifiber yarn is divided to plural concentric annular layers of a prescribed thickness. The physical characteristics after the treatment for the single yarn in the respective layers are determined from the characteristics before the treatment of the single yarn by the operation expression for the change in the physical characteristics by the physical treatment of the single yarn. The physical characteristics of the respective layers are determined from the physical characteristics after the treatment of the resulted single yarn. The physical characteristics of the multifiber yarn are determined from the physical characteristics of the respective layers obtd. the manner described above.

摘要： PURPOSE:To impart a special alternating twist to a fiber by disposing a twisting device between two fiber-holding devices, disposing heat treatment devices on the upstream and downstream sides of the twisting device and intermittently feeding the fiber for each approximately same length thereof as the distance between both the fiber-holding devices. CONSTITUTION:A thermoplastic synthetic fiber 9 is intermittently fed into fiber- holding devices 3 and 4 for each approximately same length of the fiber as the distance between the fiber-holding devices 3 and 4. The fed fiber is twisted with the rotation power of the twisting device 1 and subsequently heat-set with heat treatment devices disposed on the upstream and downstream sides of the heat treatment device, thereby providing an alternating fiber having a S twist and a Z twist for each fixed length.
