摘要： PURPOSE: To provide the subject device designed to surely catch a weft inserted into a shed by a stretching nozzle mounted on the sley of a loom and a blower device set up in the vicinity of the stretching nozzle to effect sure picking through avoiding return of the weft to its insertion end. CONSTITUTION: This device for stretching a weft works as follows: for each weaving cycle, a weft 8 is inserted into a shed by the aid of airflow passing through a yarn carrying duct formed of the U-shaped recess of a read 2, concurrently a weft remaining end 11 is sucked into a yarn guide duct 17 by the actuation of a stretching nozzle 13 mounted on a sley 1 to effect picking; subsequently, the sley 1 is advanced, beating the weft 8 along a cloth line 9 and forcing it into a yarn clip 23, then the sley 1 is retreated, a warp 5 is crossed, to weave the weft 8. When the sley 1 is retreated, the actuation of the stretching nozzle 13 is stopped, concurrently a blower device 14 set up near the stretching nozzle 13 is set in motion and an airflow at an angle of 10-30 deg. in respect to the weft 8 is blown out to discharge the weft 8 from the yarn guide duct 17. The actuation of the blower device 14 is stopped prior to insertion of the succeeding weft 8.

摘要： PURPOSE: To improve and facilitate the cleaning of an airjet nozzle and a reed in a loom, and further to evade the fear of damaging of a loom member at the time of cleaning. CONSTITUTION: A cleaning liquid aiming the cleaning is supplied through airjet nozzles 40, 42 and 44 at a temporal interval in an airjet loom. For the purpose, magnetic valves 10 to 24 are allowed to have each one additional connecting member 46, and the airjet nozzles 40, 42 and 44 are allowed to be selectively connected to the source of the supply of the cleaning liquid through the connecting members 46.

摘要： PURPOSE: To retrieve yarn end on a yarn-feed spool by forming the device configuration from a means to generate an air stream, a means to put the whole surface of the yarn-feed spool in contact with the air stream, at least one suction hole to be coupled with one side of the spool, and a sendout device. CONSTITUTION: A yarn-feed spool 1 is mounted on a supporting table 2. A means 5 to generate an air stream consists of an impeller 11 supported by a shaft 10 driven by a motor 12 which uses a transmission device 13, and a means 6 to put the whole surface 7 of the yarn-feed spool 1 in contact with the air stream is composed of a bobbin support 14 rotating on the table 2 and a driving element 15 to work in coupling with the bobbin support. Installation is made with the dimensions of a suction hole 8 in such a way as positioned on the long shaft side of the spool 1 in the same manner as on the side with impeller 11. A means 9 to approach the suction hole 8 and air stream means 5 to the spool 1 is composed of the mentioned impeller 11, a support using an expansion arm 16 for suction hole 8, an arm 16 using a support 18 rotating round a shaft 17, and a carriage 21.

摘要： PURPOSE: To enable a restart of a weaving process in an extremely short period of time by joining a thread drawn out from a separate thread supply to an end part of a warp thread still attaching to a cloth after a warp break and restarting a loom by applying a tension of same strength as that to the other warp threads. CONSTITUTION: This method for carrying on weaving from a separate thread supply after a warp break comprises, on breaking a warp thread among many warp threads from a warp beam 1 to a cloth 8, joining a thread end part of the thread 11 drawn from a separate thread supply 12 and passing through a thread-drawing mechanism 13 to the thread end part of the warp thread still attaching to the cloth with a thread joining device 14 and imparting a tension of same strength as the tension applied to the other warp threads to the thread 11 by a thread-drawing mechanism 13.

摘要： PURPOSE: To provide the subject method comprising specially operating two thread nippers, a cutter, a special mechanism, a driving mechanism and a control unit, respectively, to enable a thread wound off a thread feeder to be automatically cut into pieces of a specified length. CONSTITUTION: This method comprises such a practice that, the free end of a thread 6 wound off a thread feeder 2 is held on a 1st nipper 3 and the vicinity of the free end is then held on a 2nd mobile nipper 4 followed by releasing the thread 6 from the 1st nipper 3; the 2nd nipper 4 is moved to further wind the thread 6 off the feeder 2; the thread 6 lying between the nipper 4 and the feeder 2 is operated by a mechanism 9, essentially a thread guide mechanism for further winding the thread 6 off the feeder, so as to bring the thread 6 lying between the mechanism 9 and the feeder 2 again toward the nipper 3 and a cutter 8 set up behind the nipper 3 with respect to the moving direction of the thread 6; and the thread 6 is then held on the nipper 3 again and cut into pieces of a specified length using the cutter 8.
