摘要： A main nozzle for an air jet loom has an outer casing and is provided with a compressed air introduction duct and a mixing chamber. A mixer tube provided with an annular distributor ring is inserted into the outer casing to form with the outer casing and annular distribution chamber upstream of the distributor ring and, downstream of the distributor ring, and annular accceleration chamber which feeds into the mixing chamber. The distributor ring has annularly arranged blowing slots. The acceleration chamber is formed by an outer conical wall provided on a portion of the inside of the outer casing and an inner conical wall provided on a portion of the mixing tube. The tapered walls of the annular acceleration chamber optimize the air jet used for inserting the weft into the shed. The inclination of the taper of the outer wall of the nozzle annular acceleration chamber is 12.degree.-16.degree., and that of the inner wall is 4.degree.-8.degree.. In the preferred embodiment, the taper of the outer wall is 15.degree. and that of the inner wall is 7.degree..
摘要翻译： 用于喷气织机的主喷嘴具有外壳，并且设置有压缩空气导入管道和混合室。 设置有环形分配器环的混合器管被插入外壳中以与分配器环上游的外壳和环形分配室以及在分配器环的下游以及进入混合室的环形加速室形成。 分配器环具有环形布置的吹风槽。 加速室由设置在外壳的内部的一部分上的外锥形壁和设置在混合管的一部分上的内锥形壁形成。 环形加速室的锥形壁优化用于将纬纱插入梭口的空气喷射。 喷嘴环形加速室外壁锥形倾角为12°-16°，内壁锥度为4°-8°。 在优选实施例中，外壁的锥度为15°，内壁的锥度为7°。

摘要： A guide system for a gripper insertion tape in a shuttleless loom which includes a sley with a reed, through the dents of which pass upper and lower warp yarns forming a shed, at least one insertion tape moving with reciprocating motion between the upper and lower warp yarns of the open shed, a gripper fixed to one end of the tape to convey a weft yarn through the shed, and a plurality of guide teeth fixed spaced apart on the sley and projecting through the lower warp yarns of the shed when the shed is open. The teeth are provided with a bearing and guiding surface for the insertion tape and for the gripper. The bearing and guiding surface of the teeth includes a convex surface which extends in the direction of the warp yarns. A control mechanism is also provided making guiding of the insertion tape and the gripper more effective during travel thereof within the shed.

摘要： A reed for an air-jet loom which includes an entry flare allowing several main nozzles to be used. The reed has an inclination of the lower surface of an air guide channel, and an advantageous spacing between the binding spirals which support upper and lower ends of the reeds. The arrangement provides for effective, reliable multi-weft weaving, and can increase the weaving efficiency of the loom, particularly when weaving yarns with irregularities. In a preferred embodiment, the distance between the two binding spirals is approximately 81 mm, with the lower surface of the entry flare having an inclination of approximately 6.degree. with respect to a normal to the rear surface of the channel.
