摘要： A weft treatment system and method for removing a mispicked weft yarn from a weft path of a fluid jet loom of the type wherein a weft yarn from a weft supply member is introduced through a weft storage unit to a weft inserting nozzle to be picked. With this system and method, a mispicked weft yarn is detected when mispick occurs. Then, the operation of a cutter and weaving operation of the loom are stopped. Subsequently, the loom is reversely run to expose the mispicked weft yarn at the cloth fell of a woven fabric. More specifically, the weft winding arm is reversely rotated around the storage drum to unwind the weft yarn on the drum. The thus exposed mispicked weft yarn is drawn through the weft storage unit by a weft traction device disposed between the weft supply member and the weft storage unit.

摘要： An air guide member has therein an air guide opening and a slit through which the weft thread passes out of the opening. The opening has an inwardly projected land portion with first and second peripheral sides and includes an air induction section directly connected to the slit and a weft guiding section connected through the air induction section to the slit. The first peripheral side bounds partially the air induction section, while, the second peripheral side bounds partially the weft guiding section. An auxiliary nozzle is associated with one of the air guide members and has an air jet opening exposed to the air induction section so that the air jet from the opening advances toward the weft guiding section after passing through the air induction section. The opening is inclined toward the weft picking direction by a given angle with respect to the direction. An imaginary plane containing the second peripheral side of the land portion intersects the perimeter of the weft guiding section at a position away from the slit.

摘要： A weft picking device of an air jet loom, comprises a plurality of air guide members spaced one from the other and in alignment with the direction of weft insertion. Each air guide member is formed with an air guide opening which forms part of a weft guide channel. Additionally, a plurality of auxiliary nozzles are disposed at certain intervals along the weft guide channel. Each auxiliary nozzle is in the shape of a hollow rod and formed at the wall thereof with an air ejection opening. The outer diameter of each auxiliary nozzle is smaller than the thickness of the air guide member. At least an upper part, having the air ejection opening, of the auxiliary nozzle is located between two opposing planes defining the thickness of the air guide member, thereby preventing the warp yarns from rubbing contact with the auxiliary nozzles.

摘要： A method of removing a mispicked weft yarn when a mispick occurs in a loom. The operation of the loom in a state where the mispicked weft yarn is connected to weft inserting means after the mispicked weft yarn is beaten up by a reed. The mispicked weft yarn is exposed at the cloth fell of a woven cloth. A weft yarn connected to the mispicked weft yarn is inserted from a weft picking side to a counter-weft picking side of the loom. The inserted weft yarn is drawn together with the mispicked weft yarn to the counter-weft picking side, thereby effectively peeling off the mispicked weft yarn from the cloth fell.

摘要： Catch yarns are drawn between a pair of rotatable members which are mounted to be movable toward and away from another and yieldably urged to come together. Detecting means detects the relative movement between the pair of rotatable members and produce an alarm-signal when the relative movement of one rotatable member away from another reaches a predetermined increased value.The catch yarns in tensioned state are further utilized to hold the detecting means at a rest position thereof. The detecting means also produces an alarm-signal upon the breakage of the catch yarns.

摘要： A weft picking system for an air jet loom provided with a microcomputer as a controller. The weft picking system comprises a weft traction device including a pair of rollers one of which is driven by an inverter motor. A weft yarn fed from a weft measuring and storing device can be put between the rollers to be drawn toward a weft posture regulating nozzle. The weft posture regulating nozzle is arranged to project the weft yarn into the shed of warp yarns while regulating the posture of the weft yarn, under the influence of an air jet ejected therefrom and under assistance of air ejection from a plurality of sub-nozzles. The rollers are always driven to rotate during a weaving operation of the loom. A change-over device is provided to change the weft yarn from a first state of being put between the rollers to a second state of separating from the rollers or vice versa. The changing from the second state to the first state of the weft yarn is made after the starting of ejection of the fluid jet from the weft posture regulating nozzle in a weft picking cycle thereby preventing the weft yarn from being slackened in a location between the weft traction device and the weft posture regulating nozzle.
摘要翻译：一种用于喷气织机的纬纱拾取系统，其具有作为控制器的微型计算机。纬纱拾取系统包括一个纬纱牵引装置，该牵引装置包括一对辊，其中一个由逆变电动机驱动。从纬纱测量和存储装置输送的纬纱可以放置在辊之间，以向纬纱姿势调节喷嘴拉出。纬纱姿势调节喷嘴布置成在经过喷射的空气喷射的影响下并且在从多个副喷嘴的空气喷射的辅助下，将纬纱投射到经纱的梭口中，同时调节纬纱的姿势。在织机的织造操作期间，辊总是被驱动旋转。提供转换装置以将纬纱从放置在辊之间的第一状态改变到与辊分离的第二状态，反之亦然。在纬纱采摘周期开始从纬纱姿势调节喷嘴喷射流体射流之后，进行纬纱从第二状态向第一状态的变化，由此防止纬纱在纬纱之间的位置松弛牵引装置和纬纱姿势调节喷嘴。
