    • A fluid jet loom includes a source of pressurized fluid, a magnetic valve, and at least one nozzle, such as a weft insertion air jet nozzle, as well as at least one flexible pressure hose connecting and providing pressurized fluid from the magnetic valve to the nozzle. In order to detect any hole, rupture or separation of the pressure hose, the hose includes at least one electrical conductor embedded in or arranged on the hose wall. An electrical current flows through the electrical conductor, which preferably forms a conductor loop and especially a resonant circuit loop. By monitoring an electrical characteristic, such as the resonant frequency, of the electrical signal received from the conductor loop, any disruption in the pressure hose can be immediately detected as a change in the monitored electrical characteristic, which in turn causes a loom stop signal to be generated.
    • 流体喷射织机包括加压流体源,电磁阀和至少一个喷嘴,例如引纬空气喷嘴,以及至少一个柔性压力软管,其连接并将加压流体从电磁阀提供给 喷嘴。 为了检测压力软管的任何孔,破裂或分离,软管包括嵌入或布置在软管壁上的至少一个电导体。 电流流过电导体,其优选地形成导体环路,特别是谐振电路回路。 通过监测从导体回路接收的电信号的电特性(例如谐振频率),可以立即检测压力软管中的任何中断,作为监测的电特性的变化,这又导致织机停止信号 生成。

    • The starting time of a weft thread insertion in a jet loom is automatically adapted to a change in the speed of the main loom drive shaft, in order to assure that the leading end of the weft thread always arrives at the same time at a weft stop motion device at an exit end of a weft insertion channel through the loom shed. For this purpose, the starting time of the weft insertion is advanced when the loom drive shaft rpm is increased and delayed when the rpm is decreased. The advance or delay has reference to a weaving cycle that begins with the opening of a shed and ends when the shed is fully closed. The flight time .DELTA.t.sub.F of a weft thread through the shed is constant. The adaptation is performed in response to measuring the rotational drive shaft angle .alpha..sub.AR at which a weft thread arrives at the weft stop motion device and determining the starting time in such a way that the weft arrival time (t.sub.2, t.sub.4, t.sub.6) always takes place at substantially the same rotational drive shaft angle .alpha..sub.AR.
    • 纬纱插入喷气织机的开始时间自动适应于主织机驱动轴的速度变化,以确保纬纱的前端在纬纱停止时始终到达同一时间 运动装置在纬纱插入通道的出口端通过织布机棚。 为此,当转速降低时织机驱动轴转速增加并延迟时,引纬的开始时间将提前。 提前或延迟参考了从开口开始的织造周期,并且当棚子完全关闭时结束。 通过梭口的纬纱的飞行时间DELTA tF是常数。 响应于测量纬纱到达纬纱停止运动装置的旋转驱动轴角度αAR而执行适应,并且确定起始时间,使得纬纱到达时间(t2,t4,t6)总是采用 位于基本相同的旋转驱动轴角度αAR。

    • In a loom of which the backrest (3) and/or the warp stop motion (17) are adjustably supported on the machine frame (22) and are adjustable by associated adjusting equipment with at least one adjusting function, at least the backrest (3) and/or the warp stop motion (17) are automatically adjusted. To achieve this, at least one controllable driven adjusting device (30) connected to the loom control is allocated to the adjusting equipment. The existing actual position of the backrest and/or of the warp stop motion is determined. At least the measured values characteristic of the actual position are compared to prescribed nominal or desired values. From this comparison, an adjusting signal is generated, which is then provided to the adjusting device, which then automatically moves the backrest (3) and/or the warp stop motion (17) automatically into the respective desired position.
