摘要： 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.
摘要翻译：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。

摘要： In the event of an interruption of the weaving process and in the case of weaving-technical operations, such as tabby weaving and unraveling, a trailing of warp thread bobbins and thus a trailing of warp threads which are withdrawn from the bobbins and form a warp thread family, cannot be avoided without significant expenditures. The trailing results in a so-called trailing length in the thread family which, unless it is correspondingly taken up and correspondingly released during the new start of the weaving process, results in an overstretching of the warp thread family during a starting operation of the bobbins. This disadvantage is avoided by deflecting the thread family within a feeding stand, in the event of a weaving stop, in a controlled manner from a reference plane into at least one defined position. At the new start of the weaving process, the deflection is eliminated in a controlled manner.
摘要翻译：在织造过程中断的情况下，以及在编织技术操作的情况下，例如平纹织造和开卷，经线的尾部和经线的拖尾从筒管中退出并形成翘曲线程家庭，无法避免大量支出。拖尾导致在线族中所谓的拖尾长度，除非在织造过程的新开始期间相应地被相应地占用并相应地释放，所以在线轴的起动操作期间导致经线系列的过度拉伸。通过在编织停止的情况下以一种受控的方式从参考平面偏转到至少一个限定位置来避免进给架内的螺纹系列偏转的缺点。在编织过程的新开始时，以受控的方式消除偏转。

摘要： A gripper loom is equipped along its reed or slay beam with a plurality of compartments formed by separation walls extending in parallel to each other and in parallel to the lower shed forming warp threads which pass through these compartments. The upper edges of the separation walls are aligned with each other and with a guide surface of the gripper rods so that the upper edges form extension guide surfaces for the gripper rods. Thus, the lower shed forming warp threads do not interfere with the proper motion of the gripper rods.
摘要翻译：夹纱机沿着其簧片或杀手梁配备有多个隔室，隔室由彼此平行延伸并平行于穿过这些隔室的下部梭口成形经线形成的分隔壁形成。分隔壁的上边缘彼此对准并且与夹持杆的引导表面对齐，使得上边缘形成用于夹持杆的延伸引导表面。因此，下部成形的经线不会妨碍夹持杆的适当运动。
