摘要： A running out weft thread end is transferred from a now empty bobbin to a full bobbin during the insertion of a weft thread into the shed of an air nozzle weaving loom from several thread supply bobbins is controlled to obtain a uniform weave even when the thread supply changes from an empty bobbin to a full bobbin. The transfer of the thread is detected and the respective signal is used to temporarily interpose on in a normal thread travelling pattern, a transitional travelling pattern to eliminate disadvantageous influences that affect the weft thread insertion during the transfer of the weft thread from one thread supply to the next. The transitional travelling pattern begins during or immediately after the detection of a thread transfer taking place. The transitional travelling pattern is maintained for a time sufficient to pull a starting amount of weft thread off from the thread supply or until the thread transit time has reached a rated value. Thereafter, the normal travelling pattern controlled by the weft thread insertion program is resumed.

摘要： A nozzle control device for an air weaving loom has a weft thread insertion by one or more main nozzles and a feed advance of the yarn in the air insertion channel by relay nozzles arranged one behind the other at the weaving reed. The relay nozzles are controlled in groups and in sequence in an impulse type manner in such a way that the thread tip zone is seized by the air stream and the thread is pulled through the air insertion channel. The control of the relay nozzles of an air weaving machine is accomplished in such a way that in sequential work steps substantially different types of yarns can be woven with a high quality. For this purpose the durations of air impulses supplied to the relay nozzles arranged in groups, are controlled as a function of yarn specific values modified by a currently measured air effectiveness of the respective yarn being processed.

摘要： The filaments in a weft thread or yarn in a pneumatic loom are tangled and consolidated to prevent untangling of the weft thread when it is transported, after the tangling, through the weft insertion channel in a loom shed. For this purpose the leading end of the weft thread is temporarily stopped in a weft insertion nozzle pipe by a first air stream the so-called holding air stream (19) with a first pressure (P1) between two weaving cycles following each other for holding the weft thread stretched. At the same time a second air stream (20) having a higher pressure (P2) than the first pressure (P1) and a different flow direction than the first air stream (19) is applied to or along a leading end portion of the weft thread for tangling the filaments and thereby locking or consolidating the filaments in the weft thread. Each weft insertion nozzle pipe has a first port and a second port through which the first and second air streams are introduced into the weft insertion the nozzle pipe. The second port is positioned downstream of the first port and closer to a free exit end (15) of the respective weft insertion nozzle pipe but still spaced from the free exit end.

摘要： An arrangement for supplying air with a controlled pressure to the main weft insertion nozzles of an air jet loom includes a single servovalve connected between a pressurized air source, an air vent, and a pressure manifold, and individual shut-off valves respectively interposed in branch lines connected from the pressure manifold to the individual nozzles. A pressure sensor measures the actual pressure provided to the manifold. An electronic controller receives a pressure control signal and controls the servovalve responsive to any difference between the pressure control signal and the actual measured pressure signal. The arrangement is simple, economical, and rapidly reacting, to avoid the need of individual throttle valves or pressure regulators for the individual nozzles.

摘要： A weft thread pre-winder or pre-spooling device for an air jet loom includes a thread storage drum (6) made up of several drum segments (7) that are each adjustable in the radial direction so as to adjust the diameter and circumference of the thread storage drum. Thereby the amount of stored thread can be adjusted. Open gaps or interspaces (8) are formed between respective adjacent drum segments (7), and become larger or smaller depending on the radial adjustment of the segments. Especially for threads that form only a small thread balloon while being drawn-off from the thread storage drum, the threads would tend to get into these interspaces and become caught on the edges or corners of the drum segments, which would lead to energy losses in the thread and interfere with the proper weft insertion and thread transport. To prevent these problems, a protective disk (10) is fixedly or rotatably arranged on or near the endface of the drum (6) on the drawing-off side thereof, and the weft thread (2) is drawn over the outer circumferential edge of the disk (10), which thus prevents the threads from getting into the interspaces (8). The diameter of the disk (10) is substantially matched to the adjusted diameter of the drum segments (7).
摘要翻译：用于喷气织机的纬纱预卷绕机或预缠绕装置包括由多个鼓段（7）组成的螺纹存储滚筒（6），每个滚筒段可径向调节，以便调整直径和周长螺纹存储鼓。从而可以调节存储线程的数量。在各个相邻的鼓段（7）之间形成开口的间隙或间隙（8），并且根据段的径向调节变得更大或更小。特别是对于在从螺纹存储鼓中拉出时仅形成小螺纹球的螺纹，螺纹将倾向于进入这些间隙并被卡在滚筒段的边缘或角部，这将导致能量损失螺纹和干扰正确的纬纱插入和螺纹传送。为了防止这些问题，保护盘10被固定地或可旋转地设置在滚筒（6）的吸出侧的端面上或附近，并且纬纱（2）被拉伸到磁盘（10），从而防止螺纹进入间隙（8）。盘（10）的直径基本上与鼓段（7）的调整直径相匹配。

摘要： Different groups of warp threads are subject to different variations of warp thread tension during shed changes, especially when weaving a fabric having portions such as fabric edges with different weave binding patterns. To provide different warp thread tension compensation for the different thread groups, a cam-like first tensioning module is arranged protruding from the circumferential surface of the backrest along the entire operating width thereof. Second and third tensioning modules are arranged and engaged over the first tensioning module at particular selected axial locations on the backrest. While the second and third tensioning modules provide a constant deflection path distance for second and third warp thread groups guided thereover, the first tensioning module provides a varying deflection path distance for the first warp thread group guided thereover, depending on the oscillating rotational angular position of the backrest. The backrest oscillatingly rotates under a passive compensating spring tension and/or under a positive actuation mechanism coupled to the main loom shaft. The respective warp thread tension of each group of warp threads can be compensated differently or independently from the other groups. The arrangement can be easily reconfigured in a modular fashion to be adapted to the needs of weaving different product articles.

摘要： A method and apparatus remove a faulty weft thread from a beat-up edge or cloth fell by pulling its leading end with a pneumatic thread removal device, which adaptably takes into account the thread characteristics and particularly the twist of the thread. The method maintains the twist of the thread by generating a simultaneously sucking and rotating airflow in the thread removal device, wherein the direction of rotation of the flow is controlled to coincide with the direction of the twist of the weft thread. The pneumatic thread removal device includes an injector nozzle with at least two gas flow inlet ports oriented to respectively cause oppositely rotating suction flows through the nozzle, and a controllable throttle valve to selectively direct a gas flow to the inlet ports.

摘要： A weft thread monitor for an air weaving loom with air jets for inserting weft thread yarns of different qualities such as coarse, fine, thick or thin yarns into the loom shed, has an amplifier or comparator controlled in response to control signals which represent the different yarn qualities for providing a loom control signal which is substantially independent of these yarn qualities. The different quality yarns are pulled off from thread storage spools. The air jets of the main nozzles and of relay nozzles are controlled by an air jet insertion control forming part of a central processing unit. The weft thread monitor with its monitoring or sensor element or elements is arranged at the exit side of the air channel formed by profiled reed teeth of the air jet loom. The output of the sensor element is connected to the input of the amplifier or comparator. A uniform output signal from the amplifier or comparator is assured for all types of weft threads regardless of the yarn specific quality, by controlling the amplifier gain or the comparator threshold, for compensation in response to these yarn qualities. Thus, a very thin smooth yarn or a very thick, corase yarn will yield the same resulting output signal.
