摘要： A weft yarn insertion nozzle device for a jet weaving machine, comprises a supply, an outlet nozzle, a conduit connecting the supply and the outlet nozzle and a valve unit. The valve unit comprises a displaceable, soft-magnetic valve body and a coil for generating a magnetic field extending through the valve body, wherein the valve body is arranged within the conduit such that the flowing of pressurized medium therethrough exerts a force on the valve body which is opposite to the force as generated by the magnetic field.

摘要： A pneumatic weaving machine has an air transport channel for blowing the weft threads, formed by the reed lamellae and open at one side. A plurality of auxiliary blowing nozzles are directed through this open side obliquely inward. The invention provides means whereby the jet direction of the auxiliary nozzles may be influenced such that a larger or smaller component transverse to the weft direction is obtained. Thereby friction forces on the thread may be controlled dependent on the yarn type.

摘要： The present invention relates to a serial shed weaving machine with a weaving rotor. Guide channels for weft threads transported by a flowing fluid are mounted on the weaving rotor. The guide channels are formed from a plurality of elongated, tube-like channel elements having a closable weft thread exit gap. The channel elements have complementary end configurations such that they can be moved together to form a closed guide channel. The channel elements are movable back and forth in the weft insertion direction. When the channels are moved in a first direction, the closed guide channel is opened and gaps are formed between the channel elements and each channel element is moved out of its associated part of the warp shed. When the channel elements are moved in a second direction, each channel element is moved back into its associated part of the warp shed and the guide channel is closed. The total excursion of each channel element in each direction is at least as great as the length of the element. Since the motion of the channel elements is exclusively back and forth in the weft insertion direction, the drive for such motion is relatively simple. Further, since the channel elements are each several centimeters long, the number of possible leak locations is sharply reduced over the prior art such that the weft threads may be inserted by suction air pressure.
摘要翻译：本发明涉及一种具有编织转子的连续梭织机。由流动的流体输送的纬纱的引导通道安装在织造转子上。引导通道由具有可闭合的纬纱出口间隙的多个细长的管状通道元件形成。通道元件具有互补的端部构造，使得它们可以一起移动以形成封闭的引导通道。通道元件可沿纬纱插入方向前后移动。当通道沿第一方向移动时，打开闭合的导向通道，并且在通道元件之间形成间隙，并且每个通道元件移出其相对于经纱梭的部分。当通道元件沿第二方向移动时，每个通道元件被移回到经纱梭的相关联的部分中，并且引导通道关闭。每个通道元件在每个方向上的总偏移至少与元件的长度一样大。由于通道元件的运动在纬纱插入方向上是独一无二的，所以这种运动的驱动相对简单。此外，由于通道元件的长度为几厘米，与现有技术相比，可能的泄漏位置的数量急剧减少，从而可以通过吸入空气压力插入纬纱。

摘要： The loom includes a reed constituted by a plurality of blades which are in alignment and parallel to each other. These blades have respective substantially circular apertures which have the same diameter and are aligned with each other to form a straight passage for guiding the pneumatic insertion of the weft. The portion of each blade between the aperture and the side of the blade facing the fabric (T), in use, has a substantially horizontal slit which extends from the aperture to the side of the blade. Between each pair of adjacent blades are interposed first and second spacer elements which are arranged respectively above and below the aperture and the slit of the blade. The loom includes drive means which, when activated, cause translational movement of the reed perpendicular to the longitudinal axis of the passage formed by the apertures in the blades of the reed.

摘要： A strand is furnished to a strand consuming unit, e.g. loom, having a periodic demand for a finite length of strand by:(a) continuously advancing the strand from a supply source for winding onto a first surface,(b) continuously advancing the strand from the first surface onto one end of a second surface for rewinding thereof on the second surface,(c) periodically operating the consuming unit to withdraw the strand from an opposite end of such second surface while continuing the advance of the strand both to such first surface and from the first surface toward the first end of the second surface, and(d) halting withdrawal of the strand when a finite length thereof has been withdrawn from the opposite end of the second surface by the consuming unit.Upon the withdrawal of the finite strand length from the second surface, the strand is mechanically engaged proximate the beginning of the second surface so as to preclude additional strand from being accidentally advanced from the first surface by the tension in the withdrawing strand.The invention also contemplates the adjustment of the conditions of the projection of the strand by the insertion nozzle for the purpose of adjusting the effective thrust applied by the nozzle to the strand so that the leading end of the pulse of air emitted by the injection nozzle always precedes the leading end of the strand being projected therefrom and bunching up of the leading strand end is thereby avoided. Ideally, the thrust applied by the nozzle to the strand and the resistance of the strand to advance are correlated so that the leading end of the strand at least substantially, and preferably precisely, coincides with the withdrawal of the final portion of the finite strand length from the second surface and thus the strand extends in a straightened out condition from the beginning of such surface through the entire shed of the loom.INDEXCross Reference to Related ApplicationsField of InventionBackground and Prior PracticeSummary of the InventionStatement of ObjectsBrief Description of DrawingsGeneral Description of System of InventionDetailed Description of InventionI.

摘要： An apparatus for guiding a weft or filling thread in the shed of a loom, the weft thread being driven by a flowing fluid medium, comprises two lamellae combs which can dip into and out of the warp threads. The lamellae or equivalent plate-like guide elements of the lamellae combs each possess a throughpass opening for guiding the weft thread and a thread exit or outlet opening. When the lamellae are in a position completely immersed in the shed they are interleaved or shoved into one another and form a guide channel for the weft threads, this guide channel being coherent or continuous in the weft insertion direction. Hence, the thread exit or outlet openings are sealed, so that the guide channel also is continuously closed in radial direction. The closed guide channel renders possible, on the one hand, a controlled flight of the weft thread, a reduced energy consumption and driving of the weft thread both by a blowing action and also by a suction action and, on the other hand, can be particularly advantageously employed at a multiple longitudinal traversing shed loom containing a weaving rotor.
摘要翻译：一种用于在织机的梭口中引导纬纱或填充线的装置，纬纱由流动的流体介质驱动，包括可以浸入和流出经线的两个薄片梳。薄片梳状体的片状或等效的板状导向元件各自具有用于引导纬纱和螺纹出口或出口的通道开口。当薄片处于完全浸没在梭口中的位置时，它们彼此交错或推入并形成用于纬纱的引导通道，该引导通道在引纬方向上相干或连续。因此，螺纹出口或出口被密封，使得引导通道也在径向方向上连续关闭。封闭的引导通道一方面使得纬纱的受控飞行成为可能，通过吹动动作以及通过抽吸动作减少能量消耗和纬纱的驱动，另一方面可以是特别有利地用于包含织造转子的多纵向横向梭织机。
