    摘要: A method and arrangement for picking a weft thread by means of a weft thread inserting comb in a jet loom. The comb is composed of a plurality of juxtaposed comb members which are mounted on a reciprocating slay of the jet loom. Each comb member has a pair of shank portions which define a weft inserting opening and an unthreading channel. The comb members, when in their operative positions, define a weft inserting channel. At least one of the comb members has secondary carrying fluid conduit means which directs via an outlet a stream of a secondary carrying fluid into a zone of said weft inserting channel which is disposed below the axis of the channel relative to the unthreading channels of the comb.

    摘要: Weft inserting device adapted to be fixed on the frame of a jet loom or to the beat-up motion thereof. The device has two mixing tubes which are united at the location of their outlet ends so as to form a single central outlet portion terminating in a single outlet opening, the outlet opening being followed by a directing portion with an open passage through. In the weft inserting device of the invention, the central outlet portion of the weft inserting device, starting from the discharge ends of the mixing tubes, is divided by means of a baffle disposed in a first plane which is perpendicular to a second plane containing the longitudinal axes of the mixing tubes, the baffle extending from the discharge point of the mixing tubes throughout at least a portion of the length of the central outlet portion. The longitudinal axis of the baffle lies in a plane which contains the axis of the directing portion of a weft inserting device.

    摘要: A picking channel for pneumatic jet looms with auxiliary blowing sections disposed across the weaving width and consisting of at least three auxiliary blowing nozzles the relative positions of the axes of which being those of skew lines with the axis of the first auxiliary blowing nozzle crossing the axis of the weft thread under insertion. The axes of the other auxiliary blowing nozzles pass said axis of the weft thread under insertion of the outside, in the direction of the axis of the first auxiliary blowing nozzle. The various dispositions of both the auxiliary blowing sections and nozzles insure reliable weft insertion, and economic exploitation of the energy of the carrier medium and, consequently, a greater weaving width.

    摘要: A loom having a means for automatically unweaving the weft upon the occurrence of a weaving fault, thereby reducing the labor needed to overcome such weaving fault and thus increasing the efficiency of the loom. The apparatus includes a device for the selective prevention of the weft from entering the shed of the loom, said device being mounted on the loom between the weft supply and the weft-entering end of the shed. The invention may be applied to looms wherein measured lengths of weft are inserted mechanically into the shed, or to jet looms, wherein measured lengths of weft are inserted by jets of inserting fluid such as air or water into the shed of the loom.

    摘要: A weft guiding comb of a jet loom wherein the weft is inserted across the shed by a stream of fluid carrying medium. The comb contains relay bodies located under the lower warp threads of the shed at the reed. The reed consists of flat dents to beat up the inserted weft to the fabric, the wall of which adjacent to said lower warp threads of the shed is one part of the weft guiding comb wall. Such wall is provided with saw-toothed projections, the face surfaces of which at least in the moment of the weft insertion carry the lower warp threads of the shed, and in the faces of which, transverse to the direction of the weft insertion, there are the mouths of the relay nozzles pointing in the direction of the weft insertion. The other part of the weft guiding comb wall are the backs of the reed dents, said dents being above the wall of the relay body with saw-toothed projections provided with nose extensions, the length of which corresponds with the width of the back surface of the relay body saw-toothed projections.

    摘要: The present invention relates to an apparatus for accurately controlling the distribution of pressure fluid through a number of branch conduits, the apparatus being advantageously employed for jet looms. The apparatus eliminates excessive wear of mutually engaged parts which would otherwise cause unwanted time delays in the operative steps of the system with which it is employed. The apparatus includes a plurality of valves, each valve having a movable valve element coupled with the outer race of an anti-friction bearing mounted on an eccentric by means of a piston and a push rod provided with a spring which maintains the piston in engagement with the outer race. The valve is opened when a stop on the piston is moved by the eccentrics into engagement with the other end of a push rod which forms a part of the movable valve element.

    摘要: A picking comb, particularly for jet looms. The comb has an array of active, monitoring and passive guide teeth each having a picking portion and a mounting portion and fixed by its mounting portion in spaced side-by-side releation on a carrier means. At least one of said guide teeth has its picking portion separate from its mounting portion. The picking portion is provided with a connecting element fitting into a corresponding bore in the mounting portion. Correct positioning of the two portions is assured by interfitting positioning parts and a clamping element. The detachable connection between the picking portion and the mounting portion of a tooth makes it easier to replace a defective picking portion without the necessity of removing the whole picking channel or a section thereof.

    摘要: Let-off motion for elongated material wound on a let-off beam. Such let-off motion comprises a tension detector connected to the input of a let-off element, the output of which is connected with the control element of the driven let-off unit, with the input shaft of the drive and output shaft of the let-off drive, which responds to changes of the control magnitude value in its control element by a change of the relation of angular velocities between the input and output shafts. The input of the let-off element is a rotary disc slidably arranged between two axially arranged clutch discs of the let-off element, the clutch discs being mutually positively rotatable in opposite directions. The clutch discs of the let-off element are drive-coupled with the input shaft of the driven let-off unit, and the disc of the let-off element is provided with a central, internally threaded hole which receives and is threadedly mated with the threads on the spindle of the let-off element. The spindle is mounted slidably but non-rotatably in the body of the let-off element, and creates the output of the let-off motion let-off element.

    摘要: There is disclosed a device for cutting weft in looms with mechanisms for multi-weft weaving. The cutting device includes a holder on which mutually adjustable shields are mounted. The shields are provided with entrapping dents for the introduction and location of weft between the blades of cutting jaws at a cutting point. The cutting device has a movable jaw which is adjustably connected to a control lever. Adjustable shields and cutting jaws permit the use of the entire length of knife blades secured to the jaws. In this manner, during cutting the overlap is minimized and the lifetimes of the cutting edges and the cutting jaws are increased.
