The filling thread distributor mechanism employs a stationary part having arcuate channels through which filling threads are continuously delivered. In addition, the mechanism has a rotatable part mounted on the weaving rotor which is provided with a plurality of circumferentially disposed transfer channels for sequential alignment with each connecting channel of the stationary part. Each transfer channel also communicates with a picking tube through which filling thread can be picked into a picking channels on the weaving rotor. A cutting mechanism is disposed between a picking tube and a picking channel in order to sever the filling thread and form a new tip for subsequent delivery to the next picking tube of the rotating part.

A weaving rotor of a series shed weaving machine includes a rotating shaft having an axial direction. A plurality of beat-up lamella are arranged on a surface of the weaving rotor, and travel in a direction of rotation of the shaft. The beat-up lamella which are arranged on the weaving rotor to follow one another in the direction of rotation are further arranged so as to be displaced out of alignment in the axial direction of the shaft. The displacement of the beat-up lamella causes weft threads to be beat up uniformly distributed over the width of the cloth to be made so that the cloth is uniform.

A weaving rotor of a series shed weaving machine provides a cover which forms a ring channel with the weaving rotor from a laying-in station up to the cloth edge in the direction of rotation. The ring channel is closed off by further covers, in the direction of rotation and at the side face where the weft arrives. Suction nozzles are mounted along the cloth edge which are dimensioned in such a manner that in spite of the air entering from the insertion and relay nozzles they produce a depression and a flow from the laying-in station to the cloth edge which prevents the deposition of fly. An additional suction nozzle at the arrival of the weft, which is placed in the direction of the weft insertion, additionally stabilizes the flow conditions in the ring channel.

A warp guiding device which includes a holding device for mounting a number of warp guide bars (23) and driving devices (24) for moving the warp guide bars is integrally constructed so that it can be brought into and out of operational connection with a weaving rotor of a series-shed weaving machine. The weaving machine includes an installation arrangement for receiving and securing the warp guiding device on the weaving machine.

The traversing shed loom has a shedding weaving rotor into which weft yarns are picked. The rotor has shedding elements and beating-up combs in which warp placing guides place warn yarns by moving transversely to the direction of rotor rotation. Most of the warp yarns are deflected transversely to the direction of rotation during shedding and the deflection is cancelled only by the shedding elements moving away before the beating-up of the weft so that the warp yarns are realigned. The beating-up combs have at least two warp yarns per occupied space. The position of guides, the geometry and position of the combs, the position of top shed guides and bottom shed guides and the warp yarn placing program are so adapted to one another that the streakiness, i.e., warp streakiness, is controllable.
摘要:
In a weaving rotor of a multiple longitudinal traversing shed weaving machine a beat-up lamella of a first beating-up comb lies in a plane extending substantially perpendicular to the rotational axis of the rotor and centrally between two beat-up lamellae of a next following beating-up comb. The greater division or pitch of these beat-up lamellae permits a faultless insertion of the weft threads into the lanes or intermediate spaces of the shed-forming combs. Nevertheless, when considered with regard to two subsequent beat-up operations, each weft thread is practically beat-up as if each beating-up comb were equipped with the full number of lamellae.

An apparatus for guiding a weft or filling thread in the shed of a weaving machine, 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.

The weft severing device is used for superposed shed type weaving machines and has at least one shear which has a blowing tube. The tube is supplied with blowing air to convey the weft thread. To sever the weft thread, the blowing tube is moved into the cutting element after the weaving rotor has drawn the weft thread over the mouth of the blowing tube.
摘要:
At the weaving rotor there are alternatingly arranged with respect to the direction of rotation thereof first lamellae combs formed by beat-up lamellae for the weft threads and second lamellae combs formed by guide lamellae for the warp threads and including shed-retaining elements for the upper shed position of the wrap threads. The shed-retaining elements for the lower shed position are arranged within each pair of lamellae combs formed by a first lamellae comb and a second lamellae comb at the intersection point of the two groups of warp threads which assume the upper and the lower shed positions, respectively, and are formed by an element extending essentially parallel to the lamellae combs. In the lower shed the warp threads are thus always located in a common plane and the elements forming the shed-retaining elements for the lower shed position can be installed and disassembled without interference with the lamellae combs.
摘要:
A weaving rotor carries lamellae combs, the lamellae of which are provided with shed-retaining elements. Shedding rods which are stroke-wise displaceable in the warp direction are positioned forwardly of the weaving rotor to allocate each warp thread to a shed-retaining element determining either an upper shed or a lower shed. The shedding rods are formed by first racks, the tooth spaces or gaps of which serve as guide means for the warp threads. Thus, there is ensured as precisely as possible pitch or division of the guide means for the warp threads as well as an accurate reproducibility for the shedding rods. The lamellae are positioned on the weaving rotor by second racks having the desired pitch. The first and second racks correspond to each other and are identically designed. Consequently, there results the highest conformity between the lamellae pitch and the pitch of the warp threads, and thus, an optimally ordered run or course of the warp threads from the shedding rods to the weaving rotor. Additionally, manufacture and operation of the multiple longitudinal traversing shed weaving loom are rendered more economical.
