A weaving rotor for a series shed weaving machine has shed holder elements arranged on the surface of the weaving rotor, with at least some of the shed holder elements arranged following one another in the circumferential direction of the weaving rotor being displaced in the axial direction with respect to the weaving rotor.

A series-shed weaving machine which has a machine frame. A warp beam and a weaving rotor are mounted on the frame and a reference plane extends between the axes of the warp beam and the rotor. A warp module is defined by a first subassembly, which includes an arrangement for warp run components of the machine, and a second subassembly, which includes an arrangement for cloth run components of the machine. It is mountable on the frame in first and second orientations in which one of the arrangements is on one side of the reference plane and the other one of the arrangements is on the other side of the reference plane and vice versa, respectively. Depending on whether the arrangement for the warp run is above or below the reference plane, the warp beam rotates in the clockwise or the counterclockwise direction, respectively.

A series-shed weaving machine which has a machine frame. A warp beam and a weaving rotor are mounted on the frame and a reference plane extends between the axes of the warp beam and the rotor. A warp module is defined by a first subassembly, which includes an arrangement for warp run components of the machine, and a second subassembly, which includes an arrangement for cloth run components of the machine. It is mountable on the frame in first and second orientations in which one of the arrangements is on one side of the reference plane and the other one of the arrangements is on the other side of the reference plane and vice versa, respectively. Thus, the warp module can be installed on the weaving machine irrespective of how the warp beam and the cloth beam are arranged by laterally reversing the orientation of the warp module.

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.

A series-shed loom for weaving a fabric from warp threads and weft threads. The loom has a rotor with reeds that comb through the warp threads and carries guide elements which define high points and low points. A multiplicity of elongated laying elements oriented parallel to the axis of rotation of the rotor guide the warp threads towards the rotor and insert them in the high and low points of the guide elements thereon. The laying elements are spaced from the rotor surface, they have a width in the direction of rotation, and warp threads which are adjacent in the fabric are guided over laying elements which are separated from each other by a pitch of at least twice the pitch between adjacent laying elements so that a point of intersection between the warp threads which are adjacent in the fabric is moved relatively further away from the laying elements and so that the point of intersection is further moved closer towards the rotor.

Series shed loom

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.

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.

The weaving rotor for a series shed weaving machine is formed with picking combs which have lamellae of unitary structure to define a weft-guiding part and a warp-guiding part. The lamellae may be made of ceramic pressings with the two projections on the warp-guiding part being spaced apart to provide a relatively large entry zone for the insertion of the warp yarn.

Lamella for a picking comb of a weaving rotor

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.

Weaving rotor for multiple longitudinal traversing shed weaving machines

The weaving machine has a weaving rotor with beating-up lamellae each of which has a beating-up edge perpendicular to the beating-up line during beating-up of the weft yarn. In addition, a rotatable shell is provided to operate after each beating up of a weft yarn in order to draw the cloth in the take-off direction at at least the peripheral velocity of the beating-up lamellae until these lamellae pass out of engagement with the cloth. The shell can be oscillated in synchronism with the beating-up operation via a cam disc coaxial with the rotor and a linkage secured to and end of the rotatable shell 9. The arrangement prevents the cloth from being displaced from the cloth plane by the beating-up lamellae.

Weaving machine

The weft-preparation device for superposed shed type weaving machines comprises a weft measuring drums, a weft-severing device with a plurality of shears and a weft insertion device. Each shear comprises a blowing tube which conveys a weft yarn. The insertion or picking device has a guide duct for the weft which is open on one side and which is closable by a closure member. The severing device places before the guide duct entry whichever shear is guiding a weft for severance. The duct is then closed. When a weft has been fully picked in a picking comb, it is severed. The weft then remaining is conveyed by the blowing tube by way of the picking device into the next picking comb which has meanwhile entered. The severing device is then lowered one step at a time and the subsequent wefts are severed and picked.
