  • a circular loom of the type mentioned is from the publication EP 0080453 A2 known.
  • the gates are driven by a motorized rotor with carrier rollers.
  • Concentric around the races are Arranged warp spool devices, each of which feeds a warp thread over several thread deflections from a warp thread spool (warp spool) via a tensioning device and a compartment guide between the upper and lower raceway through the weaving core.
  • the shuttles pass between the alternately fanned out warp threads, with the shuttle rollers running over the warp threads below.
  • the fabric produced is continuously pulled off the weaving core so that an endless fabric tube is created.
  • the necessary multiple deflections of the warp threads do not permit a high thread tension, with the loading of the warp threads by the shedding also leading to an uneven thread tension in the fabric.
  • the fabric cannot be pressed firmly against the contour of the weaving core, which is entirely practical for the usual continuous drawing off of an endless fabric tube from the stationary weaving core.
  • the known circular looms are unsuitable for weaving a loom core with stationary fabric, in particular for weaving a loom core with a variable core contour.
  • products with a hollow profile such as rims, tubes and shafts with unequal diameters, cannot be produced in their finished geometry with the known circular weaving machines.
  • the warp threads are over tiltable warp thread spools and yarn guide tubes crossing the travel grooves for the circulation of the shuttles.
  • the running grooves are interrupted by slots, along which the thread guide tubes assume their changing position.
  • the invention is based on the object of providing a circular weaving machine and a method for producing a hollow-profile-like fabric, which expands the applicability of the known circular weaving machine and in particular enables greater variability of the fabric structures and patterns that can be produced and contoured weaving of a weaving core with variable geometry .

  • the multi-part, ring-shaped guide rails 23.1, 23.2, 23.3 each form a circular orbit (Guide track) 23 and specify the parallel guide lines of the shooter 5 respectively.
  • the two inner partial rails 24 of the guide rails 23.1, 23.2, 23.3 pointing in the direction of the weaving axis 3 radially delimit a possible usable weaving plane 6.1, 6.2, 6.3, with the shuttles 5 rotating outside of these weaving planes weaving planes 6.1, 6.2, 6.3.
  • the shuttles 5 of the central guide rail 23.2 guide the weft threads 8 for weaving the weaving core 1a between the associated inner part rails 24 in a straight line to the weaving point on the weaving core 1a.
  • the weft threads 8 of the two flanking guide rails 23.1, 23.3 are each guided over a thread deflection in order to then also be guided in a straight line to the weaving point on the weaving core 1a.
  • the thread deflections of the two flanking guide rails 23.1, 23.3 serve to bring the weft threads 8 of the parallel rotating shuttles 5 closer together and thus to combine the three weaving planes 6.1, 6.2, 6.3 determined by the guide tracks 23.1, 23.2, 23.3 and the course of the weft thread.
  • the positioning devices 13 for moving and positioning the warp bobbin devices 10 or the warp bobbins 11 are analogous to the positioning devices 13 of the circular loom 1 , 2a,b,c or after 12 and 13 formed, wherein the warp coil devices 10 and the warp coils 11 on each side of the three combined weaving planes 6.1, 6.2, 6.3. are positionable.
  • the warp threads 12 of the warp spools 11 lead linearly and with a variable weaving angle 16 to the weaving planes 6.1, 6.2, 6.3. to the weaving point on the weaving core 1a, wherein for the alternating spreading of the warp threads 12 each warp bobbin device 10 or each warp thread bobbin 11 by means of the movable bobbin gripper 14a of the positioning device 13 in both directions through the three weaving planes 6.1, 6.2, 6.3. is passed through at the same time.
  • the merger of the web levels 6.1, 6.2, 6.3. reduces the required travel distance for changing the position of the warp bobbin device 10 or the warp thread bobbin 11.
  • a fabric 17 produced is shown as an example with a weaving pattern in which the weaving mode provides for a warp thread change after the passage of three shuttles 5, so that here three weft thread windings are woven simultaneously with a warp thread 12.
  • This weaving mode can be generated in various operating modes of the circular loom, for example in the operating mode in which a passage of one contactor 5 of the three parallel guide rails 23.1, 23.2, 23.3 takes place between the warp thread change.
  • Another mode of operation is possible, in which, between the warp thread change, the passage of a rapidly revolving pair of shuttles 5 on the middle guide rail 23.2 and a relatively slowly revolving shuttle 5 on the adjacent guide rail 23.1 on the left takes place.
  • the relatively slowly revolving shuttle 5 passes through on the guide rail 23.3 adjacent to the right.
  • shuttles 5 can be operated side by side with very different rotational speeds, which is particularly important when processing weft threads 8 made from different woven materials.
  • the shuttles 5 operated in the parallel guide rails 23.1, 23.2, 23.3 can also rotate in the same direction of rotation or also in the opposite direction of rotation, depending on the desired fabric properties.
  • FIG. 15 shows a half-page section of a circular loom, which is similar to the circular loom 12 , 13 is constructed, but provides a different number and arrangement of positioning devices 13.
  • This circular loom has two warp bobbin wreaths 21.1a, 21.1b and 21.2a, 21.2b on both sides of the weaving plane 6 formed by the multi-part guide rail 23 and the course of the weft threads 8.
  • the radially inner warp bobbin ring 21.1a, 21.2a on each side of the weaving plane 6 is rotatably mounted by means of a middle roller bearing relative to the respective radially outer warp bobbin ring 21.1b, 21.2b, while the respective radially outer warp bobbin ring 21.1b, 21.2b by means of the middle roller bearing is rotatably mounted relative to the radially inner warp bobbin ring 21.1a, 21.2a and by means of an outer roller bearing relative to the machine housing 4.
  • Each of the warp bobbin rings 21.1a, 21.1b, 21.2a, 21.2b are driven and controlled separately by a motor 22 in each case.
  • 21.2b positioning device 13 On the warp bobbin rings 21.1a, 21.1b and 21.2a, 21.2b positioning device 13 are arranged circumferentially, which according to the embodiment 12 , 13 are each formed with two axially movable bobbin grippers 14a, 14a.
  • the positioning devices 13 arranged on the cascaded warp bobbin rings 21.1a, 21.1b and 21.2a, 21.2b are thus arranged in two radially staggered circular planes concentrically around the weaving axis 3 and on both sides of the weaving plane 6 and implement both the axial movement and the circumferential movement of the Warp coil devices 10 or warp coils 11 with the advantages described above.
  • the cascaded warp bobbin wreaths 21.1a, 21.1b and 21.2a, 21.2b also enable many warp bobbin devices 10 or warp bobbins 11 to be arranged in a very small space and thus promote a particularly narrow design of the circular loom.
  • In 16 is a circular loom with a rotor ring 2 and two shuttles 5 revolving with the rotor ring 2, similar to the design of the rotor ring 2 Figures 1 to 4 shown.
  • each warp bobbin device 10 or warp bobbin 11 can be autonomous and arbitrary be moved axially, radially and in the circumferential direction to the weaving axis 3 and be positioned at any point on the side of the weaving plane 6.
  • the handling robots 28 allow maximum degrees of freedom for the positioning of the warp bobbins 11 on both sides of the weaving plane 6 and for the travel of the warp bobbins 11 through the weaving plane 6.
  • handling robots 29 are provided, which have gripper elements which automatically pick up the bobbins 7 from the shooters 5 and place them on them when they are at a standstill.
  • this enables the automated exchange of used bobbins 7 and, on the other hand, an automated change of location of lap bobbins 7 in operation with one another, such as e.g. B. the shot coils 7 of the parallel contactors 5 of both rotor rings 2.1, 2.2, as indicated by the arrow in 17 clarified.
  • a special undulation of the weft threads 8 with the warp threads 12 can thus be achieved - in particular during the placement of a warp thread spool 11 in the intermediate position between the two rotor rings 2.1, 2.2 (position M) - with a fabric 17 being produced with further special weaving patterns and fabric properties can.
