Definitions

  • the invention relates to a take-off device for the fabric web on a textile, preferably weaving machine, with a driven fabric take-off roller and a rod-shaped deflecting element for the fabric upstream or downstream thereof, the deflecting elements abutting the fabric take-up roller with the interposition of the fabric and - at least during operation - are arranged in a fixed position.
  • a take-off device for the fabric web on a textile, preferably weaving machine, with a driven fabric take-off roller and a rod-shaped deflecting element for the fabric upstream or downstream thereof, the deflecting elements abutting the fabric take-up roller with the interposition of the fabric and - at least during operation - are arranged in a fixed position.
  • a take-off device is particularly intended for weaving machines with extremely high fabric take-off tension and high performance, i.e. large weaving width and high speed.
  • the upstream of the fabric take-off roller designed as a roller deflection element, has a smooth surface and is carried along by the material running over it and onto the fabric take-off roller or set in rotation. The following phenomenon can be observed in practice.
  • the fabric in the area between the sheet stop or spreader on the one hand and the fabric take-off roller on the other hand can experience a strong jump. This is due to the fact that the fabric initially runs freely after leaving the spreader and is pulled together relatively strongly by the weft thread tension in the weft direction. However, the warp thread tension is stronger than the weft thread tension.
  • the fabric is striving for a state in which the wrap angle of the weft threads around the warp threads is greater than that of the warp threads around the weft threads.
  • the fabric web now runs into the take-off device, which works with particularly high contact pressures on the circumference of the fabric take-off roller. It should be made possible that the take-off rollers do not have a particularly rough surface, e.g. Corundum, and also need not have driver pins, because these devices have a harmful effect on sensitive tissues.
  • the take-off rollers do not have a particularly rough surface, e.g. Corundum, and also need not have driver pins, because these devices have a harmful effect on sensitive tissues.
  • the removed fabric can receive permanent creases when it runs off the take-off roller. This is where the invention comes in, the aim of which is to take measures which can prevent these undesirable creases in the fabric.
  • the invention has for its object to provide a haul-off device which is particularly improved in this regard, in particular to achieve high slip resistance on the haul-off roller and avoid wrinkles in the haul-off of the fabric.
  • the invention consists in that the material take-off roller is arranged to be movable transversely to its axial direction and the clear distance between the deflecting elements is smaller than the diameter of the material take-off roller and that the deflecting element upstream of the material take-off roller is designed as a rod secured against rotation, the two halves of which are opposed - in Seen the direction of the fabric - has diverging thread grooves.
  • the fabric 1 (weaving width B) is fed according to arrow 51 via a fabric support 52 to a deflecting rod 3.
  • a fabric support 52 In its sections (38, 39) opposite thread grooves 41, 42 (see FIG. 3) that diverge in the direction of travel 51 of the fabric web 1.
  • the fabric 1 then passes through a take-off roller 5 provided with a rubber pad 4 and then via a deflecting roller 3c arranged downstream thereof to a fabric tree 65 on which the fabric 1 is wound.
  • Roller 5 has a diameter D which is greater than the clear distance A between the parts 3, 3c.
  • the goods take-off roller 5 is driven via gear wheels 18, 19, 20, which are mounted in one cheek 23 of the machine frame 2.
  • the drive is guided from the gear wheel 20 to the roller 5 via a cardan or ball joint 21.
  • Roller 5 is thus set in constant rotation during operation (positive goods deduction).
  • the entire fabric removal device is designated by 15 in FIG. 1.
  • the rod 3 upstream of the main take-off roller 5 has a groove 53 into which a carrier 47 engages, which is connected to a rod 55.
  • This is rotatably mounted in a trough 56 of a holder 6 of the machine frame 2.
  • the deflecting rod 3 can be pivoted according to arrow 46 into the position 3b shown in dash-dot lines when the fabric 1 is tensionless or removed.
  • the carrier 47 is constantly pressed against a stop 48 of the holder 6. This is achieved in that the fulcrum 57 of the rod 55 is selected such that the force R resulting from the fabric 1 and the tensile force component P resulting from the fabric 1 during operation runs below the fulcrum 57 in FIG. 1 . This creates a counterclockwise torque about pivot 57 during operation.
  • the roller 3c connected downstream of the take-off roller 5 is rotatably mounted in a trough 22 of the frame 6.
  • the deflecting rod 3 is designed as in FIG. H. secured against rotation. At the ends it carries inclined needle rollers 61a, which - while keeping their inclined position in space - are rotatably mounted.
  • the effective length of the deflection rod 3 is adapted to the width B of the fabric 1.
  • the rollers 61a together with the thread grooves 41, 42 cause the fabric 1 to spread.
  • the parts 3, 3c are stored in a stationary manner at least during operation. Roller 5 is pressed under the fabric pull Z against the parts 3, 3c, whereby slipping back of the fabric 1 can be avoided.
  • the downstream deflection roller 3c can also be driven by a separate drive, cf. Arrow 58. Their peripheral speed can be higher than that of the take-off roller 5.
