Definitions

  • the invention relates to a holding device for the rails, in particular contact rails of the warp guard of a weaving machine, with a plate-shaped part encompassing the rails, which is arranged displaceably on a fixed support.
  • the plate-shaped part on the carrier is adjustable and lockable by means of an elongated hole and associated clamping screw. If the weaving machine has a large weaving width, several such carriers with displaceable, plate-shaped parts are needed in order to hold the rails of the warp thread monitor which extend over the entire weaving width. With the known adjusting device, it is difficult to bring about the same height position in the individual holders and plate-shaped parts, so that the rails of the warp thread monitor have exactly the same position over the entire weaving width and generally run horizontally. The drop height of the associated parking slats depends on the position of the contact rails of the warp thread monitor.
  • the invention consists in that a movable molded body is connected into the gear connection between the plate-shaped part and the carrier, by means of which the plate-shaped part can be moved relative to the carrier.
  • the weaving machine frame contains an oval cross-section rod 1 running in the weft direction, on which several, U-shaped holder 2 are fastened by means of screws 3 and clamping wedge 4. 1 and 2, a support 5 is inserted into each frame 2 from above. In its lower part it contains a sloping bar 5a, while in the upper part it consists of two parallel walls 5b.
  • a plate-shaped part 6, which has feet 7, is pushed between the walls 5b.
  • the lower end of the feet 7 in FIG. 1 lies on a straight line 10, which is indicated by dashed lines in FIG. 1.
  • the strip 5a has a toothing 8 in which teeth 9 engage, which are attached to the lower end of a sliding wedge 11.
  • the upper end 12 of the sliding wedge 11 forms a guide for the feet 7 arranged on the straight line.
  • the sliding wedge 11 has a nose 12 which projects between the two walls 5b.
  • the sliding wedge 11 is connected as a molded body in the gear connection (operative connection) between the carrier 5 and the plate-shaped part 6.
  • the wedge 11 When the wedge 11 is moved to the right in FIG. 1, it is expediently lifted out of the toothing 8 by inserting a tool into a bore 15 and pushed to the right according to arrow 16. He moves under the feet 7, so that the plate 6 is raised.
  • in-slots 17 are guided as a whole with 18 designated contact rails, while guide rails 19 are held in slots 21 of the carrier 5.
  • the contact rails 18 serve to switch off the weaving machine when one of the parking slats 22 falls due to the breakage of a warp thread 23.
  • the guide rails 19 serve to keep the slats 22 lined up on the contact rail 18 at a distance from one another by the slat feet 24 between two guide rails 19 are held.
  • the shed 51 A corresponding distance between the warp threads 23 above the rod 1 is denoted by A.
  • the wedge 11 After moving the wedge 11 in the frame of the opening 26 made in the carrier 5, the wedge 11 reaches e.g. in the position 11a of Fig. 3, in which the plate 6 is positioned in the higher position 6a. This corresponds to the larger distance B of the warp threads 23 assumed in FIG. 3 with a larger shed 52.
  • the contact rails are in position 18a.
  • the fall time of a slat 22 in the event of a warp thread break is the same as in the position according to FIG. 1, since in both positions the fall height of the slats 22 has the same distance C between the contact rail 18 and the upper end of the associated slot of the slats 22.
  • the carrier 5 and the plate 6 are made of plastic, e.g. made of nylon or teflon (tetrafluoroethylene). Both the carrier 5 and the plate 6 are held at 31 in a guide of the frame 2. The weight of the rails 18, 19 pushes the parts down in the drawing, so that the teeth 9 are also constantly held in the toothing 8 and the wedge 11 cannot slide off to the left.
  • the toothing 8 enables the wedge 11 to be gradually adjusted for each carrier 5 of the warp thread monitor. If necessary, brands, e.g. Numbers are attached to the individual gaps in the toothing 8, so that the same position can easily be achieved for each frame 5 or wedge 11 over the entire weaving width of the weaving machine, the contact rails 18 being at exactly the same height and running horizontally.
  • the arrangement is such that both the wedge 11 on the bevel 29 or the toothing 8 and the plate 6 rest on the wedge 11 in a form-fitting manner. Clamping parts like Screws or the like are not required.
  • the arrangement is particularly easy to adjust and adapt to the prevailing conditions.
  • the bevel 29 on the carrier 5 is omitted.
  • the toothing 8 then runs horizontally.
  • the slope formed by the feet 7 corresponding to the straight line 10 will then have a suitable, different slope.
  • the wedge 11 can be designed differently. At least one of the parts 5, 6 must be provided with a bevel, by means of which the height of the plate 6 is adjusted when the sliding element 11 acting between the parts 5 and 6 is moved.
  • the slope of the slope 29 and the guide 12 is small, a toothing 8 may be unnecessary.
  • the wedge 11 can then be moved continuously on the slope 29; self-locking can be achieved through the slight inclination of the parts 29, 12.
  • the same position of the wedge 11 in each carrier 5 of the warp thread monitor can be achieved in this case, for example, by applying suitable brands.
  • a toothing 8 can be eliminated even with a greater inclination of the bevel 29.
  • the teeth 9 and the corresponding gaps in the bar 5a can be more or less rounded.
  • an eccentric 62 containing bearing disks 63 is mounted in a bore 61 of the carrier 5a in the gearing connection between the carrier 5a and the plate-shaped part 6 as a molded body.
  • the eccentric 62 has a polygonal circumference on which one or more of the feet 7 of the plate-shaped part 6 can be supported. When turning the eccentric 62, the height position can be adjust the plate 6 gradually.
  • an eccentric 62 having a round circumference can also be used, so that a continuous adjustment of plate 6 takes place.
