Definitions

  • ABSTRACT A false selvedge in a shuttleless loom is recovered by continu- Foreign pp Pnonty Dam ously winding the false selvedge under tension on the larger end of a conical bobbin, the wound selvedge movingprogressively- Jan. 20, 1970 France ..700l839 Sively to the narrower end of the bobbin a which i p g 52 US. Cl 139/304, 242/47 fans a swag: Emma [51 Int. Cl. 1 ..D03d 49/20 2 Claim, 4 Drawing Figures 58] Field of Search ..139/29l, 302, 304, 305;
  • the bound threads are separated from the fabric by any suitable means, mechanical or thermal, and thus form a kind of wick, or roving.
  • This wick or roving, thus separated, should have a tension more or less equal to that of the fabric and to obtain this tension, the easiest way is to cause the wick to follow the same course, during its winding, as the fabric.
  • this wick which constitutes a waste, may be allowed to fall straight on to the floor, or indeed be rolled on to a recovery or salvage bobbin.
  • a device for the recovery and removal of a false selvedge in the shuttle-less loom comprises a conical bobbin arranged to be driven in continuous rotation so as to ensure the winding up of the false selvedge under tension, the false selvedge having a stepped distribution on the said bobbin being removed at the side of the said bobbin having the smallest diameter.
  • One embodiment of the invention ensures the automatic elimination of the said false selvedge or selvedges, which after having been separated from the fabric, mechanically or thermally, follow the fabric in the winding up and accumulate, provisionally, under tension, on a conical bobbin whose rotation is controlled by subsidiary means, before being ejected to the floor.
  • FIG. 1 shows a front elevation of a device in relation to the front of a loom with some winding turns of the false selvedge (wick) on the conical bobbin;
  • F IG. 2 shows a side elevation thereof
  • HO. 3 is a view similar to FIG. 1 but with the bobbin half full;
  • FIG. 4 is again a similar view to FIG. I but with the bobbin completely full and a certain length of the wick evacuated to the floor.
  • a support I fixed to the frame 2 of a loom receives an axle 3 integral with a crank 4 which carries a rod 5 on which a conical bobbin 6 can rotate.
  • This bobbin 6 is provided with a disc 7 which ensures its rotation by contact with a pulley 8 itself driven by an existing motion of the machine or by an independent system.
  • the pressure of the disc 7 necessary for its drive by the pulley 8 is caused by the action of a spring 9 attached, on the one hand, to a fixed position member 10, and on the other hand to a position member 11 on the crank 4.
  • the bobbin 6 is positioned laterally by means of stop rings 12 and 13.
  • the bobbin 6 is provided with flat cambered springs 15 and 16 as well as a conical check 17 connecting it to the disc 7.
  • the speed of rotation of the bobbin 6 should be such that it allows a tight winding of the wick 18. This is obtained by means of a suitable speed of the pulley 8, any excess speed being compensated by slipping on the disc 7.
  • the wick is arranged in stepped fashion on the bobbin.
  • the wick 18 being thus stocked on the bobbin has the tendency of being compressed towards the end thereof, on the one hand, due to the conicity of this bobbin and on the other to the inclined check 17.
  • a device for the recovery and removal of a false selvedge in a shuttleless loom comprising a conical bobbin arranged to be driven in continuous rotation so as to insure the winding up of the false selvedge under tension, the false selvedge having a stepped distribution on the said bobbin and being removed at the side of the said bobbin having the smallest diameter, said bobbin being provided with at least one flat spring extending longitudinally thereof and which, under the action of the winding up of the false selvedge, is yieldingly applied against the periphery of said bobbin and insures by reaction the maintenance of the winding on.
  • a device in which the bobbin is provided with a driving disc arranged to be maintained in resilient contact with a driving pulley, said bobbin and driving disc carried by a crank and urged by a spring towards the pulley so that the pulley resiliently supports the driving disc.
