Definitions

  • the present invention concerns a spring loading device for twin pressure rollers, especially for drawing frames of spinning machines, in which the pressure rollers are positively connected with the lower roller in axis parallel manner by a supporting arm which is journalled merely on the lower roller pertaining to said rollers.
  • Fig. 1 illustrates partly in section a side view of a spring loading device according to the present invention.
  • Fig. 2 is a front view of Fig. 1.
  • Fig. 3 is a longitudinal section through a roller rod with adjusting device for the length of the drawing frame.
  • Figs. 4 and 5 show some details of the device according to the present invention.
  • the primary feature of the present invention consists in that the holding arm for a pressure roller pair is pro vided with guiding and holding means for the holding arm of a second pressure roller pair by means of which guiding and holding means the last mentioned holding arm is in a force locked and axis parallel manner guided and held with regard to a second lower roller.
  • the spring loading device according to the invention which is of particular importance in connection with drawing frames of wet spinning machines makes use of the known arrange ment according to which a pressure roller is directly positively connected with the lower roller cooperating there with.
  • an arrangement which comprises at least two pressure roller means which are spaced from each other and by a single pressure urged holding means are positively and in a form closed manner connected with the respective lower rollers pertaining thereto. More specifically with reference @to Figs.
  • each delivery roller means consists of two rollers l spaced from each other and supported and rotatably interconnected by a shaft which is provided with a circular groove 2 into which a holding member 3 is fitted so that the member 3 cannot move in axial direction.
  • the axial immovability of the roller means may also be assured in a different manner.
  • Each feed roller means for the roving F similarly consists of two rollers supported and rotatably interconnected by a shaft 36 which has mounted thereon a holding member 5.
  • the holding member 5 likewise immovable in axial direction because the holding members 3 and 5 are connected with each other by rigid guiding means 6.
  • This guiding means may be connected to the holding member 3, whereas it is arranged so as to be able to slide in a bore of the member 5.
  • the pressure roller means with rollers 7 and 8 respectively pertaining to the lower rollers l and i are held in position by a rod or bar 11 which acts both upon the shafts 9 and 10 respectively rotatably interconnecting the respective pressure rollers 7 and 8.
  • This rod 11 is under the influence of pressure by tension springs 12 (Figs. 1 and 5) which are preferably mounted in the holding member 3 and the tension of which is conveyed to the rod 11 through rods 13 and an eccentric 15 which is rotatable about the bolt 14 mounted at the end of said rods 13.
  • the pressure rollers 7 as Well as the pressure rollers 8 are form and force locked with the lower rollers 1 and 4 respectively pertaining thereto.
  • a special holding member in form of a yieldably journalled pin or bolt 20 is provided.
  • the said bolt 20 is yieldably journalled in the holding member 3 and extends through a longitudinal slot 21 of the rod ll.
  • the extension of said slot in the longitudinal direction of the rod 11 is greater than the diameter of the .bolt 20, while one edge 22 of said slot is rounded in order to furnish a certain play for the member 20 in case that the diameter of the cylinders changes due to wear or regrinding.
  • the divided holding mechanism according to the invention in which the individual holding members 3 and 5 are interconnected by means of a rigid guide 6 allows a relative movement of these holding members so that the distance a and thus the length of the drafting field can be varied.
  • Fig. 3 illustrates how the distance between the roller pairs 1, 7 and 4, 8 can be adjusted relative to each other.
  • one rod 23 is guided in each of the roller stands 24- of the machine, i.e. the bearings for shaft 35 (one only being shown in Fig. 3).
  • the lower end of said rod 23 is provided with a thread '25 which is threadedly engaged by a nut 26 which latter "is not movable in axial direction of the rod 23.
  • the rotation of the nut 26 is effected by means of a shaft 27 and a helical wheel 28 mounted thereon and meshing with corresponding teeth 29 on the periphery of the nut 26.
  • the shaft 27 may extend along the entire length of the machine and, at the individual locations of the bearings of the drafting rollers (roller stands), may respectively be provided with helical gears so that when rotating the shaft 27, all rollers 4 of the entire machine may simultaneously be adjusted for purposes of varying the distance :1, because these rollers are at the other end of the rod 23 journalled in the portions 39 of the roller stands.
  • the lower rollers 1 and 4 are not subjected to any material bending stress.
  • the bearings of the rollers in the roller stands are subjected only to the stress caused by the weight of the rollers and the pressure-producing devices for the spinning stations located between said roller stands, so that the number of the roller stands to be provided in a machine can be considerably reduced while the distance between the roller stands can be increased.
  • the loading device according to the invention which, as stated above, is completely closed in itself and requires a minimum of space, furthermore makes it possible directly therebehind, for instance by means of cover sheets 31 (Fig. l) to cover the entire machine against humidity and accumulation of dirt, because no weight mechanism, spring mechanism or lever mechanism protrude in the direction toward the line AA (Fig. l) which represents the axis of symmetry of a spinning ma chine equipped with a device according to the present invention.
