Definitions

  • the device according to the present invention removes these disadvantages. It is provided with a thread and fly suction device havinga central casing with channels which are provided with an orifice slot each extending within the range of the drawing mechanism at several working points, and is characterized by suction conduits which are provided within the orifice slot of the channels and the suction openings of which are located closely to the feed drawing rollers.
  • the suction conduits extend over an entire drawing mechanism system between two stands or bearing points.
  • the suction conduits may have a constant cross section or may be formed diffusion-like.
  • a means is connected to the orifice slot into which the suction conduit extends, which converts speed energy to pressure.
  • the suction conduit thereby can be extended, freely supported, into the suction orifice without the aid of any packings.
  • FIGURE 1 is a diagrammatical cross-sectional view taken upon section line II of FIGURE 2 through a spinning frame illustrating the thread suction device.
  • FIGURE 2 is a partial diagrammatic front elevational view of the spinning frame shown in FIGURE 1 illustrating the thread suction device.
  • FIGURE 3 is a partial cross-sectional view upon an enlarged scale showing the drawing mechanism together with the suction means cooperating therewith.
  • FIGURE 4 is a side view of a detail of the drawing mechanism.
  • FIGURE 5 is a View similar to FIGURE 1 showing a modified construction of the suction mechanism.
  • FIGURE 6 is a partial elevational front view of the construction shown in FIGURE 5.
  • FIGURE 7 is a view similar to FIGURE 1 of a further modification of the suction apparatus.
  • FIGURE 8 is a front elevationalview of the structure shown in FIGURE 7, and
  • FIGURES 9 and 10 show cross-sectional views of two modifications of the suction conduits.
  • a frame 1 of a spinning frame is provided with longitudinally extending roller beams 2, to which the stands 3 are screwed which support in a known way the driving rollers of a drawing mechanism 6, particularly the feed drawing rollers 4 upon the pressure roller supporting arm 5.
  • a known suction casing 8 is supported with symmetrically arranged intake channels 7.
  • the casing 3 ends in the upper part of the machine with a fan 5 therein and a filter lit).
  • Suction conduits 12 extend into the orifices 11 of the channels 7, said conduits being of smaller cross section since the size thereof is limited by the upper and lower limitation of the orifice l1 and by the height of the supporting feet 13. Because of technical flow reasons, a median altitude level is preferred.
  • the suction conduit 12 itself extends, at the beginning, parallel to the direction of flow within the orifice of the channel 7. Then the conduit 12 is slightly bent upwardly and extends recti lineally towards the feed drawing roller i.
  • Thesuction opening 1410f the suction conduits 12, as shown in FIGURE 3, widens slightly at the drawing roller 4 towards the bottom and the top and is arranged in such a way, that air is circulated around from both sides, i.e. from the front and towards the back, with nearly the same amount of air.
  • the suction conduit 12 relative to the feed drawing roller 4 is so positioned, that the tangent to the feed drawing roller coincides with the center line of the conduit 12. Because of such positioning any broken thread is within the zone of the highest turbulences in conduit 12 and thereby the highest frictional forces are effective thereon.
  • the width of the conduit 12 corresponds to the distance between two successive stands 3 on which the drawing rollers are mounted.
  • the suspension of the suction conduit 12 at its suction end which is located near the roller 4 is accomplished by means of offset pin 15, which, on one hand, is welded to the lower side of the conduit 12 or is soldered or fastened in any way, and on the other hand is clamped between two springs l6 and 117, which are secured below to the front surface of a stand 3 by means of a bolt 18.
  • the spring 16 which is adjacent the stand is provided at its upper end with a recess 19 for the insertion of the pin 15, while the other spring 17 is slightly bent towards the front at the top, in order to facilitate an easy insertion of the pin 15 from the front. In this way the conduit 12 can be easily, without the aid of any tools, detached towards the front and again brought to its working position.
  • a diffuser 20 which retards the flow, i.e. converts the speed energy partially into pressure.
  • a short distance dif fuser is suitable whose cross section widens gradually (FIG. 3).
  • the graduated wall 20' of the diffuser is mounted by means of standards 20" on the frame 1.
  • a flap 2.1 is provided which is secured by means of a screw 23 to a shaft 22 which extends along the machine.
  • the shaft 22 rotates in supports 24 secured to the frame 1 of the machine.
  • a lever 25 which is fixedly connected to the shaft 22 and which is articulated to a lever 26, serves for swinging the flap 21 towards the positions shown in dash lines or dot and dash lines.
  • the flaps are only adjusted to about /a, i.e. to the position shown in dash lines.
  • the space between and below the beams 2 is empty and can be used for installing the casing 8', as shown in the modification of FIG- URES 5 and 6.
  • the expansion of the casing 8' (FIG- URE 6) within the longitudinal direction of the machine is so chosen that the casing can be installed between two intermediate plates 27 forming the frame. In such case, nothing has to be changed at the thread suction conduit 12 which extends to the front drawing roller 4.
  • FIGURES 7 and 8 illustrate a further embodiment of a casing which is placed at the bottom. It is provided in its upper part at the range of the spindles 29 with vertical walls 30 in order to then taper at half of its height against a suction aggregate (not shown) in a side view (FIG- URE 8) which is surrounded by a filter 31.
  • a further horizontal suction conduit 32 is symmetrically arranged which enters with undiminished width into the casing 28 which has not yet tapered at this point.
  • the cross section can be also formed difiusor-like, if this is desired for technical reasons of the flow.
  • FIGURES 9 and 10 show modified forms of the suction conduit.
  • the suction conduit 33 has a conical diffuser and in FIGURE 10 the conduit 34 is provided with a graduated difiuser 34.
  • the orifice slot 11 of the channel 7 can, instead of being open, as shown, be closed with the exception of the entry of the suction conduits 12.
  • the sudden enlargement of the crosssection at the entry of the suction conduits 12 into the larger orifice slot 11 acts as an impact ditlusor.
  • the dust suction efiect is not present.
  • a thread suction means on a spinning and twisting frame comprising drawing means having feed drawing rollers, a centrally located suction casing, and a flat substantially rectangular suction duct having a suction opening extending uniformly over a plurality of spinning and twisting stations and over the entire width of said duct located adjacent said feed drawing rollers and having an outer opening in the rear end, substantially as large as said suction opening and extending into said central suction casing.
  • a thread suction means on a spinning and twisting frame comprising drawing rollers, a centrally located suction casing having an intake channel projecting toward said drawing rollers, said channel having an outer opening formed as a slot extending over a plurality of spinning and twisting stations of the frame, and a flat substantially rectangular suction duct having a suction opening extending uniformly over a plurality of spinning and twisting stations and over the entire width of said duct located adjacent said drawing rollers and having an outer opening in the rear end, substantially as large as said suction opening and located in the outer opening of said intake channel.
  • a device wherein the rear end of said suction duct extends with play into the outer opening of said intake channel so that an upper and a lower part of said opening remains free.
  • a device wherein a difiuser means is provided in said intake channel which transforms speed energy into pressure and which constantly expands in the direction of the air flow.
  • suction duct has substantially a constant cross section and widens shortly before said suction opening.
  • suction duct expands towards its rear end diifusion-like.
  • suction 3 duct expands step-wise.
  • suction duct extends rectilineally from said suction opening and then is provided with a bend and extends into said intake channel in the longitudinal direction of the same.
  • suction duct has a straight section and the center line thereof forms a tangent to the lower drawing roller which is correlated to said suction duct.
