Definitions

  • This invention relates to a balloon control ring for controlling ballooning in the spinning, doubling and twisting of yarn.
  • An object of the present invention is to attain a good twisting finish without involving such phenomenon as occurrence of a molten yarn and appearance of a nap and to control ballooning well while passing a yarn at high speed in the spinning, doubling and twisting processes of yarns of synthetic fibers.
  • FIG. I is a plan view of a balloon control ring, showing an embodiment of the present invention.
  • FIG. 2 is a side view corresponding to FIG. 1;
  • FIGS. 3A to 3E are sectional views of respectively different rings
  • FIG. 4 is an expansion plan of the inner surface of the ring shown in FIG. 1;
  • FIG. 5 is a diagram of the characteristic curve of a balloon control ring according to the present invention in the spinning process
  • FIG. 6 is a diagram of the distributions of the single yarn strength
  • FIG. 7 is a diagram of the distributions of the single yarn elongation percentage.
  • FIG. 8 is a diagram of the characteristic curve of a balloon control ring according to the present invention in the twisting process.
  • a balloon control ring shown in FIG. 1 is for spinning in the case of the Z-twist (right-hand lay).
  • the balloon control ring (R) is made annular by the use of a wire rod being circular in section. It is crooked in corrugation perpendicularly to the plane of the ring, in other words, along the axis of the ring.
  • the corrugation includes three ridges I, 2 2,, and 3 which are formed in a line at equal spacings in the circumferential direction.
  • End parts 4 and 8 of the ring (R) are laid one over the other with a clearance therebetween so as to define a yarn guide port 9.
  • the extremity of the end part 8 is made a protuberance for the yarn introducing guide at the yarn inlet.
  • the three-ridge corrugation of the ring (R) begins from the ridge 1 and leads to a trough 5 and further to the ridge 2.
  • the section between the ridge 2 and the ridge 2, is made uniform in height or made a continuous body in order to facilitate securing a mounting member 10.
  • the corrugation leads to a trough 6, the ridge 3, a trough 7 and the end part 4 in the order mentioned.
  • the end part 4 defines the yarn guide port 9 jointly with the end part 8 of the ridge I, and the corrugation leads to the first ridge.
  • the ring is formed.
  • 6 designates the inclination which the oblique side of the ridge defines to the ring plane, that is, the inclination of the ridge.
  • Symbol (X) denotes the height of the ridge.
  • the number of the ridges formed in a line is three, the inclination 9 is 12, and the yarn guide port is provided at the part of the ridge.
  • the number of the ridges is suitably selected to be at least two.
  • the yarn guide port may also be provided at the trough part or at an intermediate part between the ridge and the trough.
  • the height (X) of the ridge can be suitably selected.
  • the ridges need not always be equally spaced.
  • the inclination 6 is suitably selected within a range of 5 30 in dependence on the number of the ridges.
  • the wire rod of the circular section as shown in FIG. 3A is employed in order to form the ring (R)
  • the wire rod may also have a flat section shown in FIG. SE, a V-shaped section shown in FIG. 3C, a stranded wire section shown in FIG. 3D, a crushed stranded-wire section shown in FIG. 3E, etc. (as regards the sectional shapes C and E, the right side as viewed in the figure constitutes a Contact surface with the yarn).
  • the wire rod such material as metal and synthetic resin is used.
  • the ring is suitably subjected to quenching, plating, nitriding or any other surface treatment.
  • the balloon control ring (R) stated above is fixed to the mounting member 10 by welding or bonding at its outer peripheral part or by any other suitable means, and is attached to a machine frame through a mounting hole 11 by the mounting member 10.
  • the balloon control ring of the present invention is constructed as described above. Description will now be made of the state in which the yarn is slid and rubbed on the balloon control ring.
  • the balloon control ring (R) is installed on the machine frame by the mounting member I0 and its mounting hole 11 so that the central point of the balloon control ring may lie on the axis of a spindle. Thereafter, the yarn is caused to run. The yarn is twisted and taken up while the ballooning induced by the high speed rotation of a traveler is being controlled to decrease by the ring (R) and the spinning-out tension is decreasing. Meantime, the yarn turns around on the inner peripheral surface of the balloon control ring (R) at high speed as it is depressing the peripheral surface. Let it be supposed that the turning direction of the yarn is the direction of arrow (P) in FIG. 1 and FIG. 4 and that the yarn initiates its contact with the ring (R) at the point of the ridge 1.
  • the yarn slidingly descends along the slant surface of the ring and reaches the point of the trough 5. Subsequently, it ascends along the slant surface and reaches the point of the ridge 2. It runs through the part 2 2,, which, as previously stated, is made uniform in height in order to facil itate securing the mounting member 10. Next, the yarn descends along the slant surface and reaches the point of the trough 6. It ascends to reach the point of the ridge 3. It descends to reach the point of the trough 7. Finally, it ascends along the slant surface and reaches the initial point of the ridge 1. Thus, one revolution is terminated. The yarn turns round while repeating the proceeding.
  • the amount of delivery of the yarn in the period in which the yarn moves by the unit length (Y) corre sponding to (Y.) or (Y is equal to the quotient obtained by dividing the amount of delivery per minute by the product between double the number of ridges of the ring and the number of revolutions per minute of the traveler. Accordingly, it is generally slight.
  • the height (X) of the ridge as bestows the upward and downward sliding is associated with the length (Y, Y of the base of the ridge.
  • the height (X) of the ridge is represented by tan 6 multiplied by the length (Y,) or (Y which is V2 of the length of the base of one ridge.
  • the second-mentioned length being obtained by dividing the circumferential length of the ring by the number of ridges. Good results are achieved within a range of the inclination 6 of the ridge from 5 to 30. Especially, the best result is often achieved in the vicinity of 10".
  • FIG. 5 shows the characteristic curve of the embodiment of the present invention It indicates that, in case where rings each being 3 mm in the wire diameter. 50 mm in the inside diameter and three in the number of ridges were used in the spinning process of a polyester fiber, the maximum number of revolutions 14,500 rpm. was obtained at an inclination of the ridge 12 without generation of a molten yarn and at good twisting finish.
  • FIGS. 6 and 7 illustrate measured values of the single yarn strength and the single yarn elongation percent age, respectively.
  • the measured values were obtained when the quantities were measured at an upper part, a middle part and a lower part of the chase (one stroke width ofthe ring rail in the vertical direction).
  • Columns I and l] in FIGS. 6 and 7 correspond to the case of employing the priorart balloon control rings made of the flat wire rod and the circular hollow wire rod, respectively, and columns Ill the case of employing the balloon control ring according to the present invention.
  • both the single yarn strength and the single yarn elongation percentage exhibit excellent values, and they are very small in dispersion.
  • FIG. 8 shows the characteristic curve of another embodiment, not shown, in the twisting process of a polyester fiber tyre cord. It indicates that, in case where a ring being 8 mm in the wire diameter, having a comparatively large inside diameter of mm and provided with five ridges was used, the maximum number of revolutions 7,000 rpm. was obtained at an inclination of the ridge 10 without generation of a molten yarn and at better twisting finish as in the previous embodiment than in the cases of employing the prior-art balloon control rings.
  • the yarn is not slid and rubbed in a manner to draw one point in the lateral direction as is in the prior-art balloon control ring, but it is always slidingly contacted and moved downwards and upwards again and again over a large vertical width.
  • the frictional resistance with the yarn is therefore extremely low as compared with that in the prior-art.
  • the twist lowering factor in the balloon control ring portion is approximately 15 percent in the prior-art, it can be reduced to approximately 8 percent in accordance with the present invention. This renders the twisting finish good, and prevents the yarn from severing.
  • the frictional heat is always diffused in the vertical direction, the generation of a molten yarn is preventable. Where the direction of rotation of the balloon is the opposite to that shown in the drawing, the vertical sliding relative to the yarn becomes the opposite.
  • a balloon control ring comprising a ring member made of a wire rod whose portion to be contacted with a yarn has a round shape, said ring member being formed into a corrugation having at least two ridges protruding in the axial direction thereof, and a mounting member for supporting said ring member on a machine frame.
  • a yarn guide port is formed by outwardly protruding one end of said wire rod constituting said ring and by laying it over the other end with a clearance therefrom.
