Definitions

  • ABSTRACT OF THE DISCLOSURE A traveller for use with ring spinning and twisting machines in which a wire of substantially uniform crosssection having a width and thickness of a ratio of more than four to one is soconstructed that the portion from the contacting point between the traveller and ring to the point of its leg portion is provided with a fiat section and the remaining arcuate portion is defined by an inner con- .vex surface and a concave outer surface with a yarn being arranged to run in contact with said convex surface.
  • This invention relates to travellers for use on rings spinning and twisting machines, and more specific-ally to travellers having a construction adapted for use for the spinning and twisting of yarns composed particularly of man-made fibers such as viscose rayon, synthetic fiber, and their blends.
  • the friction existing between the yarn and traveller generates heat which causes a fusion of fibers, especially so in the case of man-made fibers having a low softening point, thus resulting in the production of yarns having a low strength.
  • a wide area of the traveller contact with the ring makes it possible to stabilize the behaviour of the traveller in running and hence reduce yarn breakage, while a wide area of heat radiation permits the smooth diffusion of the heat caused by such frictional contact between the traveller and ring, thereby preventing occurrence of a fused and hence a fuzzy yarn, particularly in the case of man-made fibers.
  • C-shaped and vertical travellers for the spinning and twisting operations and these travellers were basically of circular, fiat rectangular or semi-circular cross-section or a combination thereof, namely, a circular cross-section at the thread guiding zone but of flat cross-section at the ring contacting zonerEach of these travellers has, as every one familiar with a spinning mill knows, its own advantage and dis advantage.
  • a traveller of circular crosssection is advantageous in that it presents a small frictional resistance at its thread-guiding zone, while being disadvantageous in that it has a small area of contact between the traveller and the ring and hence a small area of heat radiation, thereby resulting in a greater burn and shorter life of the traveller.
  • a traveller of flat rectangular cross-section will provide a wide area of contact between the traveller and the ring and hence of heat radiation, while suffering from the dis-advantage that it presents a great frictional resistance at its thread-guiding zone.
  • travellers of semi-circular crosssection and of a combined type as previously mentioned have an improved feature over the other two types in certain aspects, such travellers are objectionable in that the manufacture of a material wire and the formation of the traveller involve considerable difficulties.
  • a principal object of the present invention is to provide a traveller of an improved construction which is not only easy to manufacture in large quantities and at a lower cost since it can be shaped continuously from a wire of uniform configuration, but also is capable of overcoming various disadvantages encountered with the use of the conventional travellers.
  • FIG. 1 is a view front elevation of a traveller incorporation my invention
  • FIG. 2 is a sectional View taken on line X-X of FIG. 1, the view looking in the direction of the arrows,
  • FIG. 3 is a perspective view of the traveller in the running position, and showing the relative position of the traveller and ring,
  • FIG. 4 is a perspective view of the traveller illustrated in FIG. 1,
  • FIG. 5 is a view in side elevation of a C-shaped traveller, showing another embodiment of my invention.
  • FIG. 6 is a view in front elevation of a vertical traveller, showing still another embodiment of my invention.
  • FIG. 7 is a view in side elevation of the traveller illustrated in FIG. 6, and
  • FIG. 8 is a view taken on Y-Y of FIG. 6, the view looking in the direction of the arrows.
  • FIGS. 1-4 show a C-shaped traveller of the invention formed by a wire of flat, uniform cross-section having a Width and a thickness ratio of more than 4 to 1 or preferably 7 to 1.
  • the C-shaped traveller T consists of a leg portion 2, a bow portion 3 and a yarn is arranged to run so as to keep in contact with the belly side of the blow portion 3.
  • the bow portion 3 is so constructed that the inner surface of the portion, approximately 10 above the horizontal axis line HH, i.e., the inner surface of the arcuate portion extending from 4 to 5 of contact point 1 of a ring R and traveller T (corresponding to bearing center B of the ring shown in FIG. 3) is defined by a gentle curve convex surface S of a trough-like shape to permit the smooth running of a yarn, and the surface opposite to the curved surface S is defined by a curved concave surface S.
  • the side surface of the portion is not edgy like that of a flat wire so that the frictional resistance of a fiber can be reduced to a sufficient degree.
  • the leg portion 2 having a plain flat section is of a larger width than the bow portion, thereby permitting, as shown in FIG. 2, a stable and high-speed runing of the traveller with no danger of the traveller being tilted or distorted during running, and at the same time, offering a larger area of heat radiation by virture of its larger circumferential length.
  • terminal ends 6 of its leg portion 2 into an arcuate shape so as to prevent the same from coming into contact with the ring in an irregular running.
  • leg portion 2 Since the traveller is capable of being tilted in running, the terminal ends of leg portion 2 may be twisted in advance as shown in FIG. 5, so that the contacting area is further enlarged to ensure a uniform frictional wear of the traveller.
  • This invention also may be adapted to a vertical traveller as shown in FIG. 6.
  • a traveller of thin flat cross-section provided with a trough-like shape at its thread guiding zone ensures a lowering of the center of gravity thus resulting in a stabilized running position of the traveller.
  • a traveller for use with ring spinning and twisting machines including a wire of a substantially uniform cross-section having a width and a thickness of a ratio of substantially more than four to one, said wire being so constructed that the portion from the contacting point between the traveller and ring to the point of its leg portion is provided with a flat section and the remaining arcuate portion is defined by an inner convex surface and an outer concave surface, with a yarn being arranged to run in contact with the convex surface of said remaining arcuate portion said flat section having greater width than said bow section to provide greater stability at contact point between ring and traveller.
  • a traveller for use with ring spinning and twisting machines including a wire of substantially uniform crosssection having a width and a thickness of a ratio of substantially more than four to one, said ring being so constructed that the portion from the contacting point between the traveller and ring to the point of its leg portion is provided with a fiat section and the remaining arcuate portion is defined by an inner convex surface and an outer concave surface, and the entire body of said traveller including said arcuate portion being of C-shape, with a yarn arranged to run in contact with the convex surface of said arcuate portion and said flat section having greater width than said how section to provide greater stability at contact point between ring and traveller.
  • a traveller for use with ring spinning and twisting machines including a wire of substantially uniform cross-section having a width and a thickness of a ratio of substantially more than four to one, said wire being so constructed that the portion from the contacting point between traveller and ring to the point of its leg portion is provided with a flat section and the remaining arcuate portion is defined by an inner convex surface inside and an outer concave surface, said flat section having greater width than said bow section to provide greater stability at contact point between ring and traveller and the entire body of said traveller including said arcuate portion being of a vertical type, with a yarn arranged to run in contact with the convex surface of said arcuate portion.
