Definitions

  • a hollow rotary spinning chamber is mounted for rotation about a predetermined axis intersecting an open side of the spinning chamber normal to the general plane of the open side.
  • the spinning chamber has an inner annular surface which surrounds the open side concentric with the axis of rotation which first diverges and thereupon converges in direction inwardly away from the open side.
  • a separating roller is mounted for rotation proximal to the open side and receives fibrous sliver which it separates into the individual fibers thereof.
  • a passage connects the separating roller with the open side of the spinning chamber and has an outlet located at this open side, fibers passing from the separating roller through the passage and issuing from the outlet.
  • Aperture means in the spinning chamber communicates with the interior thereof so as to create in the interior suction when the spinning chamber is rotated. Thereby a stream of air is drawn through the passage, carrying along the fibers into the spinning chamber.
  • Directing means is provided for directing the stream of air with the fibers carried thereby in such a manner that the fibers are deposited on the inner annular surface in a region of the latter which is inwardly proximal to the open side of the spinning chamber.
  • the present invention relates generally to fiber spinning apparatus, and more particularly to an apparatus for spindleless spinning of fibers.
  • the invention relates to an apparatus for continuous spindleless spinning of textile fibers which includes a separating roller receiving fibrous sliver and separating the same into its individual fibers, a rapidly rotating rotary spinning chamber of substantially cup-shaped configuration provided with apertures for evacuating air to thereby create in the interior of the spinning chamber a suction, and a connecting channel connecting the separating roller with the interior of the spinning chamber, as well as means for preventing the deposition of newly entering fiberscoming from the channel-on the yarn which is being formed and thereupon being withdrawn from the spinning chamber.
  • German Patent No. 1,011,790 teaches such a device and reference may be had to this patent for background information.
  • a circular flange is provided formed with needles, which serves as the fiber collecting area. Fibers are prevented from becoming deposited on the yarn being withdrawn from the interior of the spinning chamber, and this is accomplished -by locating the inlet channel for the fibers closely under the surface of the circular fiange provided with the needles, and closely surrounding it with the casing housing the separating roller, so that the yarn may be fed along this casing without any possibility for the fibers to contact the yarn.
  • the separating roller of this device is biased to the axis of the spinning chamber.
  • a further object of the invention is to assure deposition of the incoming fibers on the fiber deposition and collecting surface of the rotary spinning chamber so that they become deposited individually and acquire the desired orientation before reaching the yarn-forming surface where the fibers are formed into the yarn.
  • one feature of our invention resides, in an apparatus for continuous spindleless spinning of textile fibers, in providing a hollow rotary spinning chamber having an open side and being rotatable about a predetermined axis, the spinning chamber comprising an inner annular surface surrounding the open side concentric with the predetermined axis and first diverging and thereupon converging in the direction inwardly of the open side.
  • Aperture means is provided in the spinning chamber communicating with the interior thereof for creating suction in the latter in response to rotation of the spinning chamber.
  • a separating roller is mounted for rotation proximal to the open side and operative for receiving fibrous sliver and for separating the fibers of the same.
  • Passage means has an inlet which receives separated fibers from the separating roller, and an outlet which communicates with the open side so that the separated fibers are drawn by suction through the passage means to the outlet.
  • Directing means is provided for directing a stream of gaseous fluid transversely of the outlet in such a manner as to effect deposition of fibers issuing from the outlet onto the annular surface in a region of the same which is inwardly proximal to the open side of the rotary spinning chamber.
  • the apertures are provided in the spinning chamber remote from the open side so that the inner annular surface that is the portion thereof serving as a sliver surface for the deposited fibers and the portion thereof serving as a collecting surface on which the deposited fibers are collected and formed into a yarn, is free from such apertures. Furthermore, no needles are provided on this inner annular surface.
  • fibers are deposited on the convergent portion of the inner annular surface in a region of the same which is inwardly proximal to the inside of the rotary spinning chamber, and from there move to the junction between the convergent and divergent portions of the inner annular surface, this junction being the area Where the fibers are collected to be formed into a yarn.
  • directing means which serves to direct the stream of gaseous fiuid-that is usually the aspirated airwhich is drawn through the passage means and carries the fibers along from the separating roller to the interior of the spinning chamber, in such a manner that the stream of air and fibers is so deflected that the fibers become deposited on the inner annular surface in the region of the same inwardly proximal to the open side of the spinning chamber, whereupon the fibers automatically straighten out and move-predominantly by rolling movementto the junction between the convergent and divergent portions of the inner annular surface.
  • FIG. 1 is a somewhat diagrammatic sectional elevation illustrating one embodiment of the present invention
  • FIG. 2 is a perspective view showing the directing means employed in the embodiment of FIG. 1;
  • FIG. 3 is a partly sectioned fragmentary illustration of the embodiment of FIG. 1, showing the location of the directing means with reference to other components of the embodiment.
  • reference numeral 1 identifies diagrammatically a fibrous sliver which is supplied in sultable manner to a feed roller 2 which rotates in a cavity C1 of a housing or wall means WM about the axis of rotation 2'.
  • the feed roller 2 supplies the sliver to a separating or carding roller 2a which rotates in a cavity C2 about an axis of rotation 2a.
  • the circumference of the separating roller 2a is provided with separating needles 3.
  • the passage means 6 has an outlet which communicates with the open side of a rotary spinning chamber 5 which is mounted for rotation about an axis *10 extending normal to the general plane of the open side of the spinning chamber 5.
  • the interior of the spinning chamber 5 is identified with reference numeral 4 and the outlet of the passage means 6 communicates with the interior 4.
  • the spinning chamber 4 is provided with a plurality of air evacuation apertures 7 arranged remote from the open side as shown in FIG.
  • air is evacuated from the interior 4 of the spinning chamber through the apertures 7, thereby creating a suction effect in the interior 4 and serving to draw fibers through the passage means 6, together with a stream of air.
  • the air in the interior 4 of the spinning chamber 5 moves in a spiral path from the outlet of the passage means 6 through the interior 4 and out of the apertures 7.
  • the individual fibers issuing from the outlet of the passage means 6 are carried along by this spirally moving airstream and pressed against the inner circumferential or slip surface 8 bounding the open side of the chamber 5, under the influence of centrifugal force.
  • directing means which in the illustrated embodiment is in form of a member 9 illustrated in FIG. 2 and composed of a plurality of substantially fan-shaped air guide fins or ribs 9. It will be seen (compare FIGS. 1, 2 and 3) that the fins 9a extend radially from a hub 9b of the member 9 and are slightly twisted in themselves.
  • the member 9' is mounted stationarily with reference to the spinning chamber 5 (see FIG. 3) and so located inwardly of the open side of the spinning chamber 5 (see FIG.
  • the individual fibers are capable of orienting themselves in planes perpendicular to the axis of rotation of the spinning chamber 5, and to move by rolling or shifting movement to the juncture 11 between the convergent and divergent portions of the inner annular surface 8, at which juncture 11 they form into the yarn 12 which is withdrawn centrally-through an opening in the hub of the member 9from the spinning chamber 5 by the drawing rollers DR to be subsequently wound into a package P.
  • the purpose of the member 9 is to provide in effect a steaming air cushion which prevents the fibers issuing from the outlet of the pas sage means 6 from contacting the undersurfaces of the fins9a, and which results in their defiection onto the region 8a of the surface 8.
  • the fibers cannot become deposited or even come into contact with the fins 9a and the formation of fiber tufts or bundles is avoided.
  • the fibers are thus effectively prevented from moving directly to the juncture 11 and there becoming deposited on the yarn 12 which is being formed.
  • FIGS. 1 3 shows that the fins 9a all extend radially, from the central hub, and that the member 9 is centrally mounted. This assures a simple construction. However, other possibilities exist and will offer themselves to those skilled in the art. It is also desirable that the fins 9a project over the passage means 6 by between substantially 20 and 40. Further covering of the passage means 6 is not generally necessary, and lesser covering would cause irregular streaming conditions.
  • a combination comprising a hollow rotary spinning chamber having an open side and being rotatable about a predetermined axis, said spinning chamber comprising an inner annular surface surrounding said open side concentric with said predetermined axis and first diverging and thereupon converging in a direction inwardly of said open side; aperture means in said spinning chamber communicating with the interior thereof remote from said open side for creating suction in the latter in response to rotation of said spinning chamber; a separating roller mounted for rotation proximal to said open side and operative for receiving fibrous sliver and for separating the fibers of the same; passage means having an inlet receiving separated fibers from said separating roller, and an outlet communicating with said open side so that the separated fibers are drawn by suction through said passage means to said outlet; and directing means having an interrupted surface spaced from and facing said outlet extending transversely thereof, said interrupted surface being operative for directing a stream of gaseous fluid transversely of said outlet in such a
  • said directing means comprises a directing member having a plurality of guide fins.
  • said guide fins being of substantially fan-shaped outline, and wherein said directing member is coaxial with said predetermined axis and said guide fins extend radially of the latter.
  • said directing member being located inwardly of said open side, and said guide fins each having a surface portion together constituting said surface facing towards said outlet of said passage means, and wherein said stream of gaseous fluid is aspirated through said passage means as a result of suction in said spinning chamber and issues from said outlet.
