Definitions

  • ABSTRACT QF THE DISCLQSURE rl ⁇ he air escape openings of a rotary spinning chamber are spaced to prevent clogging by fibers.
  • the present invention relates to rotary spinning chambers of the type in which textile fibers are supplied to a circular collecting surface and are spun on the same into a twisted yarn which is delivered through a central stationary delivery channel to a pair of transporting rollers.
  • the shorter fibers are frequently simultaneously caught at both ends by two escape openings so that they are held on the intermediate wall portion without being able to escape together with the air passing through the escape openings.
  • fibers are accumulated on the wall portion where the escape openings are provided, and gradually clog the escape openings, preventing the escape of air and causing reduced air flow into and out of the spinning chamber, resulting finally in the spinning of a yarn of poor quality.
  • Another object of the invention is to dispose the air escape openings of a rotary spinning chamber in such a manner that fibers cannot be caught at both ends in adjacent escape openings.
  • the present invention relates to a rotary spinning chamber having an inlet for fibers and air, and a wall formed with a plurality of escape openings for air and fibers driven outward by the centrifugal force.
  • the escape openings are spaced from each other such a predetermined distance that one end of a fiber blown toward the wall cannot enter an escape opening when the other end of the fiber has entered another escape opening. In this manner, clogging of the escape openings by fibers having the ends thereof located in two escape openings is prevented.
  • the distance between adjacent escape openings is greater than one-third of the standard length of the fibers.
  • the distance between two adjacent escape openings is selected so that when one end of any one of the shorter fibers enters an escape opening, the other end of the iiber is located on the wall between the respective escape opening and the next adjacent escape ICC opening, and is safely blown out of the escape opening in which its end is located.
  • FIG. 1 is a fragmentary schematic axial sectional view illustrating an embodiment of a spinning chamber provided with the improvement of the invention.
  • FIG. 2 is a fragmentary plan view of the embodiment, partially shown in cross section.
  • a spinning chamber 1 is carried by drive shaft 2 and rotated about its axis.
  • the spinning chamber has a circular collecting surface 6 formed by two intersecting frusto-conical surfaces and located in the region of the greatest diameter of the spinning chamber.
  • a stationary body 12 has a portion 13 projecting into the spinning chamber, and is formed with an inlet channel 4 through which fibers 5 are supplied into the interior of the spinning chamber to be spun at the collecting surface 6 into a yarn 7 which is transported by a pair of rollers 9 through a delivery channel 8 disposed coinciding with the axis of rotation of spinning chamber 1.
  • Winding means not shown, wind up the yarn 7 to form a package 10.
  • the spinning. chamber has circumferentially spaced outlet channels 3 which open on the inner surface of the spinning chamber in circumferentially spaced air escape openings 11 located in a plane perpendicular to the axis of rotation of the spinning chamber.
  • the centrifugal force moves air through the escape openings and outlet channels, and sucks air and fibers 5 through the inlet channel 4.
  • the fibers are spun on the collecting surface 6 into the yarn 7, a portion of which revolves with the spinning chamber, while another portion passing through the delivery channel 8 to the transporting rollers 9, is twisted.
  • the fibers 5 are obtained by a known and conventional combing roller which combs the fibers out of a sliver. Most of the Ifibers are of a standard length, while other fibers are shorter. Those fibers which are not spun into the yarn on collecting surface 6 should escape through the escape openings 11 and outlet channels 3 in order to prevent clogging of the spinning chamber.
  • the distance a between adjacent escape openings 11 is selected so that one end of a short fiber blown toward a wall portion 11a, cannot enter an escape opening when the other end of the fiber has already entered another escape opening.
  • the distance a between two adjacent escape openings 11 is greater than one-third of the standard length of the fibers S supplied into the spinning chamber. Fibers of shorter length than distance a cannot be caught simultaneously in two adjacent escape openings 11 so that the main reason for the clogging of the escape openings is eliminated, and disturbances of the spinning operation due to clogging of the outlet channels is prevented. Fibers having a greater length than one-third of the standard length of most supplied fibers, have sufficient mass to be thrown onto collecting surface 6 by the centrifugal force, while shorter fibers have a smaller mass and tend to fioat in the spinning chamber toward openings 11.
  • a short fiber 4 which was not held on the collecting surface 6, or did not reach the same, can enter only with one end into an escape opening 11, and is immediately and quickly blown by the stream of air passing through the respective escape opening an outlet channel out of the spinning chamber.
  • the distance a between adjacent circumferentially spaced escape openings 11a will be selected in accordance with the length of the fibers produced by the particular combining device, and will be selected so that the greatest possible number of short fibers, which are not spun into a yarn, cannot enter with both ends into adjacent escape openings.
  • a rotary spinning chamber having an inlet for fibers and air, and a wall formed with a plurality of escape openings for air and fibers driven outward by the centrifugal force, wherein said escape openings are spaced from each other such a predetermined distance that one end of a fiber blown toward said wall cannot enter an escape opening when the other end of the fiber has entered another escape opening whereby clogging of said escape openings by fibers having the ends thereof located in two escape openings is prevented.
  • Rotary spinning chamber as dened in claim 1 coinprising means for supplying fibers having a predetermined standard length into said spinning chamber; and wherein said predetermined distance between adjacent escape openings is greater than one third of said standard length of said fibers.
  • Rotary spinning chamber as defined in claim 1 comprising means for supplying standard fibers and shorter fibers into said spinning chamber; and wherein said predetermined distance is selected so that one end of any one of said shorter fibers whose other end enters one of said escape openings is located on said wall between said one escape opening and the escape opening adjacent the same so that the respective shorter liber is blown out of said escape opening.
  • Rotary spinning chamber as defined in claim 1 wherein said wall has a frusto-conical inner surface in which said escape openings are located circumferentially spaced from each other said predetermined distance.
  • Rotary spinning chamber as defined in claim 4 wherein said wall has outlet channels extending in radial direction with respect to the axis of rotation of said rotary spinning chamber, and terminating at said inner rusto-conical surfaces in said escape openings.
  • Rotary spinning chamber as defined in claim 5 wherein said escape openings and said outlet channels have a circular cross section.
