Definitions

  • a flyer for spinning machines is disclosed as having a pair of legs extending parallel to the spindle axis, with 5 at least one of these legs having a series of bristles extending therealong to entrain fiber fly and retain the fiber fly in the bristles.
  • the bristles may be removably mounted as a unit on the leg, and the leg may be formed with air flow apertures or slots therethrough.
  • the exit end'of the air flow slot or aperture is closed by a screen or the like for further entraining and retaining fiber fly.
  • This invention relates to spinning machines and, more particularly, to a novel and improved roving or fly frame for spinning machines particularly effective in preventing fiber fly being entrained in thread which is being spun or wound.
  • An object of the invention is to provide an improved flyer for a spinning machine whereby this disadvantage is obviated.
  • Another object of the invention is to provide an improved flyer for an improved spinning machine and wherein at least a portion of the flyer is so formed that fly fibers coming into the flyer area, during rotation of the flyer, will be entrained and retained on such surface area against the influence of forces tending to dislodge the fly fiber such as, for example, the wind or draft due to flyer rotation.
  • a further object of the invention is to provide an improved flyer for a spinning machine of the type having a pair of legs and a generally U-shaped configuration, and wherein at least one leg is so formed as to entrain and retain fly fibers entering the flyer area.
  • Yet another object of the invention is to provide an improved flyer for spinning machines, of the type mentioned, in which the mentioned flyer surface may have a partially interrupted cross section.
  • a further object of the invention is to provide an improved flyer for spinning machines, of the type mentioned in which at least one leg of the flyer has bristles along its front edge and/ or side surface.
  • Still another object of the invention is to provide an improved flyer for spinning machines, of the type mentioned, and in which a bristle-like front edge and/or side surface are provided on one leg by means of a removable strip or backing carrying bristles.
  • a further object of the invention is to provide an improved flyer for spinning machines, of the type mentioned, in which at least one leg comprises two spaced webs defining a longitudinal slot through the leg and closed along the trailing edge of the leg by an air permeable means on which fiber fly will settle.
  • Another object of the invention is to provide a flyer for spinning machines, of the type just mentioned, in which the side surfaces of the two webs defining the slot are provided with bristle-like elements.
  • FIG. 1 is a front elevation view of a flyer embodying the invention and rotatably mounted on a spindle;
  • FIG. 2 is a side elevation view of the flyer shown in FIG. 1;
  • FIG. 3 is a cross sectional view of one leg of the flyer shown in FIGS. 1 and 2;
  • FIGS. 4, 5 and 6 are cross sectional views of a flyer leg, illustrating alternative embodiments of the invention.
  • a flyer 1 is illustrated as an inverted U-shaped element rotatably mounted on a spindle shaft 2.
  • Flyer 1 has a hollow leg 3, in the usual manner, through which the thread is passed.
  • Leg 3 has, at its lower end, the customary finger 4 which feeds the thread to the bobbin.
  • the other leg 5 of the flyer is formed in accordance with the invention, along at least its vertically extending portion or portion which is parallel to the flyer axis.
  • leg 5 is provided with a bristle-like element 6 along its vertical portion. Fiber fly impinging on flyer leg 5 is entrained in the bristle-like element 6. The impact pressure resulting from the rotation of the flyer at a relatively high angular velocity presses the fly fiber into the bristles. Thereby, the fly fibers are retained and, furthermore, newly impinging additional fiber fly can also be entrained in the bristles. The device thus prevents the fiber fly from becoming loose at an undesired time, in the form of flocks or lumps, and from being entrained in the thread.
  • the improved flyer in accordance with the invention is useful not only in preventing deterioration of the thread by entrainment of fiber fly but also in preventing the detrimental effects on the yarn caused by yarn breakage, particularly at the finger and at the bobbin.
  • a flyer constructed in accordance with the invention When a flyer constructed in accordance with the invention is used, a large portion of the yarn, flocks and lumps resulting from yarn breakage will be entrained and retained by the flyer leg, such as the leg 5, and will thus be prevented from entering into adjacent bobbins.
  • the element 6 mounted in the leg 5 comprises bristles 7 in a bristle holder or backing 8.
  • holder 8, carrying the bristles 7, is removably mounted in leg 5.
  • FIG. 4 illustrates the cross section of a flyer leg constructed in accordance with a different embodiment of the invention.
  • the cross section of the leg is interrupted so that the leg, at least over its vertically extending part, comprises a pair of webs 9 and 10 which are spaced apart radially of the flyer axis to define a longitudinal slot extending circumferentially of the flyer axis.
  • the rear or trailing edge of the flyer leg is provided with an airpermeable element 11 at least partially closing the slot extending between the webs 9 and 10.
  • the fiber fly settles on element 11 due to the air flowing through the elongated siot between the webs 9 and 10.
  • the cross section of the leg is interrupted so that the leg, at least over its vertically extending part, comprises a pair of webs 9 and 10 which are spaced apart radially of the flyer axis to define a longitudinal slot extending circumferentially of the flyer axis.
  • the rear or trailing edge of the flyer leg is provided with an air
  • exterior surfaces of webs 9 and 10 may be provided with bristle-like elements 12 and 13.
  • the cross section of a flyer leg is interrupted to provide, along the vertical portion of the flyer leg, a radially directed elongated slot dividing the leg into webs 14 and 15, of which the web 14 may be termed a leading web and the web 15 the trailing web, considered in the direction of rotation of the flyer.
  • Webs 14 and 15 have their outer surfaces provided with bristle-like elements 16 and 17.
  • the fiber fly is entrained essentially only on the outer surfaces of the flyer leg, where it is retained by the bristle-like elements 16 and 17
  • the flyer leg along its vertical portion, is formed with an elongated slot therethrough defined by two webs 9 and 10' whose interior surfaces are configured to form a jet extending in the direction of rotation of the flyer.
  • the trailing end of this jet is at least partially closed by an air-permeable element 11', in the same manner as described for the embodiment of the invention shown in FIG. 4, and the fiber fly entering through the jet passage is retained on the element 11'.
  • leg 3 of the flyer 1 also could be constructed in the same manner as the leg 5.
  • a flyer for spinning machines of the type rotatably mounted on a spindle and including a pair of spaced legs extending substantially parallel to its axis of rotation at substantially equal radial spacings to either side of such axis, with one leg serving to feed thread therealong to a bobbin rotatable about the spindle axis between the flyer legs, the improvement comprising a series of bristles extending along at least a portion of the length of at least one leg, to entrain fiber fly entering the area of rotation of the flyer to retain said fiber fly against entrainment in the thread.
