Definitions

  • a rotary spinning chamber is rotatable about a predetermined axis and has an open side.
  • a peripheral wall of the rotary spinning chamber has an inner circumferential fiber-collecting surface which extends inwardly from the open side and surrounds the axis of rotation.
  • Outlet apertures are provided in the peripheral wall extending from the surface to the outer side of the wall, and wall means defines a closed compartment adjacent the outer side and communicating with these apertures.
  • the present invention relates generally to spinning machines, and more particularly to a spinning machine of the type utilizing spinning chambers for spinning fibers into yarn.
  • the particulate impurities which have a greater mass and frequently greater size than the fibers, are capable of passing over the groove and under the influence of the centrifugal force resulting from highspeed rotation of the spinning chamber, they leave the interior of the latter through ventilation openings which are provided in the circumferential wall of the spinning chamber for the escape of air, the latter being necessary to produce an underpressure in the spinning chamber which exerts a suction effect drawing the fibers into the interior of the spinning chamber.
  • Another approach to the problem at hand is to constitute the interior spinning space of the spinning chamber by two at least axially traverseable rotary bodies, of which the inner one is provided with ventilation pen-openings.
  • the inner body is arranged in a cylindrical portion of a hollow formed in the outer body interrupted at its circumference by cleaning openings.
  • This device does not fulfill the requirements which are made. It is very intricate in its construction and thus expensive to produce. Aside from this its very intricacy causes complications during machine operation because the speed of rotation of the spinning chamber is very high and the smallest imbalance of the two bodies causes vibrations which are objectionable for various reasons. Also, the two bodies cannot be displaced with reference to one another by even the slightest amount-as may occur during the high-speed rotation-without bringing about such imbalance and vibrations.
  • a concomitant object of the invention is to provide such a construction which is simple and hence not only inexpensive but reliable in its operation.
  • a spinning machine in a combination comprising a rotary spinning chamber which is rotatable about a predetermined axis and which has an open side.
  • the spinning chamber has a peripheral wall provided with an inner circumferential fiber-collecting surface which extends inwardly from the open side and which surrounds the axis of rotation.
  • Outlet apertures are provided in the peripheral wall extending from the surface to the outer side of the wall, and wall means defines a closed compartment adjacent the outer side and communicating with these apertures.
  • the wall means may define an annular channel with the peripheral wall of the chamber and it is advantageous that the annular open side of this channel faces in the same direction as the open side of the spinning chamber itself.
  • the wall means surrounds a front portion of the peripheral wall, that is the portion closer to the open side of the chamber, whereas the rear portion is surrounded by additional stationary wall means which defines an annular clearance with the rear portion of the peripheral wall and which clearance is separated from the annular channel by a labyrinthine seal. Air-escape openings are then provided in the rear portion of the peripheral wall and communicate with this clearance so that air can escape into this clearance from the interior of the rotating spinning chamber. It is also advantageous to provide a cover which covers both'the open side of the spinning chamber and the annular open side of the annular channel.
  • FIG. 1 is a fragmentary vertical section through one embodiment of the invention.
  • FIG. 2 is a view analogous to FIG. 1, illustrating an additional embodiment of the invention.
  • reference numeral 1 identifies a housing or spinning body for a rotary spinning chamber whose basic construction and operation are known from the art.
  • the body 1 is mounted on the frame of a non-illustrated spinning machine and it will be understood that such a machine will have a plurality of the units illustrated in FIG. 1.
  • a shaft 3 is freely rotatably mounted in a bearing 2 and has secured at one end a pulley 4 through which rotation is imparted to the shaft 3.
  • the latter in turn is connected with the rotary spinning chamber 5 so that the chamber can be rotated about the axis of rotation along which the shaft 3 extends.
  • the spinning chamber 5 is mounted in a recess or hollow 6 of the body 1 and provided on the inner side of its circumferential wall which bounds an interior space 7, with a fiber-collecting surface 8.
  • An open side 10 is provided on the chamber 5 and the interior of the latter conically diverges towards the fibercollecting surface 8, with a fiber-sliding surface 11 extending from the open side 10 to the collecting surface 8.
  • a plurality of outlet or cleaning apertures 12 are provided which extend from the collecting surface 8 to the outer side of the circumferential wall of the spinning chamber and there communicate with a closed annular channel or compartment 13 in form of a circumferential recess 131 defined between the outer circumferential wall of the spinning chamber 5 and annular circumferential wall means 14 which in the illustrated embodiment is of one part with the outer circumferential wall of the spinning chamber.
  • the wall means 14 could be suitably secured to the outer circumferential wall of the spinning chamber, but in any case it will rotate with the latter as illustrated.
  • the annular open side 132 of the recess 131 advantageously faces in the same direction as the open side 10 of the inner space 7 of the spinning chamber 5, because this is advantageous from the point of view of removing impurities from the recess.
  • a cover 16 is provided which extends across the open side 10 and the annular open side 132 and which in the exemplary embodiment of FIG. 1 is so configurated as to constitute the fiber-separating body 17 of the fiber-separating device which is diagrammatically illustrated and which is of known construction. Attention is directed to the fact that the lid or cover 16 is provided with two concentric grooves 18 into which the marginal portions of the peripheral wall and of the wall means 14 extend to form so-called labyrinthine seals. It is pointed out that no air flow should take place in the channel 13 during operation of the machine.
  • a carding roller 19 with a toothed outer surface is diagrammatically illustrated as being rotatably mounted in the fiber-separating body 17, and a similarly diagrammatically illustrated feed roller 20 with a pressing block 21 are provided which supply fibrous sliver 33 to the carding roller 19 which separates the fibers of the sliver and advances them via a channel 22 to the interior 7 of the spinning chamber 5.
  • a separator 23 is provided in the cover 16 located in the axis of rotation of the spinning chamber 5 and having a withdrawing opening 24 for yarn 25 which is withdrawn by the diagrammatically illustrated withdrawing rollers 26 and then wound by a winding-up roller 27 onto a bobbin '28.
  • the space 6 in which the rotary spinning chamber 5 is mounted for rotation is subdivided into two chambers or portions by a labyrinthine-seal wall 31.
  • a front portion 61 of this space constitutes the channel 13, being defined between the outer circumferential or peripheral wall of the spinning chamber 5, a portion of the wall of the body 1 and the labyrinthine-seal wall 31.
  • a rear portion 62 is separated from the channel 13 or portion 61 by the labyrinthine seal and communicates with the airescape openings 9 of the chamber 5.
  • the cleaning or outlet apertures 12 communicate with the portion 61 as before and it will be understood that the labyrinthine-seal wall 31 is intended to prevent the flow of air between the portions 61 and 62 or vice versa.
  • the impurities become deposited on the inner surface 32 bounding the portion 61 and thus they do not influence the distribution of forces acting upon the spinning chamber 5, so as to for instance to cause an imbalance of the latter.
  • the other features of the embodiment of FIG. 2 which incidentally is somewhat more advantageous than that of FIG. 1 are the same as those shown in FIG. 1.
  • the fibrous sliver supplied by the feed roller 20 to the carding roller 19 is separated into its constituent fibers which are advanced through the channel 22 and enter the interior 7 of the spinning chamber 5. They become deposited on the surface 11 under the action of the underpressure within the spinning chamber 5 due to the escape of air through the outlet openings 9, as well as under the action of the centrifugal force resulting from rotation of the spinning chamber 5. Under the action of this centrifugal force the fibers slide along the surface 11 until they reach the collecting surface 8 where they become deposited in form of a fibrous ribbon which is wrapped by contact with the trailing end of the yarn 25. This is already known and it will be appreciated that in this manner the yarn 25 is formed.
  • the impurities which enter the chamber 5 together with the fibers are of small dimension and thus can pass through the apertures 12 into the magazine or. channel 13. Because the fibers are of course larger-i.e. longer-they cannot pass into and through the apertures 12 so that they remain in the interior of the chamber 5 and are uninfluenced by the presence of the apertures 12. It will be appreciated that no air flows through the apertures 12 because the channel 13 is relatively air-tight by the labyrinthine seal provided for this purpose, so that the fibers cannot be influenced by an undesired air flow and will become converted into a yarn in the normal manner.
  • the spinning of the fibers is in no way disturbed, and at the same time impurities of higher specific weight than the fibers can escape under the influence of centrifugal force through the outlet or cleaning apertures 12 into the channel 13 where they become accumulated.
  • the continuous formation of the fibers into a yarn, and the continuous withdrawal of the yarn are not influenced or disturbed in any way, and the formation or build-up of impurities on the surfaces 11 and 8 is completely avoided with an elimination of the concomitant difficulties which would arise otherwise from such a build-up.
  • a spinning machine in combination, a rotary spinning chamber rotatable about a predetermined axis and having an open side, said spinning chamber comprising a peripheral wall having an inner circumferential fiber-collecting surface extending inwardly from said open side and surrounding sa1 axis; an-
  • escape openings provided in said peripheral wall axially spaced from said open side; outlet apertures provided intermediate said air-escape openings and said open side and extending from said surface to the outer side of said wall for venting to said outer side of contaminants which enter said spinning chamber with the fibers to be spun; and wall means defining a closed compartment adjacent said outer side and communicating with said apertures for receiving the vented contaminants therefrom.
  • peripheral wall having a first annular marginal portion surrounding said open side, and said wall means having a second annular marginal portion outwardly spaced from and surrounding said first marginal portion.
  • annular channel having an annular open side surrounding and facing in the same direction as said open side of said spinning chamber.
  • said peripheral wall having a first annular wall portion closer to, and a second annular wall portion farther from said open side, and wherein said wall means surrounds said first annular wall portion; further comprising additional wall means surrounding said second annular wall portion and defining therewith an annular clearance; and wherein said air-escape openings are in said second annular wall portion and communicate with said annular clearance.
  • said cover having two concentric annular grooves, and said first and second annular marginal portions being respectively received with clearance and freedom of rotation in the inner and outer one of said two concentric annular grooves.
