Definitions

  • ABSTRACT OF THE DISCLOSURE A carding roller rotating in a predetermined direction, a feed for continuously supplying fibrous sliver to the carding roller so that the sliver is converted thereby into oriented fibers which travel with the roller in the predetermined direction, and a rotary spinning chamber having an inlet proximal to the carding roller and so arranged that the oriented fibers traveling therewith are automatically removed from the carding roller and enter the inlet of the spinning chamber.
  • the present invention relates to the treatment of fibrous material. More particularly, the invention relates to a method of treating oriented fibers obtained by carding or combing fibrous sliver. Still more specifically, the invention relates to a method of doffing the oriented fibers from the working surface of a fiber-orienting instrumentality.
  • the invention also relates to an apparatus for carrying out the aforementioned method.
  • fibers suitable for this so-called windless spinning process are supplied in form of sliver, that is in nonoriented state in which they cannot undergo the spinning process, they must first be treated by being separated and properly oriented.
  • the sliver is fed to a combing or carding instrumentality, usually a rotating cylindrical roller, which is provided with projecting needles by which the sliver is engaged and which comb the fibers, that is separate and orient them.
  • the present invention provides a method by which the dolfed fibers are transferred directly to the collecting surface adjoining the inlet of a rotary spinning chamber.
  • we provide a method of treating fibrous material wherein fibrous sliver is continuously fed into a first portion of a predetermined path. This sliver is carded during movement thereof in this first portion whereby the sliver is separated into a mass of oriented fibers. Further in accordance with the invention, the thus separated fibers are continuously spun into a yarn in a second portion of the path which is contiguous with the first portion and located immediately downstream thereof.
  • a apparatus for carrying out the above method can comprise, in accordance with a further feature of the invention, a fiber-separating member traveling in a predetermined direction, and feed means for continuously supplying fibrous sliver to such member so that the fibers of this sliver are separated by the member during the travel thereof in such predetermined direction.
  • the novel apparatus comprises a rotary spinning chamber having an inlet which is proximal to the member and which is so arranged with reference to the latter that the separated fibers traveling with the member are automatically removed from the same and enter the inlet of the rotary spinning chamber.
  • FIG. 1 is a vertical section taken through an apparatus in accordance with the present invention
  • FIG. 2 is a section taken on the line lI-II of FIG. 1;
  • FIG. 3 is a top-plan view of the embodiment illustrated in FIG. 1, certain features having been omitted for purposes of clarity;
  • FIG. 4 is a view similar to FIG. 1, but showing another embodiment of the invention.
  • FIG. 5 illustrates yet a further embodiment of the invention in a vertically sectioned view.
  • the novel apparatus comprises a rotatable drive shaft 1 on which there is fixedly mounted a combing or carding roller 2 having an. external circumferential working surface 3 provided, as shown in FIG. 2, with a plurality of needles 4 orothe'r suitable projections.
  • the roller 2 is mounted within a housing 9; specifically, it is located in a cavity bounded by an inner peripheral surface 23 which is juxtaposed with the exterior surface 3 of roller 2 in such a manner as to define therewith a substantially annular clearance 22.
  • a feed roller 5 Arranged in close proximity to the exterior surface 3 of roller 2 is a feed roller 5 which is mounted on a drive shaft 6 and located in a recess of housing 9 which communicates with a substantially funnel-shaped inlet 7 provided in the housing as well as with the clearance 22 in such a manner that the cylindrical surface of each roller 5 is tangential to both.
  • a cover 10 At the top of the housing 9 there is firmly secured a cover 10 and located within this cover is a spinning chamber 11 mounted for rotation about a vertical axis by means of its hollow shank 16 which terminates in a belt pulley 17 firmly secured thereto. Extending through the shank 16 is a yarn-w-ithdrawing tube 18 through which a yarn 19 may be withdrawn from the interior of chamber 11 under the action of a withdrawing means comprising a pair of driven withdrawing rollers 20 located upstream of the tube 18.
  • the cavity of the rotary spinning chamber 11 is internally bounded by a fiber guide surface 14 which diverges radially upwardly and merges with a fiber-collecting surface 13 on which fibers introduced into the chamber 11 are deposited under the influence of centrifugal force resulting from rotation of the chamber 11, to thus form a cohesive ribbon which is thereupon withdrawn in form of the yarn 19.
  • the spinning chamber 11 is provided with one or more ventilating apertures 12 and the cover 10 is similarly provided with at least one ventilating aperture 21.
  • the inlet of chamber 11 faces downwardly towards the housing 9 and is bounded by a peripheral edge 15.
  • the upper surface of housing 9, insofar as it is located beneath the cover 10, is provided with an annular recess which, as is evident from FIG. 1, at one point breaks through the wall of housing 9 to communicate with the clearance 22.
  • a substantially circular projection 27 is formed within this recess and extends slightly above the upper surface of housing 9.
  • the spinning chamber 11 is so positioned that the projection 27 actually projects upwardly into the interior of chamber 11 and that one segment of the peripheral edge 15 of chamber 11 extends downwardly below the projection 27 into the clearance 22 and, in fact, into close proximity with the working surface 3 of carding roller 2. Such proximal relationship is established, as clearly evident from FIG.
  • the arrangement of the edge 15 of spinning chamber 11 proximal to the surface 3 of roller 2 is such that the fibers will be forced to lift off the surface 3 when advancing into the region of the edge 15 upstream thereof.
  • Sliver 8 coming from a (non-illustrated) source of supply is engaged by the rotating feed roller 5 and drawn through the inlet 7 of housing 9 into the clearance 22.
  • this clearance it is advanced between the wall surface 23 on the one hand and needles or other projections 4 on surface 3 on the other hand and, by moving along the initially narrowing clearance 22, it is firmly equipped between the two juxtaposed surfaces with the result that the needles 4 separate and orient the fibers of the sliver, which then emerge in the widening portion of clearance 22 as a stream 25 of oriented fibers.
  • the fibers of stream 25 move into the area of clearance 22 in which the suction effect prevailing in the spinning chamber 11 is effective.
  • the fibers are thus lifted off the surface 3 over the edge 15 and onto the surface 14; in other words they are doifed. If any of the fibers adhere firmly enough to surface 3 to resist dofling, they will move underneath the edge 15 of spinning chamber 11 and continue on to the feed roller 5 where they will be admixed with newly entering sliver. Of course, any fibers which for some reason become lodged on the edge 15 itself, will be aspirated into the interior of chamber 11 as a result of the aforementioned suction effect.
  • FIG. 4 shows a somewhat different embodiment which is, however, generally similar to the one shown in FIGS. 1-3. It differs from these essentially in the fact that a fluid stream is directed through the clearance 22 in the direction opposite the rotation of roller 2, in order to assist in dofiing of the fibers.
  • the fluid which is evacuated from the interior of the spinning chamber 11 through the ventilating ejectors 12 thereof is not permitted to escape to the ambient atmosphere, as in the case of the preceding embodiment where this is accomplished by letting the fluid escape through the aperture 21 of cover 10.
  • the cover 10 forms an annular space 29 with the spinning chamber 1 1, such space communicating with the ventilating apertures '12 of the latter.
  • a return channel 28 connects this space 29 with the clearance 22 immediately downstream of the edge 15 of spinning chamber 11, as indicated by reference numeral 30.
  • fluid evacuated from the interior of spinning chamber 11 is introduced into the clearance 22 in counterfiow to the stream of fibers 25, which is oppositely the direction of rotation of the roller 2.
  • This fluid stream passes beneath the edge 15 of spinning chamber 11 and moves between the surface 3 of roller 2 and the fibers 25 upstream of the edge 15, thus serving to assist in the dofling of the fibers, by helping to lift them onto the edge 15 and the surface 14.
  • any well known means for regulating a flow of fluid through the channel 28 can be added to the embodiment of FIG. 4.
  • FIG. 4 is particularly advantageous not only because of its increased doffing efficiency, but also because it provides a substantially closed circulatory system for the fluid stream produced within the spinning chamber 11, an arrangement which is advantageous if a plurality of spinning units are used in conjunction with a single machine.
  • FIG. 5 is [largely self-explanatory and simply shows that it is possible to utilize the novel invention in an even more efficient manner by having a single carding roller 2 serve two spinning chambers.
  • two feeds are provided, each of which supplies one of the spinning chambers, and it is thus possible not only to utilize more effectively the available surface area of the circumferential surface of roller 2, but also to continue operation of one feed and its associated spinning chamber if a ma lfunction should force shut-down of the other spinning chamber and feed.
  • this concept is not limited to the use of only two spinning chambers with their associated feeds, but also encompasses the use of a greater number of such chambers and feeds.
  • Device for treating fibrous material comprising a fiber-separating member travelling in a predetermined direction; feed means for continuously supplying fibrous sliver to s'aid member so that the fibers of such sliver are separated by said member during travel thereof while being advanced thereby in a predetermined path; and a rotary spinning chamber having an inlet which is proximal to said member and comprises a receiving portion extending into said path so that the separated fibers travelling in said path with said member are automatically removed from the latter and enter directly into said inlet of said rotary spinning chamber.
  • said fiberseparating member comprises a working surface to which the separated fibers adhere
  • said inlet of said rotary spinning chamber is bounded by wall means having an edge portion located closely adjacent to said Working surface extending into said path, and onto which the separated fibers adhering to the latter are automatically transferred directly from said working surface.
  • said member is a substantially cylindrical rotary carding roller having an outer circumferential working surface; and further comprising housing means having an inner peripheral surface spacedly surrounding said working surface and defining therewith an annular passage which constitutes lsai'd path, said feed means communicating with said annular passage at a first point thereof, and said rotary spinning chamber having an inner rotary surface bounding said inlet and extending transversely of said annular passage at a second point which is angularly spaced from said first point.
  • said spinning chamber rotates about an axis tangent to said Working surface and comprises rotary wall means bounding said inlet and having an edge portion located closely adjacent to said working surface and provided with said inner response to rotation of said carding roller.
  • said spinning chamber comprises fluid-exhaust passage means communicating with the ambient atmosphere for producing a suction effect in said spinning chamber in response to rotation of the latter about said axis, whereby to facilitate transfer of said separated fibers onto said edge portion.
  • said means comprises channel means communicating with said exhaust passage means, said stream of fluid thus being constituted by fluid exhausted from said spinning chamber.
  • a device for treating fibrous material comprising 'a fiber-separating member traveling in a predetermined direction and having a fiber-engaging surface adapted to engage fibrous sliver and to separate the fibers of such fibrous sliver during travel of said fiber-separating member in said predetermined direction; guide means located 'adja'cent to said fiber-separating member and having a face juxtaposed with but spaced from said fiber-engaging I surface of said fiber-separating member, said face of said guide means defining with said fiber-engaging surface a fiber gap in which the fibers advance during travel of said fibersparating member in said predetermined direction; and a rotary spinning chamber having an inlet and a movable wall bounding said inlet and projecting into said tfiber gap, and said movable wall moving through said fiber ga'p in a direction substantially transversal to said predetermined direction so as to collect the fibers advancing in said fiber gap and to transfer the thus collec'ted fibers into said movable spinning chamber.
