Definitions

  • a hollow rotary spinning chamber has a shaft fixed therewith and defining an axis of rotation for the chamber.
  • Drive means engages the shaft for rotating it and thereby the spinning chamber.
  • Magnetic means maintains the shaft in a predetermined operative position in lieu of bearings,
  • the present invention relates generally to spinning machines, and more particularly to machines for ringless spinning of fibers. Still more particularly the present invention relates to spinning machines using rotary spinning chambers.
  • Machines of the general type in question herein are already known. They use a generally cup-shaped rotary spinning chamber which is rotated at high speed and onto an inner circumferential wall of which fibers in carded and separated state are deposited in known manner, whereupon these fibers become connected with one another under the influence of centrifugal force and can be withdrawn as a continuous thread from the spinning chamber.
  • Such spinning chambers must be rotated at high speeds which requires that they are mounted in special highspeed bearings. Consequently all spinning chambers of the type which have heretofore become known do, in fact, utilize high-speed bearings by means of which the spinning chambers are mounted for rotation. Such bearings, however, are very expensive to manufacture because of the precision requirements which are made of them. On the other hand, they must be constantly and precisely lubricated with special lubricants and despite this they are subjected to considerable heating and friction so that their lifetime is very short. Finally, in operation these bearings are rather noisy.
  • one feature of the invention resides in a device for ringless spinning of fibers which comprises, briefly stated, a hollow rotary spinning chamber and a shaft which is fixed with this spinning chamber and which defines an axis of rotation for the same.
  • Drive means engages the shaft for rotating the same and thereby the spinning chamber, and magnetic means maintains the shaft in a predetermined operative position in lieu of bearings.
  • FIG. 1 is an axial sectional elevation illustrating one embodiment of the invention
  • FIG. 2 is a top-plan view of FIG. 1;
  • FIG. 3 is a view similar to FIG. 1 and illustrating a further embodiment
  • FIG. 4 is a view similar to but illustrating the embodiment of FIG. 3;
  • FIG. 5 is a view similar to FIG. 1 illustrating yet an additional embodiment
  • FIG. 6 is a view similar to FIG. 2 but of FIG. 5, and also taken in a partial section on line VI-VI of FIG. 5;
  • FIG. 7 is another view similar to FIG. 1 but illustrating still a further embodiment of the invention.
  • FIG. 8 is a section taken on line VIII-VIII of FIG.
  • FIG. 9 is a view similar to FIG. 7 illustrating still another embodiment of the invention.
  • FIG. 10 is a section on line X-X of FIG. 9;
  • FIG. 11 is a view similar to FIG. 9 illustrating still another embodiment of the invention.
  • FIG. 12 is a view similar to FIG. 7 illustrating an additional embodiment of the invention.
  • FIG. 13 is a section on line XIII-XIII of FIG. 12;
  • FIG. 14 is also a view similar to FIG. 7 but illustrating a final embodiment of the invention.
  • FIG. 15 is a section on line XV-XV of FIG. 14.
  • reference numeral 2 identifies a spindle mounted on or in the body or housing 1.
  • the spindle carries connected thereto for rotation with it a hollow carding roller 3 of known construction, and is provided at its free end with a pulley 4, for instance for engagement by a drive belt or the like (not illustrated) so that the spindle may be rotated about its axis.
  • the carding roller is provided on its inner circumferential surface with two annular beads or projections 5 and 6 which are circumferentially continuous.
  • a holder is identified with reference numeral 9 and a recess is provided in the separating or carding roller 3 for the bearings 11, 12 of the holder 9.
  • the outer circumferential surface of the carding roller 3 is provided with a carding configuration, that is it is of such configuration that it cards or separates fibrous sliver fed to it into its constituent fibers.
  • a carding configuration that is it is of such configuration that it cards or separates fibrous sliver fed to it into its constituent fibers.
  • this is achieved by providing the exterior of the carding roller 3 with the covering 10 having saw-tooth external configuration, although needles, pins or the like could also be provided.
  • Holder 9 is secured to a lid 14 in which a rotating spinning chamber 15 is mounted.
  • a shank or shaft 16 is rigid with the spinning chamber 15 and provided with an annular projection 17.
  • Bearings 11 and 12 of the holder 9 have a certain clearance, in conjunction with the member 13, permits the necessary adjustment of the spinning chamber 15 and its axial retention.
  • the annular projection 17 of the shaft 16 extendsinto a corresponding notch provided in the member 13 and the shaft, which extends through the bearings 11, 12 is in contact with the inner side of the heads 5 and 6.
  • retaining means is provided in form here of permanent magnets 18 and 19 which in this embodiment may be of annular or circular shape.
  • the magnets are each adjacent to the shaft 16 and their coincident poles are juxtaposed.
  • a pole shoe 21 is provided interposed between the juxtaposed poles, and two further pole shoes 20, 21 each cooperate with the respective poles of the permanent magnets 18 and 19. All of the pole shoes extend towards the shaft 16, thus maintaining the same in predetermined operative position. In other words, the shaft 16 is maintained in its predetermined operative position and can deviate from this position only by the clearance value determined by the bearings 11 and 12, that is to a negligible extent.
  • bearings 11 and 12 are not journals for the shaft 16 but only serve to determine the permissible deviation of the shaft 16 from its permanent position.
  • the shaft is thus capable of rotation without being journalled in bearings-keeping in mind what has just been said about the purpose of the bearings 11 and l2and the expense of providing high-speed bearings, of lubricating them, and the noise associated with the operation of such bearings are thereby eliminated.
  • FIGS. 3 and 4 differs from the embodiment of FIGS. 1 and 2 primarily in that the bearings 11 and 12 of FIGS. 1 and 2 are omitted and the permissible deviation of the shaft 16 from its predetermined position is defined by the illustrated annular disc members.
  • Like elements are again identified with like reference numerals.
  • the projection 17 on shaft 16 extends into a recess 28 provided on an annular disc member 27.
  • a holder 25 is mounted on the lid 14 and pairs 26, 26' and 27, 27' of annular disc members are mounted ON shafts 23, 24 respectively, which in turn are held by the holder 25.
  • the holder 25 is so arranged that in normal operative position of the shaft 16 the rotating shaft will not be in contact with the disc 26, 26 and 27, 27'.
  • the latter that is the discs just mentioned, serve only to prevent shaft 16 from misalignmentthat is from deviating from its predetermined position-during starting and braking of the carding roller 3.

  • the purpose and operation of this embodiment is, of course, the same as before.
