Definitions

  • This invention relates to drafting devices of the type used in textile machines and more particularly to magnetic drafting elements having a novel plastic-type housing.
  • a typical roll would have a cylindrical magnet, a hollow sleeve portion to house the magnet, pole pieces, pole piece extensions, and gudgeons.
  • rubber cots of uniform thickness are provided to tit on a reduced portion of the sleeve. Because of the necessity of assuring even pressure of the rolls on the sliver each element of the roll necessarily was carefully machined to provide concentricity of the pieces. Moreover, a grinding operation was necessary after the final assembly to further insure concentricity. With the exception of the cots each piece would be of strong metal. As can well be imagined, such a construction was extremely expensive.
  • the major object of this invention is to provide a magnetic top roll, of extremely simple construction, which has built-in concentricity without the necessity of machining.
  • this present invention comprises a permanent magnet and permanently aiiixed or integrally formed pole pieces embedded in a molded plastic shell.
  • FIG. l is a side elevation in section of one embodiment of the invention.
  • FIG. 2 is a view of FIG. 1 taken along the line 2-2;
  • FIGS. 3 and 4 are views similar to FIG. l of alternative embodiments of the invention.
  • a cylindrical permanent magnet is provided.
  • a pole piece 12 is provided which is permanently afxed to the magnet 10 as is in FIG. 1 by means of solder or other such means, or which is an integrally formed ange portion of the magnet 10 as in FIGS. 3 and 4, and which has a larger diameter than that of the center portion or body of the magnet 10.
  • a plastic, nonmagnetic material is provided as a shell about the circumference of the magnet 10 at 14 leaving the pole pieces exposed however on their circumferential surfaces.
  • Plastic 16 also is provided at the end portions of the magnet of a reduced diameter relative to that of the pole pieces 12. Cots 18 of rubber or the like, of uniform thickness, are mounted on the platsic end portions 16 and extend radially outward farther than the pole pieces 12.
  • the pole pieces and magnet are first assembled, if they are separate.
  • the nished magnet and pole pieces are then inserted into a mold having locating dimensions corresponding to the diameter of the pole pieces and the length between the outer radial surfaces of the pole pieces. If gudgeons are to be provided, they are also aligned in the mold.
  • the plastic material is then injected into the mold.
  • the plastic used snould have low shrinkage values to prevent cracking and checking.
  • this invention greatly simplifies the construction of magnetic top rolls. A plurality of elements is eliminated. A greater degree of accuracy is achieved in attaining concentricity of elements than was heretofore possible and several expensive grinding operations are eliminated.
  • pole piece concentric thereof and permanently aixed thereto, said pole pieces being of equal diameter, greater than the diameter of said magnet, and each of said pole pieces having an exposed circumferential surface
  • a cot of rubber-like material of uniform thickness mounted on each of said end portions, said cots being of equal thickness and having inner diameters equal to the diameters of said end portions.
  • pole pieces are integral portions of said magnet forming radially extending fianges thereof.
