Definitions

  • a polishing ring with individual textile strips constituting a polishing border which comprises a carrying ring, and a plurality of textile-strips surrounding the carrying ring in about U-shape.
  • the textile-strips have multi-layer legs, and means are provided for connecting together the multi-layer legs outside of the carrying ring.
  • Each of the U-legs forms foldings by multiple twisting of the textilestrips.
  • the present invention relates to a polishing ring with individual textile-strips forming a polishing border and disposed in U-shape about a carrying ring, the multi-layer legs of the textile-strips being connected together outside of the carrying ring by a closing seam or the like.
  • Polishing rings and polishing discs are known, the border of which comprises a long, passing through band member, which is disposed in folds such, that the peripheral end face of each textile layer is arranged about zig-zag and meander-like, respectively (see for example US. Pat. No. 2,004,623).
  • polishing rings are known, the border of which is formed of a plurality of small members produced by narrowly wound textile strips, which small members are disposed U-shaped in successive arrangement about the carrying ring, whereby the U-legs extending radial direction on the outside of the carrying ring is gripped by means of a closing seam (see US. Pat. No. 2,489,193).
  • the U-legs disposed geometrically in one plane permit, however, likewise the creation of a joint.
  • the present knob-like U-legs are very solid due to the winding up. A deep penetration of the work piece is, thus, also here not possible, so that substantially, the previously mentioned drawbacks occur, first of all, when the polishing rings are joined together to a polishing drum.
  • the twisting provides for the afterwards again returning U-leg of the textile-strip-section, a somewhat bouquet-like structure with deep folds, which point from the twisting axis into many directions and which, depending upon the direction of penetration of the work piece, permits an active participation of all fold layers nearly to the base of the polishing border.
  • the obtained short fold layers in the apex zone of the U-shaped formation which fold layers widen slowly to the free U-leg end, are favorable due to the thereby created wedge form of the mounting of such polishing rings.
  • the fixing of the apex zone can take place in any dilferent manner and by hot ironing, respectively.
  • the density of such polishing rings can be adjusted to the prevailing application.
  • the irregular arrangement of the textile-stripsections, originating from the twisting brings about a line-free polish, even in connection with work pieces consisting of softer working material.
  • FIG. 1 is a side elevation of a polishing ring designed in alccordance with the present invention, shown schemat- 1ca y;
  • FIG. 2 is an elevation of the end face of the polishing rlng
  • FIG. 3 is a textile-strip-section prior to the twisting
  • FIG. 4 is an elevation of a twisted textile strip section
  • FIG. 5 is an elevation of a textile strip section with the U-legs brought into parallel position
  • FIG. 6 is a section along the lines 66 of FIG. 5;
  • FIG. 7 is a section along the lines 7--7 of FIG. 5;
  • FIG. 8 is a section along the lines 8-8 of FIG. 1.
  • the polishing ring designed in accordance with the present invention comprises a carrier ring 1 which consists of wire, a ring of synthetic material, or the like.
  • the polishing body is formed of a plurality of separately twisted textile-strip-sections 2. These are material sections of a conventional smooth textile strip 3. The latter comprises bias cut textile fabric. In order to obtain a strip length capable of being wound up, several textile strip members are joined by gluing, or as shown in the embodiment of FIG. 3, by a seam N.
  • the seam guide is disposed inclined to the textile strip-side border 3'.
  • Each textile strip section 2 is twisted about the longitudinal axis xx and folded over the carrier ring 1 so as to have a generally U-shaped form including a bight portion 2' and two substantially equally long legs 2', 2".
  • the bight portion as seen in FIG. 7, is more tightly twisted than the legs, as seen in FIG. 6, said legs becoming less tightly twisted at progressively further locations away from the bight.
  • the twisted individual-sections shown in FIG. 5 are aligned on the carrying ring 1 in series and disposed on top of each other.
  • the U-legs are connected on the outside of the carrying ring 1 by a seam 4.
  • the polishing ring is suitably impregnated. Such impregnation thereby performs a particular task, namely to glue the threads of the textile-strip-sections which are shorter, whereby the threads are better held in connection.
  • the polishing ring in accordance with the present invention permits the suspension of the work piece to be polished up to the base 5 of the border.
  • a polishing ring with individual textile-strips constituting a polishing border comprising:
  • each of said strips having a generally U-shaped form including a bight portion and two substantially equally long legs, said bight portion being more tightly twisted than said legs, said legs becoming less tightly twisted than that of said bight portion at progressively further locations away from said bight;
  • polishing ring as set forth in claim 1, wherein said textile strips comprise a bias-cut fabric.
  • polishing ring as set forth in claim 1, wherein the textile fabric of said polishing border is impregnated.
