Definitions

  • the invention relates to a polishing body consisting of a central support body and a surrounding polishing ring made of impregnated textile material in the form of layered upright and possibly folded fabrics and / or nonwovens and / or cords with its edges, edges or ends so engages the workpiece so that it penetrates into the polishing body.
  • these impregnated polishing bodies are disadvantageous insofar as the polishing costs are considerable due to the short service life and the poor utilization of the polishing pastes due to poor adhesion to the polishing bodies. For this reason, the polishing bodies have already been impregnated, see e.g. GDR - WP 10 47 47 and DE-AS 28 39 725.
  • the known textile polishing articles can be impregnated both before shaping on the running textile web and by appropriate treatment of the finished shaped polishing article.
  • the textile material of the polishing body is impregnated uniformly over an entire area.
  • the polishing bodies produced as described have an increased service life and, in some cases, also an improved port processing and thus utilization of the polishing pastes, however, do not meet the wishes and requirements of industry due to the greatly reduced adaptability.
  • the invention has for its object to provide polishing body of the type described above, in which the textile material is pressed in the direction of its main plane with fabric edges or cord ends on the workpiece, which is sufficiently soft and supple despite the impregnation to allow the workpiece to be immersed and the polishing body to rest well on spatially curved workpiece surfaces and still guarantee a long service life.
  • This object is achieved according to the invention by an area-wise interrupted and / or screened impregnation of the textile material.
  • the polishing body according to the invention has a long service life and nevertheless nestles surprisingly closely even on very complicated surfaces.
  • the workpiece plunges deep into the polishing body, so that the processing practically does not differ from that with unimpregnated polishing bodies.
  • such impregnating agents can also be used in the processing of complicatedly shaped parts which previously could only be used on smooth surfaces with total impregnation, and in some cases also led to impregnations which are too hard for every polishing operation.
  • the design according to the invention makes it possible to use impregnating agents which cannot be used for polishing bodies by the conventional impregnating methods.
  • polishing bodies according to the invention Examples of polishing bodies according to the invention and the formation of the impregnation can be seen in FIGS. 1 to 17 of the drawing.
  • 1 and 2 show samples of fabrics made of textile raw materials with a dot-patterned impregnation, which can rest on the fabric as well as penetrate into the depth of the fabric layer.
  • 3 and 4 show a further possibility of impregnation in the form of a cross pattern.
  • 5 and 6 show two further options for raster impregnation in the form of straight and crossed lines. It should be noted in this regard that such grids also in wavy lines or other, e.g. Circles, can run.
  • FIGS. 7 and 8 show schematic sisal fabrics with impregnations, such as correspond approximately to the impregnations according to FIGS. 1 to 4.
  • 10 shows the impregnation applied to both sides of a fabric web, the impregnation grid being staggered.
  • 11 shows an impregnation applied to one side of a textile web.
  • FIGS. 12 and 13 show cords impregnated at points, which in the case of FIG. 12 are braided and in the case of FIG. 13 are twisted.
  • the lower part of FIGS. 12 and 13 is intended to clarify that it is not only possible according to the invention to impregnate the finished cord, but also to impregnate the individual threads before the cord is formed.
  • FIGS. 14 and 17 show exemplary embodiments of polishing bodies according to the invention, produced from the textile material according to some of FIGS. 1 to 13.
  • FIG. 14 shows a polishing ring folded from cloth webs, which can be used as such or assembled to form rollers.
  • polishing ring which can either be constructed only from pre-impregnated sisal layers or layered from sisal and cloth layers.
  • the individual layers can be folded, rolled, or preformed in whole or in part and folded together to form a ring. Quilting along concentric lines can also be carried out subsequently.
  • FIG. 16 shows a lamellar arrangement of the pre-impregnated textile webs
  • FIG. 17 illustrates the structure of a brush made of pre-impregnated cords according to the invention.
  • Fabrics made of cotton, sisal, jute, wool or other textile raw materials with a wide variety of thread positions, basis weights, yarn numbers, staple lengths of the individual fibers, etc. can be used as basic textile materials for the polishing body according to the invention.
  • Mixed fabrics are also possible; also those made of or using synthetic fibers. This also applies to the impregnated braided or twisted cords.
  • random-fiber nonwovens from the above. basic textile materials possible.
  • thermosets such as phenol, cresol, furfural, urea, melamine, etc.
  • Resins thermoplastics such as PVC, PVA, PVAc; PVB, polyamides, polycarbonate and others, elastomers such as polyurethanes, ABS, PPE, Thiokol and others, as well as natural resins such as shellac, bitumen and tree resins, and finally also inorganic binders such as water glass and others.
  • Abrasive and polishing particles can be added to the above-mentioned impregnating agents in order to support the polishing work. These include fine abrasive grits, polished red, polished green, cerium oxide, polished clay and others.
  • the impregnating agents also contain additives from polishing aids.
  • polishing aids are particularly lipophilic substances which increase the paste-like properties and thus improve the utilization of the polishing pastes, and also those substances which intervene directly in the polishing process, for example small hollow spheres made of organic material which are filled with grinding paste. It has proven to be particularly useful for high-gloss polishes, for example cotton fabric sheets with punctiform grid impregnation while still sticky Flock condition in the high-voltage field with short cotton fibers. Other types of fibers are also conceivable here in order to specifically perform certain polishing tasks.
  • a particularly favorable effect with regard to the adaptability of the polishing body to profiles and irregularly shaped workpieces with a high and fast polishing effect is obtained if the grid impregnation is only melted or welded onto the fabric web relatively loosely or, in the case of thermosets, only up to the B- Condition is transferred.
  • the necessary softness and resilience remains in the base of the polishing body, while the impregnating materials in the polishing zone weld or change to the C state due to the heat occurring during the polishing process and thus advantageously support the polishing pressure.
  • control in the opposite direction can also take place in that the polishing body is less flexible in the subsurface and the appropriately selected impregnating agents soften in the area of the polishing zone and the polishing body as a whole is divided and fanned out into its individual layers. This effect occurs particularly when the impregnating agent consists only of a small part of binder and a large part of polishing aids.
