Definitions

  • the invention relates to a device for reducing the Roughness and the abrasion of layered tapes by means of a rotating polishing device with structural peripheral surface.
  • a layer with a binder e.g. from a softer Plastic is made of PVC.
  • Such layers are used in abrasion-sensitive devices operated, these tapes in contact with surfaces of stationary or moving parts of the device can occur Deposits or deposits of abrasion malfunctions occur.
  • the object of the invention is thus such abrasion remove from layer tapes for use in the above characterized devices are determined.
  • the object is achieved with a device for Reduce roughness and abrasion of laminated tapes by means of a rotating polishing element with a structural peripheral surface, by means of a provided on the circumference of the polishing member thread-like structure.
  • the polishing member is a cylinder, whose height corresponds at least to the width of the layer tape and in particular is twice as large.
  • the circumferential structure of the cylinder can expediently consist essentially of coaxially arranged grooves exist, which are also thread-like Can have shapes and also with a minimum increase of 0.16 mm can be arranged.
  • polishing member also axially arranged grooves on the cylinder circumference.
  • the axial grooves can have a V-shape, in particular a Includes angles of 112 °, but they can also have a sawtooth shape, in particular an angle of 63 °.
  • the number of coaxial grooves can be between about 1 and 20 and should be around 10 for best results.
  • the coaxial grooves can have a substantially V-shape and the webs in between can have a flank width of 0.1 mm on the Have cylinder peripheral surface.
  • the material of the cylinder circumference expediently consists of hardened Stole. However, it can also be advantageously made of oxide ceramic or a hard metal alloy.
  • the material of the cylinder circumference should have a hardness of at least 60 Rockwell.
  • embodiments of the device according to the invention are shown and described below with reference to this.
  • a polishing member is shown in Figures 1 and 2 as a polishing cylinder 5 and 5A with a central bore 6 or 6A for receiving a not shown axis of a rotary organ.
  • either coaxial grooves 8 in the form of a ring or as coaxial, thread-like, helically arranged grooves are provided on the circumference 7 of the polishing cylinder 5, 5A.
  • the cylinder 5 has the diameter 2r, the cylinder 5A the diameter 2R up to the outer circumferential surface, in which the tips of the webs 9 also lie between the grooves 8.
  • the grooves 8 are applied to the cylinder circumference 7, for example in a known manner, by turning or grinding.
  • the grooves 8 can have a V-shape, for example with an angle ⁇ of approximately 40 °.
  • other groove shapes can also be used.
  • the tips of the webs 9 are ground off with suitable grinding devices after the grooves 8 have been produced, so that they still have a defined one Flank width "of about 0.1 mm and thus also have two polishing edges instead of just one.
  • axial grooves 10 can also be provided from the circumference of the cylinder 5 or 5A.
  • the groove shapes are as follows: V-shape for grooves 10A with an angle ⁇ of approximately 112 °, sawtooth shape for grooves 10B with an angle ⁇ of approximately 63 ° and rectangular shape for grooves 10C with an angle ⁇ of approximately 3.6 °.
  • Other groove shapes within the meaning of the invention are also suitable for detaching and absorbing the abrasion from the layer tape.
  • the grooves 10 are produced by sawing, milling, grinding or also by spark erosion processes or EDM (Electrical Discharge Milling) processes.
  • the surface of the layered tape is in a thickness range of a few molecular layers so strongly heated that the roughness tips melt and in doughy condition in the valleys are smeared in, the surface being smooth and becomes shiny.
  • This enamel layer is referred to as the "Beilby layer”. It is essential that no material is obtained by polishing is removed, neither in the form of chips or other Particles, in another form. This will surprisingly an occurrence and deposition of abrasion with its above-mentioned Disadvantages consciously avoidable.
  • the abrasion of layer tapes could be increased by a factor of 10 using the device according to the invention can be reduced with a small device, Manufacturing and maintenance expenses.
  • a polisher to reduce roughness and Abrasion from layered strips consists of a cylinder with coaxial Grooves or grooves of various shapes, which are advantageously thread-like are. Axial grooves can also be provided be.
