Definitions

  • the present invention relates to grinding and polishing belts and in particular to belts of this type which can be closed again in a simple manner after being severed.
  • Grinding or polishing belts are used in the form of endless belts closed to form rings for grinding or polishing round tubes, round timbers or the like.
  • the grinding belt is pushed on the one hand laterally onto the workpiece to be machined and, on the other hand, placed around a grinding belt drive roller of a belt grinding device.
  • the sanding belt In order to be able to machine closed constructions in which it is impossible to slide the sanding belt sideways on, the sanding belt must be cut through, the object to be processed must be folded over and then closed again to form a ring. So far, the abrasive belt has been reconnected by pasting the band folded together into a ring over its entire length with a special band. Although this solution is very effective and reliable, it is also time-consuming. Significant amounts of fabric tape are also required.
  • the invention in its first aspect, relates to endless belts, that is to say those which are closed to form a ring.
  • Such tapes are generally known. They consist of a band-shaped base which can consist, for example, of a fabric made of natural or synthetic fibers. Cotton or polyester tape can be mentioned by way of example.
  • One side of the belt is coated with the grinding or polishing agent. Examples of such abrasives and polishing agents are abrasive grains of different grain sizes, non-woven fabrics or felt.
  • the present invention is not limited to specific grinding or polishing belts, but is basically suitable for all types of these belts.
  • the invention will now be described with reference to grinding belts, without being limited to these. The statements apply correspondingly to other types of tapes.
  • the abrasive belt is coated on its rear side, which is not coated with abrasive, over at least a portion of its circumference with an adhesive which, if necessary, is covered with a removable protective film.
  • This section preferably has a length of at least 3 to 4 cm, for example a length of 3 to 10 cm and in particular of 4 to 6 cm.
  • the adhesive coating is expediently applied over the entire width of the tape.
  • Preferably only a partial section per endless belt is coated with adhesive, but it is also possible to provide two or more sections distributed over the circumference of the grinding belt with adhesive.
  • the reclosable connection is particularly easy to manufacture and handle by virtue of the fact that the adhesive coating is applied to the back of the support usually used for the original closure, following the original joint of the tape.
  • sections of the sanding belt coated with adhesive are expediently marked in color, for example by coloring the sanding belt base.
  • the middle of each section is particularly preferably additionally marked by a cross line or the like.
  • the grinding belt is severed in the region of the partial section provided with adhesive.
  • the separation is particularly preferably carried out in the middle part of the section, since in this case the best durability is achieved after re-bonding.
  • the separated endless belt is now placed around the pipe part, put together again at the severed edges and closed again by applying an adhesive pad, which can also be referred to as an adhesive patch.
  • the adhesive pad essentially has the size of the partial section coated with adhesive. The application of the adhesive pad is thus considerably easier than completely covering the endless tape with fabric tape.
  • the adhesive pad consists of a carrier material which is coated on at least one side with adhesive.
  • the carrier material can be, for example, a fabric layer made of natural or synthetic fibers, e.g. B. cotton or polyester fabric. Films or films made of polymeric material are also suitable.
  • Suitable adhesives for the adhesive pad are those which are compatible with the backing material and which provide a firm but sufficiently flexible connection with the adhesive applied to the sanding belt.
  • the adhesive connection should be strong enough to withstand the loads acting during the grinding process, but at the same time be able to adapt to the deformations occurring during grinding.
  • Adhesive connections of this type can be produced, for example, with suitable two- or multi-component adhesive systems.
  • One component is applied to the partial sections of the sanding belt, the other to the adhesive pad. If necessary, these components must be activated by applying solvent to the contact points, by pressure, heat or in some other way. The exact procedure is known to the person skilled in the art and therefore need not be explained in more detail here.
  • the systems epoxy resin / acid anhydride, epoxy resin / polyamine, polyisocyanate / polyol, or butadiene / styrene / polyisocanate, butadiene / acrylonitrile / styrene / polyisocyanate can be mentioned as examples of multi-component adhesive systems.
  • Resin / hardener systems based on epoxides, polyesters, (meth) acrylates and polyurethanes are also suitable.
  • the adhesive connection can also be produced using so-called contact adhesives, in which the adhesive surfaces for producing the adhesive contact are pressed together under pressure.
  • Adhesive systems based on polyurethane or polychloroprene can be mentioned here as examples.
  • hot-seal adhesives which can be activated by heat, for example those based on polychlorobutadiene, are particularly suitable.
  • the heated adhesive surfaces are pressed together under pressure.
  • pressure sensitive adhesives in which the adhesive surfaces are joined together under pressure, are also suitable for the purposes of the present invention.
  • Acrylates and rubbers can be mentioned by way of example for this type of adhesive.
  • the present invention is therefore not limited to specific adhesives, as long as the prerequisite is met that the adhesive bond between the sanding belt and the adhesive pad is strong enough to withstand the loads during the sanding process and is flexible enough to adapt to the Sufficiently adapt the grinding belt to the deformations.
  • the adhesive pad can be coated on both sides.
  • the endless belt can thus be cut again at the old joint and closed again by putting on another support.
  • the sides of the support coated with adhesive can be covered with a removable protective film.
  • the protective film can be designed as a tube or have folded ends.
  • the endless belt according to the invention can have not only one but several coated sections, on which the endless belt can be opened one after the other and closed again with one-sided coated adhesive pads.
  • FIG. 1 schematically shows an inventive grinding belt
  • FIG. 2 shows the sanding belt according to FIG. 1 in the separated state
  • FIG. 1 shows an abrasive belt 1 according to the invention, in which only a partial section 2 is coated with adhesive 3 on both sides of the original joint 7.
  • a pad 8 for connecting the two ends of the tape is glued thereon, which is also provided with adhesive on its rear side.
  • the adhesive on the back is covered with a removable protective film 9.
  • the sanding belt is first separated in the area of the adhesive-coated section 1, preferably in the middle thereof or at the original joint 7 (FIG. 2).
  • the cut sanding belt is then placed around the object to be processed and then used again. closed.
  • the two severed ends of the band are put together at the separation points 4, 4 ', as can be seen in FIG. 3.
  • an adhesive pad 5 coated with the same or another compatible adhesive is placed on the back of the pad 8a, 8b coated with adhesive, optionally activated, for example by heat, and on the grinding belt pressed down.
  • the adhesive pad 5 is coated on both sides with adhesive and is also covered with a protective film 6 on the side not connected to the grinding belt.
  • both sides of the support coated on both sides are coated with different adhesive components, the rear layer of the adhesive support having the same adhesive component that was coated on the sanding belt.
  • at least one side of the support is expediently different in color from the other support side.
  • the length of the sanding belt may be varied. This is also very easily possible with the grinding belt according to the invention. For example, two sanding belts can be severed in the area of their coated partial sections. If the coated end sections of one band are now put together with the end sections of the other band and, as described above, connected with an adhesive pad, an endless band with double circumference is produced. It is also possible to cut sections from endless belts with several coated sections and to insert these sections into another belt. The same applies to sections from the meter goods described below.
  • the present invention provides not only endless belts, but also abrasive tape by the meter coated with adhesives.
  • a continuous sanding belt which is not closed to the ring and which has, at certain intervals, adhesive-coated partial sections (2) on the rear side not provided with abrasive, as is shown schematically in FIG.
  • a piece of suitable length is cut off from the piece goods as required, the sanding belt always being cut in the area of the adhesive sections.
  • the grinding belt is preferably cut approximately in the middle of the sections 2.
  • the assembly into an endless belt of suitable length is carried out in the manner described above, in that the end pieces of the belt provided with adhesive coating are placed next to one another and connected with an adhesive pad of the correct size.
  • a further possibility is to coat the entire rear side of the meter sanding belt with adhesive.
  • the sanding belt obtained in this way can be used on any one "", " ⁇ ⁇ , PCT / EP96 / 05342
