Definitions

  • the invention relates to a packaging unit of flat Abrasives and a method for packaging flat Abrasives according to the preamble of the independent claims and the use of a hot melt adhesive or of a dispersion adhesive in a packaging unit for flat abrasives.
  • Flat abrasives are used for grinding and polishing a variety of different embodiments are known.
  • the abrasives are, for example offered as ribbons, discs or rectangular sheets. Slices and sheets are often stacked and Sanding belts packed as rolled spirals. The stacks or the spirals are through the packaging or through Packaging aids, e.g. Tapes held together. After first removing the packaging or packaging aids the individual layers of the abrasive no longer held together. Packing in solid and Resealable boxes have this disadvantage not, but leads to an increased consumption of packaging material and to undesirably large amounts of waste.
  • the abrasives are in one package as one Packed in a variety of layers.

In the case of spiral wound sanding belts can be of the desired length the spiral can be detached.
  • each Layer of the abrasives can be wholly or with the adhesive covered in sections. Depending on the shape or thickness of the Abrasives are different arrangements of the adhesive advantageous on the edges.
  • an adhesive on one To use carrier material.
  • the carrier material stabilizes the adhesive layer. This can be especially during the Applying the layer may be beneficial.
  • the roughly rectangular sanding sheets are at least on one side connected. It is particularly advantageous but it is possible to close the sanding sheets together on two sides connect. Both the arrangement of the adhesive layer is conceivable on opposite sides as well two at an angle to each other and touching Pages.
  • the connection on more than one side leads to one and better stability of the stack of abrasives therefore especially with sanding sheets with coarse grain, which are relatively heavy, advantageous.
  • the Adhesive layer advantageously over several, advantageously about three circumferential angular ranges of the disks. It has it turned out that several, over circumferential angle ranges adhesive layers extending from less than 10 ° are particularly advantageous and to the necessary stability to lead.
  • a spiral-wound sanding belt held together.
  • the edges of the sanding belt form two side faces of one Spiral.
  • the individual layers of the sanding belt are through Glue held together on the side surfaces of the spiral.
  • the application of adhesive has proven to be particularly advantageous exposed only in sections of the side surfaces of the spiral.
  • the adhesive can, for example, in one or several running through the center of the spiral Strips are applied. Alternatively, it is conceivable, the adhesive only in certain angular ranges Apply side surfaces.
  • an adhesive in particular a Hot melt adhesive or a dispersion adhesive for releasable Connecting edge sections of a plurality of superimposed ones Layers of a flat abrasive in one Packaging unit used.
  • the use of adhesives to hold pages of books or notepads together is known.
  • Adhesives for packaging abrasives have so far been used not recognized.
  • the packaging unit can be damaged, especially during transport can also be covered with banderoles.
  • top layer of the abrasive with a label replace, for example with a printed rectangle or a printed disc.
  • Figure 1 shows schematically in perspective an arrangement 1 according to the invention from a variety in several layers of 10 superimposed rectangular sanding sheets 2.
  • the sanding sheets 2 have a sanding surface 7 on and are limited by an edge 8.
  • the different Layers 10 of the abrasive 2 are on the edge 8 on one Page 3a by an applied layer 20 of an adhesive held together.
  • An adhesive is advantageous Hot melt adhesive or dispersion adhesive, for example Synthetic resin dispersion based on polyvinyl acetate such as PLANATOL BB Superior from PLANATOL Klebetechnik GmbH.
  • the adhesive can be applied directly as a layer. It but it is also conceivable to glue on a carrier material use (see Figure 9).
  • Figures 2a to 2c show three such possibilities.
  • Figure 2a shows the embodiment of Figure 1 in the Top view.
  • the adhesive layer 20 is on one side 3a applied to the edges 8 of the sanding sheets 2.
  • FIG. 2b shows a top view of an arrangement according to the invention, according to which the individual layers of the sanding sheets 2 on two opposite sides 3a, 3b by an adhesive layer 20 are held together.
  • An arrangement according to FIG. 2b this is particularly the case with coarse-grained or heavy ones Abrasives beneficial.
  • Figure 2c shows a further advantageous embodiment.
  • the Sanding sheets 2 are also on two sides 3a, 3c at the edge 8 connected to each other by an adhesive layer 20.
  • the Pages 3a, 3c according to FIG. 2c are at an angle to one another and touch each other. With such an arrangement a similarly good stability as in Figure 2b achieved.
  • the Removing the sanding sheets 2 is due to the exposed corner 4 easier.
  • Figure 3 shows schematically how an abrasive sheet 2 for use can be removed. Thanks to the detachable connection of the individual Layers 10 of the sanding sheets 2 with one another can Sanding sheet 2 raised and from the rest of the packaging unit 1 be demolished.
  • Figure 4 shows a perspective view of an inventive Arrangement 1, in which round grinding wheels 22 lie one above the other in several layers 10.
  • the grinding wheels 22 are by one applied in a peripheral portion 23a Adhesive layer bonded together.
  • the adhesive layer 20 can be applied over larger circumferential angle ranges ⁇ or can also be applied in several circumferential sections.
  • FIG. 5a shows a top view of arrangement 1 according to FIG 4.
  • the grinding wheels 22 are in a peripheral section 23a, which extends over an angular range ⁇ through the Adhesive layer 20 bonded together.
  • the individual layers 10 as shown schematically in Figure 5b in a larger Circumferential portion 23 are connected together.
  • the circumferential angle range ⁇ , in which the adhesive layer 20 the edge 8 of the grinding wheels is applied is more than 90 °.
  • Adhesive and the removal of individual sealing washers 22 is difficult.
  • FIG. 5c shows a particularly preferred exemplary embodiment, according to which the individual layers 10 of the grinding wheels 22 at its edge 8 in two circumferential sections 23a, 23b an applied layer of adhesive 20 are held together.
