Definitions

  • the present invention relates to a spacer textile with a first cover layer, a second cover layer and in between a spacer thread arrangement.
  • the two cover layers are connected to each other by the spacer thread arrangement.
  • the spacer thread arrangement thus fulfills two functions. First, it defines a certain distance between the two top layers. On the other hand, it is compressible to a certain extent, so that the distance between the two cover layers can be changed at least locally.
  • the invention has for its object to provide a further application for the spacer textile.
  • the drop loops form Velcro loops, i.e. a part of a Velcro fastener or a Velcro connection. It is therefore possible to connect the spacer textile to other elements via the cover layer provided with the ejection loops, for example to provide these elements with a flexible layer, this flexible layer being easily assembled and removed again.
  • the spacer textile is designed as an abrasive carrier. It is therefore possible to arrange an abrasive on one side of the spacer textile and, for example, a grinding disc on the other side of the spacer textile.
  • the sanding plate is usually rigid and unyielding, so that the spacer textile has the advantage of producing a certain degree of flexibility between the abrasive and the sanding plate. Such resilience, for example, smoothes the surface pressure, i.e. Even with surfaces that are not completely flat and to be ground, the protruding areas cannot be overstressed. At least the risk of such an overuse is small.
  • predetermined surface areas of the top layer provided with ejection loops are free of ejection loops. This makes these predetermined surface areas more permeable to air than areas that are provided with ejection loops. This improves the removal of grinding dust.
  • the predetermined surface areas are permeable to grinding dust.
  • the predetermined areas not only allow air to pass through, but also grinding dust.
  • the grinding dust can then enter the interior of the spacer textile or from the interior of the spacer textile wander out so that it does not clog the abrasive layer, or only with a delay.
  • the abrasive can then have a longer service life.
  • the spacing thread arrangement is permeable to grinding dust.
  • the grinding dust can then move further in the spacing thread arrangement, for example from the grinding dust-permeable areas on the side of the abrasive to exit areas on the opposite side of the spacing textile.
  • thread-free areas are provided in the spacer thread arrangement, which form flow channels. These flow channels then form a path with a relatively low resistance for the grinding dust, so that the removal of the grinding dust is further improved.
  • the spacer thread arrangement can have areas with different flexibility.
  • the different flexibility can be used for special grinding tasks.
  • areas of the spacer thread arrangement can be provided with a larger number of spacer threads than other areas, for example. It is also possible to use areas with different spacer threads, for example stiffer and less stiff spacer threads.
  • the spacer thread arrangement forms areas with different distances between the two cover layers.
  • the spacer threads then define different thicknesses of the spacer textile. These different thicknesses can follow one another in the production direction of the spacer textile. However, it is also possible to arrange these different thicknesses next to one another transversely to the direction of production.
  • the spacer thread arrangement forms a contour on at least one cover layer.
  • This contour can, for example, be smooth, for example form a continuous increase or decrease in thickness.
  • the contour has a curved surface.
  • the curved surface can form the surface of part of a spherical cap, for example. This is an advantage for some grinding tasks.
  • the first cover layer and the second cover layer are preferably designed as knitted fabrics, the release loops being designed as pile loops of the knitted fabrics.
  • the spacer textile is therefore a knitted spacer.
  • the dropping loops can then be produced at the same time as the cover layers are being produced, which considerably simplifies production. For example, a jacquard system in a warp knitting machine can be used to manufacture pile loops.
  • one cover layer forms an abrasive attachment Velcro layer and the other cover layer forms an abrasive plate attachment Velcro layer.
  • the spacer textile then forms part of a multi-layer system in which the spacer textile is first applied to a sanding plate and then a loop provided with abrasive, abbreviated to a grinding wheel, is applied to the spacer textile.
  • one cover layer is provided with an abrasive and the other cover layer forms a hook-and-loop fastener layer.
  • the spacer textile is coated directly with the abrasive and can be attached to the sanding plate with its other side.
  • At least some of the ejection loops are designed to be electrically conductive. This makes it possible to dissipate electrostatic energy, which is formed in some cases during grinding, directly via the spacer textile, so that higher electrical charges can be avoided.
  • the spacer thread arrangement has spacer threads 5 which are arranged between the first cover layer 2 and the second cover layer 3.
  • the spacer threads 5 can have an inclination to the two cover layers 2, 3. However, they can also be directed (not shown) essentially perpendicular to the cover layers.
  • the spacer threads 5 can also have different directions between the cover layers 2, 3.
  • At least one of the cover layers in this case the upper cover layer (based on the representation of the Fig. 2 ), is provided with discharge loops 6.
  • the spacer textile 1 is designed in the present case as a spacer fabric, in which the release loops 6 are designed as pile loops.
  • the dropping loops 6 thus form a Velcro loop, that is to say part of a Velcro fastener.
  • the ejection loops are intended to interact with so-called hook bands or elements, that is to say bands or elements which are provided with relatively small barbs, which hook together with the ejection loops and thus result in a firm connection.
  • Throw loops can be produced in a warp knitting machine with the help of jacquard bars, as is known, for example, in the manufacture of terry cloth applications.
  • the spacer textile 1 is designed as an abrasive carrier.
  • the spacer textile 1 has an abrasive 7 on the outside of its lower cover layer 3, which consists, for example, of a large number of abrasive grains or an abrasive granulate which is fastened to the lower cover layer 3, for example by gluing.
  • predetermined surface areas 8 of the upper cover layer 2 are free of ejection loops 6. These predetermined surface areas are on the one hand more permeable to air than the areas provided with the ejection loops 6. On the other hand, they are also permeable to grinding dust.
  • the lower cover layer 3 provided with abrasive 7 is also permeable to air and grinding dust.
  • the spacer thread arrangement is also permeable to grinding dust.
  • the spacer threads 5 are at a corresponding distance from one another.
  • thread-free areas 9 are provided in the spacer thread arrangement, which form flow channels.
  • the thread-free areas 9 can agree with the predetermined surface areas 8, which are free of ejection loops.
  • the flow channels 9 are shown exaggeratedly large here.
  • the elasticity of the spacer textile should not be significantly influenced by the flow channels 9.
  • the spacer thread arrangement has areas with different flexibility. In this way, different grinding results can be achieved on the side provided with the abrasive 7 even if the surface pressure on the opposite side is constant. This is desirable for some grinding tasks.
  • the different flexibility can be brought about by choosing the density of the spacer threads 5 differently. With a lower density of the spacer threads, the resilience is greater than with a higher density of the spacer threads.
  • the different compliances can also be brought about by using different spacer threads 5, for example thicker spacer threads and thinner spacer threads, the deformability of which differs.
  • the spacer thread arrangement 4 forms different distances between the two cover layers 2, 3.
  • the two cover layers 2, 3 then do not run parallel to one another over the entire extent, but can be one of have a different shape on one level.
  • at least one of the cover layers 2, 3 can be contoured, that is, form a contour.
  • the contour can have a curved surface, for example.
  • the curved surface can, for example, be the surface of part of a spherical cap.
  • the arrangement of the discharge loops 6 can cooperate with a grinding plate 10 which has on its side facing the spacer textile 1 a series of barbs 11 which can be hooked onto the discharge loops 6.
  • the spacer textile 1 in turn is then attached to the abrasive medium plate 10, the release loops 6 with the barbs 11 forming the desired Velcro connection.
  • the abrasive carrier expediently has a flat perforation.
  • the spacer textile can also be used in a multi-layer system in which the abrasive is not applied directly to the spacer textile 1, but to a separate abrasive carrier, which in turn is connected to the spacer textile 1 via a Velcro connection.
  • the lower cover layer 3 would also have an arrangement of ejection loops 6.
  • the spacing thread arrangement compensates for unevenness with its flexibility, which has a positive effect on the grinding result.
  • the air-permeable pattern of the discharge loops 6 enables the grinding dust to be extracted.
  • the discharge loops 6 can be made of the same material as the cover layers 2, 3. However, it is also possible to use other materials, for example PES, PA, PP, PE or special materials such as metal wires or yarns provided with metal. In the latter case, at least some of the ejection loops are designed to be electrically conductive, so that electrical charges that can possibly form during grinding can be discharged.
  • a double-warp warp knitting machine can be used to produce the spacer textile 1, in which the yarn-guiding laying rail for the ejection loops 6 is controlled by jacquard in order to achieve a targeted displacement, or alternatively a basic laying bar can be used in order to achieve a full-surface ejection loop. This can be used to define the locations at which the drop loops should be created.
  • thread-free areas 9 are provided, which form the flow channels. These areas can also be defined, for example, to bend the spacer textile.
