Definitions

  • the invention concerns an end part for grinding and polishing machines, and which consists of a Velcro hooks having support disk, the abrasive on one side and a fabric for engagement of the velcro hook on the other side having n work disk.
  • Devices of the generic type are known.
  • the holding means of the adhesive closure arranged on the drive disk i.e. so the actual checkmark disc is glued on.
  • the checkmark disc is heated in such a way that the adhesive between the actual drive disc and the checkmark disc is released, making the overall device unusable. So far it was only possible to work up to a working temperature of 130 °. Intermediate rest periods, which led to the drive disk cooling down, were necessary if the tool was not to be rendered unusable.
  • the Velcro hooks are made in one piece with the material of the supporting disk and, on the other hand, the abrasive is applied directly to the fabric layer of the Velcro fastener sealed with a suitable finish using a synthetic resin binder or glue.
  • the support disk with the hook and loop hook can advantageously be made of polyurethane, and the synthetic resin binder of the work disk can be a phenolic resin.
  • the finish on the fabric is applied under the influence of pressure and heat.
  • the fabric can advantageously consist of plastic threads, but for better heat resistance, the sole use or mixture of carbon fibers, glass fibers, asbestos fibers or steel threads is also possible.
  • the fabric used can advantageously be a velor, but it is also possible to use a loop pile or filament or a fabric of another weave. Non-woven nonwovens can also be used, as long as it is ensured with them, as with the other fabrics, that the hooks of the supporting disc can be held sufficiently firmly.
  • FIG. 1 shows in perspective a support plate with a shaft connection, on which a working plate can be placed.
  • the support disk 1 is shown in perspective, which consists of polyurethane and one Carries shaft connection 3 for connection to a work tool. It is cast and integrally molded on the body of the support plate 1 Velcro hook 4 during the casting process, which produce the Velcro connection with the working disc 2 drawn at a certain distance for clarification.
  • the working disc 2 consists of a suitable fabric, as already mentioned above, and has been so extensively finished before the synthetic resin bonding layer for the abrasive is applied that the synthetic resin can be applied in liquid form without passing through the fabric layer 5.
  • the finishing can be done under the influence of pressure and heat (calendering) and a suitable binding agent can be applied in this context.
  • the finish also greatly increases the tensile strength of the fabric 5 used, so that the necessary secure connection between the individual Velcro hooks 4 and the fabric threads or loops of the fabric 5 is obtained.
  • the synthetic resin binder for the abrasive grains 6 can be a phenolic resin, but any other suitable binder can also be used.
  • the abrasive grains can also be glued or glued.
  • the abrasive layer can also consist of an abrasive fleece or corundum velor can be glued on.
  • the working disk according to the invention is produced from a velor fabric.
  • This fabric is a loop pile or fleece fabric, with sufficient strength being achieved via the high density of, for example, 250 g / m 2 .
  • care must be taken to ensure that sufficient stretching strength is set, also in the longitudinal direction of the fabric.
  • the treatment with a finish to be treated below enables this stretch resistance, in particular to the small extent required.
  • the fabric is treated with a finish, e.g. Acrylic resins are treated so that one side is not glued to the loops or loops required to produce the hook-and-loop connection, but is tied on the working medium side in such a way that the plastic binder to be applied for the abrasive can make a sufficient connection or interlocking with the fabric.
  • the surface is closed to such an extent that the plastic binder can be applied to the fabric and does not penetrate it so far that the loops or loops would be filled and the Velcro connection would no longer be possible or would no longer be possible to a sufficient extent.
  • the finish can be applied in a known manner under pressure and heat (calendering), which increases the strength of the weaving points.
  • the application is made possible of the binder for the abrasive (for example, Ph enolharz) by the previous application of the finish and improved.
  • the finish on the one hand strengthens the fabric and the corresponding tensile strength is set, on the other hand the connection of the plastic binding agent with the fabric is improved and excessive penetration of the fabric is avoided, which would reduce the adhesion of the Velcro hooks.
