Definitions

  • the invention relates to a method for treating plastic treads from Winter sports equipment, especially skis or snowboards, and a device for Implementation of such a procedure.
  • Skis, snowboards and similar winter sports equipment with gliding surfaces are nowadays practically exclusively with plastic treads, since these apart from the easy manufacture also the best sliding properties among those usually used in the Use of such devices prevailing temperature conditions relative to snow surfaces in various conditions (from powder snow to firn or bare ice) exhibit.
  • prevailing temperature conditions relative to snow surfaces in various conditions from powder snow to firn or bare ice
  • wear or damage Depending on the specific composition of the tread surface, it occurs in the Over time to more or less pronounced wear or damage the treads, which leads to the development of various repair and service procedures Treatment of these treads, with which the treads are sought if possible again in the optimal condition for the gliding properties of the device bring or remove damage.
  • the most common method is grinding the tread (surface of the surface) with a rotating grindstone or a grinding belt running over rollers, whereby the Grinder parallel to the surface to be treated moved in the longitudinal direction over this becomes.
  • the mechanical removal of the outermost surface layer in this way (usually only a few hundredths to tenths of a millimeter are necessary) can remove small bumps and damage to the surface and make it dependent from the used abrasive grain structures are given that wax and similar subsequently applied agents which improve the sliding properties adhere better leave or in the depot-like depressions torn from the abrasive grains to save.
  • such grinding processes are common also used in the manufacture of such winter sports equipment.
  • a disadvantage of these grinding methods is that, owing to the more or less heavy material removal can only be repeated to a limited extent, that deeper wear or damage can not be removed or only with excessive removal and that when grinding out of the tread surface protruding microfibers uncontrollably arise, leading to dandruff formation and deterioration of the sliding properties can lead.
  • Processes are also known from DE 40 13 901 A1 or DE 40 33 235 A1, for example and devices are known which have a macroscopic profiling of ski soles Grooves in the longitudinal and transverse directions allow for optimal climbing and gliding properties to rent. These grooves are made, for example, by Hot stamp the correspondingly heated tread using a stamp in the form of a groove. However, these procedures do not allow the recovery of worn or damaged ones Treads and no advantageous microscopic structuring of the treads.
  • the object of the present invention is to provide a method and an apparatus for type mentioned so that the treads to be treated in view can be brought back to an integrity condition for wear and damage and that they are also in view of the important provision for such winter sports equipment optimal microscopic surface conditions with regard to their surface structuring can be optimized.
  • This object is achieved according to the present invention in a method mentioned type in that the tread to be treated in contact with a brought this overlapping embossing die superficially by briefly heating it heated at least until a plastically deformable state is reached, by embossing under largely the same pressure over the entire tread corresponding to the The surface of the embossing die is deformed and then again by cooling the embossing die is solidified.
  • the inventive device for performing such The method has a surface that can be brought into contact with the surface of the device to be treated.
  • this overlapping embossing die further one on the device facing away from the device to be treated Heating and cooling device arranged on the side of the embossing die, which can be activated as required, as well as largely the same pressure across the entire tread treating device in the direction of the embossing die.
  • a ski to be treated is first checked to see whether There is wear or damage to the tread to a greater extent, which may be the case in advance the application of a corresponding amount or layer thickness of Additional material in the described form on the embossing die and / or the one to be treated Tread required.
  • the ski then comes into contact with the tread to be treated that the tread area to be treated expediently with some lateral protrusion overlapping embossing die brought for the further process relative to Treating tread remains stationary, which is due to the loading device that over the entire tread to be treated exerts largely the same pressure is reached.
  • the embossing die In this state of the ski to be treated, which is preloaded and fixed relative to the embossing die the embossing die is then heated until at least the tread to be treated has reached a plastically deformable state, which changes the surface structure of the Press the embossing die into the running surface or show it negatively on it. Immediately afterwards the embossing die is cooled down again, so that the embossed tread again is solidified.
  • the short-term heating of the embossing die preferably up to at least partial melting of the additional material with at least superficial melting of the tread to be treated, so that a intimate connection of the additional material can take place with the old tread.
  • the surface of the embossing die is then shown on the newly applied layer.
  • the hot stamping described is sufficient for the treatment Tread without additional material.
  • the microstructure obtained Surface is an exact negative image of the surface of the embossing die, which is preferred a ground surface structure on the side facing the tread to be treated having.
  • the micrograph can thus be made, for example, by means of a rotating one Grinding stone of freely selectable grit treated aluminum embossing die (without those mentioned at the outset, which result from the direct grinding of a plastic tread Microfibers) easily and precisely applied to the plastic tread to be treated be what the advantages of ground treads without offers the disadvantages mentioned.
  • the embossing die could, of course, be used other suitable surface structures through appropriate mechanical, chemical, receive electroerosive, or similar treatment, which has a wide variety of influences on the surface structure of the treated tread that is ultimately preserved.
  • the heating and cooling device each have a separate, alternatively adjacent to the embossing die has bringable heating or cooling element.
  • the treatment process can thus proceed very quickly, which both in the production of skis, for example, as well as their service-related treatment is very important.
  • the loading device of the device according to the invention more preferably has Embodiment of the invention one on the tread of the device to be treated arranged on the opposite side of the tubular packing, the interior can be acted upon with pressure medium and the device to be treated on the embossing die suppressed.
  • This tube-like filling body enables a uniform way in the simplest way Pressure of the tread to be treated on the embossing die regardless of Formation of the device to be treated on the side facing away from the embossing die - see above can, for example, in such an embodiment of the device according to the invention Ski to be treated easily held and evenly with the binding attached be pressed.
  • the loading device could of course also for example, consist of individual pneumatic elements or the like, which with accordingly short distance or correspondingly large respective pressing surface also a sufficiently uniform pressing of the surface to be treated on the embossing die can ensure.
  • the heating element can, for example, be of an electrical type or with a flow-through Steam or the like heated plate exist, with the usual tread materials a working temperature of approx. 200 ° C to 300 ° C must be maintained, at which heating the embossing die in a time range of about 30 seconds for the invention Procedure is sufficient.
  • the cooling element can, for example, with a liquid or gaseous coolant can be flowed through and preferably has one Working temperature from about 3 ° C to 10 ° C.
  • the required cooling time for the embossing die in this case is about 40 seconds, whereby it is for different materials or Procedures can also be quite possible, the specified temperatures and Adjust times accordingly.
  • Fig. 1 shows a side view of the entire 2 shows an enlarged section along the line II-II in FIG. 1st
  • the device shown is used to treat plastic treads from Winter sports equipment 1, such as especially of skis or snowboards, and essentially has one with the tread 2 of the device 1, if necessary with prior application of additional plastic material in pasty form or in tape, foil, granulate or powder form (see layer 3 in FIG. 2), which can be brought into contact and covers the tread 2 Embossing die 4, further one on the device 1 to be treated facing away Side of the embossing die 4 arranged heating and cooling device, which can be activated as required 5, as well as a largely identical pressure on the surface to be treated over the entire running surface 2 Device 1 in the direction of the stamping die 4 exerting load device 6.
  • the embossing die 4 and a support plate 7 arranged below the same is - as in particular 1 - the loading device is fixed relative to the base frame 8 of the device 6 is adjustable in height in the direction of arrows 9.
  • the heating and cooling device 5 consists of a separate, alternatively adjacent to the embossing die 4 bringable heating or cooling element 10, 11, which - as can be seen from Fig. 1 - by means of a Carriage 12 and a spindle drive 13 in the longitudinal direction of the device relative to Base frame 8 are slidable.
  • the loading device 6 has one on the tread 2 to be treated arranged on the side facing away from the device 1, tubular filler 14, the Interior can be acted upon with pressure medium in a manner not shown here and the device 1 to be treated presses on the embossing die 4.
  • the embossing die 4 faces on the side facing the tread to be treated a surface structure symbolized in FIG. 2 by a wavy line, preferably ground in on, which in the treatment according to the invention, as in the following again briefly described on the tread 2 to be treated (or possibly on the surface of the applied additional material (layer 3)).
  • the respective device 1 with the one to be treated Surface 2 brought into contact with the embossing die 4, by brief Heating the same - while the carriage 12 is in a position that the heating element 10 positioned below the support plate 7 - superficially at least until it is reached of a plastically deformable state, heated by embossing by means of the whole Tread 2 largely the same pressure corresponding to the surface of the embossing die 4th deformed and then by cooling the embossing die (the carriage 12 in a position that now positions the cooling element 11 below the support plate 7) solidified again.
