Definitions

  • the invention relates to a ski manufacturing process and a ski that according to. this process is made. While skis were previously made from several layers of wood, today they consist of layers of very different materials, mostly plastic, metal and possibly also wood.
  • the object is achieved by the features of claim 1.
  • the method communicated in claim 1 essentially consists of two process steps.
  • a ski upper part is manufactured in a form provided for this purpose, which is then connected in a second process step to a ski lower part of the common type.
  • the ski top manufactured in the molding process consists e.g. consisting of a cover layer, a core and laterally inserted side damper layers.
  • the cover layer is shaped during the molding process in such a way that it forms flange-like edges which rest on the lower part of the ski during assembly, so that in the second process step, connecting the lower part of the ski to the upper part of the ski, an additional connection of the two parts via the flange-like edges is possible is.
  • the upper part of the ski can also be prefabricated without a core and laterally inserted side damper layers.
  • the individually prefabricated upper part of the ski and lower part of the ski can be connected in an advantageous manner by foaming the free core area of the upper part of the ski, for example with polyurethane or a similar material.
  • the prefabricated upper part of the ski is connected to the prefabricated lower part of the ski and the enclosed empty space formed thereby is foamed to form the core of the ski.
  • the flange-like edges are formed in a constant width and are brought to their final shape only after removal from the mold, it being possible for the excess to be milled away, for example.
  • This has the advantage that for skis that have a different profile in plan view, that is, each with their own shapes for their manufacture differently designed edge areas would have to be provided, only one shape with a constant straight edge must be present.
  • the upper part of the ski is then adapted to the respective shape of the lower part of the ski.
  • This lower part of the ski can be of any design. For example, it consists of a polyethylene tread bordered by steel edges, over which a lower belt is arranged.
  • a decorative layer is placed in the mold box of the mold below the cover layer which has a supporting function and which, of course, lies on the surface of the upper part after the upper part has been removed from the mold box.
  • the decorative layer can either cover only the surface of the upper part of the ski or the surface as well as the side edges of the upper part of the ski.
  • the process step of ski top shaping can be designed in an advantageous manner in that the cover layer consists of one or more layers which are flexible at ambient pressure and ambient temperature before the final molding process. With these flexible layers, the shape can be designed before the core and side damper layers are inserted. Covering layers made of an epoxy prepreg or a polyester prepreg of the customary commercial form are suitable for this procedure.
  • the upper part of the ski is connected to a stable molded body at suitable temperature and pressure by polymerization.
  • An alternative embodiment of the method according to the invention consists in the fact that the cover layer consists of a thermoplastic shell inserted into the mold.
  • the decorative layer can also be designed as a thermoplastic layer or thermoplastic shell.
  • a damper layer made of the most entropy-elastic material for example an elastomer
  • a ski can be produced in a simple manner which has a upper part of the ski which is trapezoidal in cross-section, the side surfaces being inclined at a constant angle.
  • Fig. 1 the molding step of the ski top 10 is shown in a form consisting of a mold box 18 and a mold cover 20.
  • a decorative layer 24 is placed on the bottom of the molding box 18.
  • This decorative layer 24 is flexible at ambient pressure and ambient temperature. It consists of an epoxy prepreg or alternatively, for example, of a polyester prepreg.
  • a cover layer 12 is placed on this decorative layer, which is also flexible at ambient pressure and temperature.
  • This cover layer is also laid along the side walls which are inclined at an angle ⁇ with respect to the vertical.
  • the still flexible cover layer 12 is then bent in such a way that it forms a flange-shaped edge 22. Since the cover layer 12 is a load-bearing layer, it is reinforced. For this purpose, fiber-proven mats or carbon inserts are used.
  • a core 14 is placed on this cover layer, which can consist of any ski building material customary for cores. For example, a foamed plastic. Between the core 14 and the laterally raised cover layer 12, triangular side damper layers 16 are inserted into the mold in cross section. These side damper layers 16 are, for example Made of an elastomer and serve to protect the core from the side.
  • the mold is closed with the mold cover 20 and, under suitable pressure and at a suitable temperature, the individual layers are polymerized with one another, so that a dimensionally stable ski upper part 10 is produced.
  • the molding box 18 is shaped according to the thickness distribution over the length of the upper part of the ski.
  • the core 14 of the upper part 10 of the ski is made thicker from the longitudinal center of the ski, i.e. exactly in the area in which the ski binding will be arranged later.
  • the thickness of the core decreases towards the center of the ski and towards the ski shovel, as shown in FIG. 2.
  • the upper ski part prepared in this way is applied to a lower ski part of a conventional type (not shown) and glued to it in the usual way.
  • the upper ski part 10 can be connected to the lower ski part, not shown, along the flange 22 using conventional fastening means.
  • the lower part of the ski can consist, for example, of a polyethylene tread which is bordered by means of steel edges, a lower flange usually being arranged above the polyethylene tread. But it can also be any lower ski with a ski upper 10, which according to. the previously described sequence of processes was connected.
  • a ski upper part 10 is also shown in the mold 18, 20 during the molding process. According to this exemplary embodiment, however, a further substep is added to the method for producing the ski during the method step of assembling the upper ski part 10.
  • the bond area i.e. in the area on which the bond is later applied, an entropy-elastic damper layer as possible. This advantageously consists of an elastomer.
  • the length of the damping element 26 is designated by L in FIG. 4. L can typically vary in a range of 500-700 mm. The length of the area L depends on on the total length of the ski.
  • the mold cover 20 can have a corresponding bulge (not shown in the figures).
  • This modified ski upper part is then connected to a lower ski part, at the same time the empty core area is foamed, for example with polyurethane or a similar material.
