Definitions

  • skis more especially cross-country skis, besides possessing smooth running properties, must also be designed so as to prevent backsliding during pushing motions or when climbing.
  • the inventor has arrived at such a solution by a really revolutionary procedure involving utilization of a mixture of already known and used acetal resins, where the individual resins possess good anti-friction properties although they also exhibit controlled, slip on damp surfaces, that is, they combine smooth running with anti-back sliding properties as is required.
  • the running surface in accordance with the invention is characterized above all in that said acetal resin mixture is bonded to a fabric backing preferably of glass fibre fabric; this fabric backing is, in turn, suitable for fixing with adhesive to either the whole or part of the underside of the ski.
  • the running surface is also characterized in that the acetal resin of which it is made, is preferably formed by mixing a first acetal resin modified by addition of a fluorocarbon resin, to a second acetal resin modified by addition of molybdenum.
  • the running surface is characterized in that the first acetal resin of the two resins making up the mixture is preferably modified by addition of polytetrafluoroethylene hitherto normally used for injection moulding purposes and possessing special anti-friction properties; the second acetal resin of the two resins making up the mixture is preferably modified by addition of molybdenum and is of type hitherto normally used in extrusion, likewise possessing anti-friction properties as in the case of the first resin, that is, different properties from those required of a running surface.
  • the running surface in accordance with the invention is characterized in that the resin mixture, which is the most important part of the running surface, that is, the part in contact with the snow preferably consists of 30 to 35% of acetal resin modified by addition of molybdenum and of 65 to 70% of the resin modified by addition of polytetrafluoroethylene.
  • the running surface in accordance with the invention is characterized in that the resin mixture forming the most important part of the ski running surface can be bonded by heat and mechanical means to a fabric backing, preferably of glass fibre fabric; bonding consists of heating a surface of the resin mixture to a temperature of 200°C to 215 0 C thereby softening it and applying a pressure of 2 kg/sq.cm to permit subsequent joining to the fabric backing; this fabric backing is, in turn, fixed by means of suitable adhesive to the ski or to part of it.
  • fig. 1 is a perspective view of part of the resin mixture bonded to part of the fabric backing
  • fig. 2 is an analogous perspective view of a more complex solution in which said components are bonded to another layer of wood, metal or plastic, and the bonded assembly is fixed via an intermediate joining layer to another backing layer or directly to the ski.
  • Figures 3a, 3b, and 3c show three skis to whose underside is fixed the running surface according to the invention in differently arranged and extensive zones.
  • Figure 4 is an exploded view of the various members, that is, members detached from one another, in which the ski has a bottom running surface formed as shown in fig. 3a.
  • the running surface in question consists of a mixture of acetal resins 10 which can be bonded to a fabric backing 11, preferably of glass fibre fabric, by heat and mechanical means as stated previously.
  • the laminate obtained by hot bonding of acetal resins 1 0 to fabric 11 is designated by the number 12 in the figures.
  • This laminate can be cut to desired size thereby obtaining various elements 12 which can be joined to other already familar running surfaces 14 of wood, metal or plastic (fig. 2).
  • both members can be joined with a suitable glue or adhesive 15 to another backing layer or to the actual ski 16.
  • Fig. 3a illustrates a solution in which a central layer of the running surface in accordance with the invention is bonded to end layers of running surfaces made of already known material 14;
  • fig. 3b instead, shows just two centrally positioned parallel longitudinal strips of running surface 12 in accordance with the invention, while in fig. 3c, two end sections of the running surface 12, in accordance with the invention are applied to the ski besides the two central longitudinal. strips.
  • the acetal resins can be with random or preferred orientation or with orientated molecules.
  • the fabric backing it has been said that it is preferably of glass fibre fabric, but it is obvious that these fibres can be of any other material providing that it is easy to adher such material to the ski and provided that the material can be efficiently bonded by heat and mechanical means to the acetal resin mixture in accordance with the invention.
  • Bonding of the acetal resin mixture to the backing fabric can be carried out with aid of a press, or by a series of hot pressure rolls or pads; the required heat can be gained from that contained in the product itself when emerging from the extruding head after calendering.
