PROCESS FOR MAKING A HOLLOW SKI AND HOLLOW SKI MADE THEREBY |
摘要 |
In prior art hollow skis the raw material is arranged in a mould in such a way that it surrounds an elastic air chamber which is pressurised, whereafter the material is cured. The process of the invention is intended to provide a hollow ski of low weight and high rigidity. To this end the air chamber takes the form of two sections of a double hose (6, 7) side-by-side in the longitudinal direction of the ski. In each section of the double chamber a fibre-fabric outer hose (7) is pushed over an airtight, thin-walled and expandable plastic inner chamber (6) and, after impregnation with a synthetic resin, it is inflated through the inner hose and pressed against the running surface and against the fibre-fabric material forming the outer layer of the hollow body which is also impregnated with synthetic resin so that a vertical ridge (8) is formed along the hollow ski. The components are firmly bonded together by curing and form the ridig bond of the hollow ski. |
