Abstract

Fremgangsmåte for fremstilling av en hul ski og hul ski fremstilt på denne måt- en. I de kjente hule ski er utgangsmaterialet plassert slik i en pressform, at det omgir et elastisk luftkammer, som blir satt under trykk, hvoretter så materialet blir herdet. Med den fremgangsmåten som angår oppfinnel- sen skal det laget en hul ski, som har liten vekt med stor styrke. Til dette blir luftkamrene dannet av to avsnitt av en dobbeltslange, som ligger ved siden av hverandre i den hule skis lengderet- ning, hvor det i hvert avsnitt av dob- beltslangen på en lufttett tynnvegget innerslange av et kunststoff som kan utvide seg blir trædd på en ytterslange som er laget av en fiberduk og etter å ha trukket opp en kunstharpiks blåses opp med innerslangen og på glideflate- delen og på det som danner yttersjiktet av hullegemet, også gjennomtrukket med kunstharpiks, hvor materialet er en fiberduk og i det midterste området av hullegemet blir presset på ytterslangene til det andre avsnittet av dobbeltslan- gen og derved blir utformet som en ver- tikal kant som strekker seg i den hule skis lengderetning, hvorved delene ved herdingen blir forbundet fast med hver- andre og danner den hule skis kraftover- førende forbindelse.Process for the preparation of a hollow ski and hollow skis prepared in this way. In the known hollow skis, the starting material is placed in such a mold that it surrounds an elastic air chamber, which is pressurized, after which the material is cured. In accordance with the method of the invention, a hollow ski, which has a small weight of high strength, is to be made. To this end, the air chambers are formed by two sections of a double hose, which are adjacent to each other in the longitudinal direction of the hollow ski, where in each section of the double hose on an airtight thin-walled inner tube of a plastic that can expand can be stepped on an outer hose made of a nonwoven fabric and after pulling up an artificial resin is inflated with the inner hose and on the sliding surface portion and on that which forms the outer layer of the hollow body, also impregnated with synthetic resin, the material being a nonwoven fabric and in the middle region of the the hollow body is pressed onto the outer tubes of the second section of the double tube and thereby is formed as a vertical edge extending in the longitudinal direction of the hollow ski, whereby the parts of the curing are joined together to form the hollow ski's power transmission. leading connection.
