Abstract

POSTUPAK ZA IZRADU ŠUPUE SMUČKE I TAKO IZRAĐENA ŠUPLJA SMUČKA od plastične mase ojačane vlaknima, čiji se polazni materijali koji obuhvataju ploču kao i materijal od koga je načinjen spoljni sloj šupljeg tela, stavljaju u jedan kalup i pri tome obuhvataju jednu vazdušnu komoru, pri cemu kalup potom zatvori a vazdušna komora pod pritiskom naduva, tako da polazni materijali nalegnu na unutrašnje strane kalupa i obrazuju jedno šuplje telo, da bi se potom šuplja smučka stvrdnula, ima za novost to što je vazdušna komora načinjena od dva odsečka jednog dvostrukog creva (6; 7). Pri tome se kod svakog odsečka dvostrukog creva (6; 7) na jedno za vazduh nepropusdjivo, tanko i istegljivo unutrašnje crevo (6) od plastične mase navlači jedno spoljnje crevo (7) načinjeno od neke vlaknaste tkanine, pa se to spoljnje crevo (7), nakon što se natopi nekom sintetičkom smolom, naduva pomoću unutrašnjeg creva (6), tako da bude pritisnuto kako na deo koji čmi osnovnu ploču (1), tako i na materijal (5) koji se sastoji od vlaknaste tkanine, takođe natopljene sintetičkom smolom, a koji sačinjava spoljnji sloj šupljeg tela (4), a u središnjem području šupljeg tela (4) na spoljnje crevo (7) drugog odsečka dvostrukog creva (6; 7). Tako se obrazuje jedno vertikalno rebro (8) koja se pruža u uzdužnom pravcu šuplje smučke, pri čemu se svi delovi stvrdnjavanjem međusobno čvrsto spajaju i obrazuju noseću strukturu šuplje smučke.PROCEDURE FOR MAKING A HOLLOW SKI AND A HOLLOW SKI MADE OF FIBER REINFORCED PLASTIC, the starting materials comprising the plate as well as the material from which the outer layer of the hollow body is made, are placed in a mold and comprising a single air chamber, the mold then closes and the air chamber inflates under pressure, so that the starting materials rest on the inner sides of the mold and form a hollow body, and then the hollow ski hardens, it is new that the air chamber is made of two sections of a double hose (6; 7). In this case, at each section of the double hose (6; 7), one outer hose (7) made of some fibrous fabric is pulled onto one airtight, thin and stretchable inner hose (6) made of plastic, so that the outer hose (7) ), after being soaked in a synthetic resin, is inflated by means of an inner hose (6), so that it is pressed both on the part that touches the base plate (1) and on the material (5) consisting of fibrous fabric, also soaked in synthetic resin, which forms the outer layer of the hollow body (4), and in the central region of the hollow body (4) on the outer hose (7) of the second section of the double hose (6; 7). Thus, one vertical rib (8) is formed, which extends in the longitudinal direction of the hollow ski, whereby all the parts are firmly joined together by hardening and form the supporting structure of the hollow ski.
