 werden. Beim Pressen ist dafür Sorge zu tragen, dass allfällig eingeschlossene Luft entweichen kann. 



   DieVerwendungder drei Schaumstoffstäbe mit Zwischenlage des harzdurchtränkten Glasfasergewebes ermöglicht es, einen sehr torsionssteifen Ski zu erhalten. Diese Wirkung wird erhöht, wenn darauf geachtet wird, dass die Glasfasern im wesentlichen in Richtung der auftretenden Spannungen verlaufen. Die längsgerichteten, parallel verlaufenden Glasfasern (Roving) nehmen die Biegespannungen auf. 



     Dadurch, daB der minière Schaumstoffstab   7 keilförmig ist, wird beim Pressen mittels des Stempels 12 ein seitlicher Druck auf die Gewebeschicht 5 und die Schaumstoffstäbe 6 ausgeübt. Dadurch wird eine gleichmässige Verteilung des Klebstoffes herbeigeführt.

 will. When pressing, care must be taken that any trapped air can escape.



   The use of the three foam rods with an intermediate layer of the resin-impregnated glass fiber fabric makes it possible to obtain a very torsionally stiff ski. This effect is increased if care is taken that the glass fibers run essentially in the direction of the stresses occurring. The longitudinal, parallel glass fibers (roving) absorb the bending stresses.



     Because the minière foam rod 7 is wedge-shaped, lateral pressure is exerted on the fabric layer 5 and the foam rods 6 during pressing by means of the punch 12. This brings about an even distribution of the adhesive.

PATENTANSPRUCH : Ski, welcher mit einem Mantel aus Glasfaserlaminat und einem Kern aus Schaumkunststoff hergestellt EMI2.1 vinglagen (4, 5 bzw. 10) angeordnet sind, wobei mindestens die oberste Glasgewebeschicht (5) zwei äussere Schaumstoffstäbe (6) umhüllt und sich die beiden Längsränder dieser Glasgewebeschicht (5) überlappen und dass zwischen den beiden äusseren Schaumstoffstäben (6) mindestens ein weiterer Schaumstoffstab (7) von trapezförmigem Querschnitt eingekeilt ist, dessen Oberseite mit mindestens einer Rovinglage und den sich überlappenden Enden einer äusseren Glasgewebeschicht bedeckt ist. PATENT CLAIM: Ski, which is made with a shell made of fiberglass laminate and a core made of foam plastic EMI2.1 vinglagen (4, 5 or 10) are arranged, with at least the top glass fabric layer (5) enclosing two outer foam rods (6) and the two longitudinal edges of this glass fabric layer (5) overlap and that between the two outer foam rods (6) at least one Another foam rod (7) of trapezoidal cross-section is wedged in, the top of which is covered with at least one roving layer and the overlapping ends of an outer glass fabric layer.
