Abstract

Abstract Translated from French L'enveloppe est produite par moulage par soufflage d'une paraison tubulaire (3) dont la paroi interne présente des aspérités (4) ayant la forme générale de pointes qui assurent ultérieurement l'accrochage mécanique du remplissage sur la paroi interne de l'enveloppe. La paraison est débitée au travers d'une tete d'extrusion dont le noyau (2) comporte des rainures (5), la température du noyau étant inférieure d'au moins 20 degrés C à la température de la filière externe (1). L'invention permet notamment une production plus économique des planches à voile. The envelope is produced by blow molding of a tubular parison (3) whose internal wall has asperities (4) having the general shape of spikes which subsequently ensure the mechanical attachment of the filling on the internal wall of the envelope. . The parison is delivered through an extrusion head, the core (2) of which has grooves (5), the temperature of the core being at least 20 degrees C lower than the temperature of the external die (1). The invention allows in particular a more economical production of windsurfers.
