CA 2182492

Elongate products are moulded in a die (27, 28 47) from fibre reinforced plastics by drawing a bundle of tows (23) through a bath (16) of resin (17) and between two portions of an open die (27, 28, 47), which is closed under high pressure are heated to cure the resin. The die is opened, and the product is then partly withdrawn lengthwise, to draw further wetted tows (23) between the die portions, and the die is again closed, clamping the tail end of the already cured product which still projects into the die space, or clamping blocks (41) at its downstream end. Cold clamping blocks (24) also clamp the tows (23) at the die upstream end. The products are subsequently severed externally of the die by cutter wheels (44).

Les produits allongés, produits à partir de plastique armé de fibres, sont moulés dans une filière (27, 28; 47) par étirage d'un faisceau de filasse (23) dans un bain (16) de résine (17) et entre les deux parties de la filière ouverte (27, 28; 47), qui est fermée par application d'une pression élevée et chauffée pour durcir la résine. On ouvre la filière et l'on retire partiellement le produit dans le sens de la longueur pour faire étirer davantage de filasse (23) mouillée entre les deux parties de la filière qu'on referme ensuite, serrant la partie arrière du produit déjà durci qui se trouve encore dans la filière, au moyen de blocs de serrage (41) placés à l'extrémité aval de la filière. La filasse (23) est également serrée au moyen de blocs de serrage froids (24) placés à l'extrémité amont de la filière. Les produits sont ensuite coupés à l'extérieur de la filière, au moyen de disques de coupe (44).
