  • the sheet 3 for the skin layer and the sheet 2 for the intermediate layer are overlapped and applied to 1. This is due to the vacuum forming force acting through the breathable skin layer sheet 3 through the intermediate layer sheet 2 and the skin layer sheet 3 and the intermediate layer sheet.

If the sheets are weakened and the sheets 2 and 3 can be sufficiently vacuum formed, temporarily tighten the sheet 5 for the skin layer and the sheet 2 for the intermediate layer to temporarily remove the sheet periphery. It is sufficient to adopt a clamp configuration to block the inflow of outside air.

Abstract

Procédé de production d'un article moulé composite (A), composé en laminant une couche de base (1), une couche de matériau intermédiaire (2) et une couche de matériau de surface (3). Un des objets de la présente invention consiste à obtenir une production de masse efficace d'un article composite gauche tel qu'il est décrit ainsi qu'un finissage aisé du bord de blindage des faces périphériques et d'extrémité de l'article moulé en enveloppant l'extension (3) de la couche de matériau de surface (3). La couche de base (1), la couche de matériau intermédiaire (2) et la couche de matériau de surface (3) sont produites ou moulées séquentiellement par une série de procédés continus associés à un procédé de moulage dans le vide et de moulage par injection de résine ou par pression, ou par un procédé de moussage et de moulage de perles de résine utilisant des moules fendus (5), (6) et un moule auxiliaire (7) ayant une configuration spécifique incorporant une fonction de moulage dans le vide, permettant ainsi de laminer intégralement les couches respectives et d'obtenir l'article moulé composite désiré.
