Abstract
L'invention se rapporte à un dispositif de pressage par compression à chaud de disques souples. Le dispositif comporte des plateaux chauffants portant chacun une plaque de mousse souple à cellules fermées de diamètre voisin de celui des matrices gravées. Le disque souple à presser est placé entre une matrice gravée et une contre-matrice ou une seconde matrice gravée, l'ensemble étant placé entre les plaques de mousse à cellules fermées de telle manière que lors de la compression, ces plaques de mousse à structure alvéolaire agissent comme compensateur pneumatique et permettent une répartition uniforme de pression sur la surface à graver. Application, notamment, au pressage de disques vidéo lisibles optiquement par un faisceau concentré.
