Abstract

Le procédé selon l'invention consiste à préparer une matière crémeuse pouvant mousser et dont la réaction chimique a été déclenchée, à avancer une auge mobile horizontalement continuellement avec la matière pouvant mousser de manière à former une masse moussante 7 et à utiliser un moyen presseur 8 pour presser la surface supérieure de la masse moussante 7 sur une zone s'étendant d'un point situé juste avant l'achèvement du moussage jusqu'au point d'achèvement du moussage et à rendre ainsi plate la surface supérieure de cette masse, le moyen presseur 8 se déplaçant horizontalement en synchronisme avec l'auge et dans la même direction que celle-ci Application : plaque en matière plastique pour la fabrication de matelas et de coussins.
