Abstract

L'invention concerne les appareils de fabrication de pains de mousse. Elle se rapporte à un appareil dans lequel la mousse qui se forme par dilatation sur un transporteur mobile 12 et entre deux transporteurs mobiles, est au contact d'un panneau 26, entre le point de gélification de la mousse et le point auquel la mousse n'est plus mobile. Application à la fabrication de pains de mousse de section bien rectangulaire.
