Un cylindre d'élévation (41) est agencé sous le châssis de base (204) pour l'élévation du châssis de base (204). Une tête de mélange (21) est accouplée à la plaque arrière (20). Une plaque de compression avant (11) est accouplée derrière la plaque avant (10) de sorte que la plaque de compression avant (11) soit mobile dans les directions avant et arrière. La plaque de compression avant (11) se déplace vers l'arrière depuis la plaque avant (10) de manière à former un espace pour un gabarit de moussage de produit et à assurer l'étanchéité de la surface avant du gabarit de moussage de produit. Selon la présente invention, une phase d'expansion et de rinçage de mousse peut être considérablement accélérée et les parois creuses de l'armoire peuvent être complètement remplies de mousse en un temps relativement court.
