A vibrating smoothing device or plate transverse to a direction of travel of deposited gypsum-cementitious slurry and embedded chopped fibers. The plate is used to smooth the top surface of the slurry panel as it exits a first fiber embedment station and a second slurry depositing station before passing through a second fiber embedment station of a structural cementitious panel production line to remove grooves and other non-uniform surface imperfections to have the slurry cover the embedded fibers The plate is designed to float over the surface of the formed slurry without tearing or otherwise damaging the surface of the heavily fiber reinforced surface layers of the formed slurry before it sets. The vibrating plate is pivotally mounted on the web production line so it can float over the panel surface during use, but be raised off the line when not in use.

La présente invention concerne un dispositif ou plaque de lissage vibrant transversal à une direction de déplacement de coulis de ciment gypseux déposé et de fibres coupées encastrées. La plaque est utilisée pour lisser la surface supérieure du panneau de coulis lorsqu'il sort d'un premier poste d'encastrement de fibres et un second poste de dépôt de coulis avant de passer à travers un second poste d'encastrement de fibres d'une chaîne de production de panneaux de ciment structurels pour éliminer des rainures et autres imperfections de surface non uniforme pour faire en sorte que le coulis recouvre les fibres encastrées. La plaque est conçue pour flotter par-dessus la surface du coulis formé sans déchirer ou autrement endommager la surface des couches de surface fortement renforcées par les fibres du coulis formé avant qu'il ne durcisse. La plaque vibrante est montée de façon pivotante sur la chaîne de production d'armature de sorte qu'elle puisse flotter par-dessus la surface de panneau au cours de l'utilisation, mais soit levée à partir de la chaîne lorsqu'elle n'est pas utilisée.
