Abstract

L'invention concerne un dispositif de production continue de produits en forme de plaques, qui comporte deux courroies sans fin pouvant être entraînées et disposées l'une au-dessus de l'autre (10, 12). Une fente de travail (18) est formée entre les brins des courroies, voisins l'un de l'autre et conduits chacun via une surface d'appui (14, 16). La matière de départ à traiter (20) passe à travers cette fente (18), délimitée de chaque côté par une bande de calage (30) qui se situe le long de la fente de travail (18) entre les deux courroies sans fin (10, 12) et qui se déplace avec ces dernières. La bande de calage (30) est constituée d'un ruban d'étanchéité flexible (36) qui présente, sur au moins un côté large faisant face à la courroie sans fin (12), une surface de frottement (38) augmentant le frottement statique entre le ruban d'étanchéité (36) et la courroie sans fin (12)
