An improved dough sheeting system and method which allow for improved selection of sheeter gap size and which provide a quick release mechanism to prevent damage to sheeter rollers. Hydraulic actuators, attached to a movable roller, hold the roller in a fixed position relative to an opposing roller. The actuators are engaged with a closing force in excess of the force exerted by the sheeted material against the rollers thereby ensuring that the rollers maintain a gap of fixed width. Thermal expansion blocks mounted to the frame or housing of the opposing roller provide a means for fine adjustments in the sheeter gap.

Cette invention concerne un système et un procédé de laminage perfectionnés permettant d'améliorer la sélection du degré d'écartement du laminoir et offrant un mécanisme à déclenchement automatique permettant d'éviter que les cylindres du laminoir soient endommagés. Des actionneurs hydrauliques, fixés à un cylindre mobile, maintiennent le cylindre en une position fixe par rapport à un cylindre opposé. Les actionneurs sont enclenchés par un excès de force de fermeture de la force exercée par le matériau laminé contre les rouleaux, ce qui garantit que les cylindres maintiennent un écart de largeur fixe. Des blocs de dilatation thermique montés sur le cadre ou logement du cylindre opposé offre un moyen de régler avec précision l'écartement du laminoir.
