<p>The invention relates to a method for producing plaster plates (44), according to which two fine cardboard-covered sheets of paper (8, 9) enclose a plaster-based hydraulic binder (10) in a shaping device (13), creating a composite band (45) that is hardened on one or several hardening bands (14, 15), the edges of said hardening bands (14, 15) being provided with two bands used for tapering in the horizontal direction. The inventive method is characterized by the following steps: - expandable block-type elements (5) having a small width are prepared in a continuous manner; - said block-type elements (5) are cut, and glue is spread across the upper surface thereof; - the block-type elements (5) are glued crosswise to the bottom of the cream-colored paper (8) in an uninterrupted manner according to a precise step in an area that is necessarily located before the shaping device (13); - the block-type elements (5) are conveyed by the cream-colored paper (8); - the block-type elements (5) which are fixed to the cream-colored paper (8) traverse the shaping device (13), and the composite band (45) is hardened; the block-type elements (5) are removed with a rotary brush (22); the composite band (45) is cut by means of a shear at the level of the imprint (20) left by the block-type element (5).</p> |
