Abstract (en)

[origin: ES8104039A1] The present invention concerns the manufacture of objects made of plaster, essentially in the form of boards and, specifically, the pouring onto a moving conveyor of a mixture of plaster and water into a reservoir with an open bottom installed on top of said conveyor. It proposes to integrate the upstream rear wall of the reservoir within a surface of greater dimensions than the rear wall, and displacing said continuously, with the purpose of presenting a different portion of the surface as the upstream rear wall. The invention allows continuous cleaning of the upstream rear wall without disturbing the pouring process.
