Abstract (en)
[origin: EP0003705A2] 1. Process for the manufacture of a band or boards of plaster by casting on a movable casting bed travelling at uniform velocity a mixture essentially of plaster and water contained in a reservoir placed directly over the casting bed at a pressure head with respect to said casting bed, said mixture being cast through a transverse slot which is parallel and adjacent to the casting bed and formed under the downstream wall of said reservoir, characterized in that replacement mixture is continuously introduced in liquid form into the reservoir by a plurality of jets immersed in the mass of mixture already in the reservoir, which jets are spaced apart in such a manner and have such force that they produce in the mixture of the reservoir an agitation the flow lines of which are visible over the whole surface of the reservoir.
