Abstract (en)
[origin: WO2004007162A1] This invention relates to a process and a line for the production of hydraulic binder boards having tapered cut ends, the hydraulic binder being in particular gypsum. According to one aspect of the invention, the process comprises the steps of i) spraying a softening liquid on at least one cut end (24a,24b) of the board (24); ii) waiting for the softening liquid to penetrate the board (24); and iii) applying pressure on said at least one cut end (24a,24b) of said hydraulic binder board (24). According to another aspect of the invention, the process comprises the steps of - moving at least one first and one second hydraulic binder boards (24) on a conveyor; -applying pressure on the cut ends (24a) of said hydraulic binder boards (24).
