A process and a line is for the production of hydraulic binder boards having tapered cut ends, the hydraulic binder being in particular gypsum. The process includes: i) spraying a softening liquid on at least one cut end ( 24 a, 24 b) 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 ( 24 a, 24 b) of said hydraulic binder board ( 24 ). According to another aspect, the process includes moving at least one first and one second hydraulic binder boards ( 24 ) on a conveyor; and applying pressure on the cut ends ( 24 a) of said hydraulic binder boards ( 24 ). |
