Abstract
Construction board is made by first hot-pressing particles in a continuous belt press to form a longitudinally extending, continuous and hot composite strand that is conveyed downstream from the press. Before substantial cooling of the boards and while it is at a predetermined temperature above ambient temperature, an edge of the strand is profiled into a nonsquare profiled contour. Then the strand is transversely severed to form a succession of boards.
Claims13
A method for making construction boards, the method comprising the steps of:
- hot-pressing particles in a continuous belt press to form a longitudinally extending, continuous and hot composite strand;
- before substantial cooling of the boards and while same is at a predetermined temperature above ambient temperature, profiling an edge of the strand into a nonsquare profiled contour;
- and
- transversely severing the strand to form a succession of boards.
A system for making construction boards, the system comprising:
- a continuous-belt hot press for hot-pressing particles to form a longitudinally extending, continuous and hot composite strand;
- a conveyor for continuously transporting the strand in a longitudinal travel direction from an outlet of the press through a profiling station and a severing station, the profiling station being within 20 m in the direction from the press such that the strand does not cool substantially from a temperature at which it leaves the press before entering the profiling station;
- means at the profiling station for profiling an edge of the strand into a nonsquare profiled contour;
- and
- means at the severing station for transversely severing the strand to form a succession of hot boards.
The board-making system according to claim 12, further comprising;
- means at a coating station between the profiling station and the severing station for applying a coating to a face of the strand.
