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.
Claims8
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 having an edge of square contour;
- before substantial cooling of the boards and while same is at a predetermined temperature below a temperature at which the strand leaves the press, and above a temperature midway between the temperature at which the strand leaves the press and ambient temperature, trimming and thereby truing the edge of the strand to planarity and thereafter profiling the trimmed edge of the strand into a nonsquare profiled contour;
- and
- transversely severing the strand to form a succession of boards.
