Abstract
<PICT:0917255/IV(a)/1> <PICT:0917255/IV(a)/2> <PICT:0917255/IV(a)/3> A method for the manufacture of pressed boards from wood particles provided with bonding substances comprises the steps of scattering particles on to a base to form a blank, slipping the base and blank between the platens of a press, after which before the press is closed the supporting base is withdrawn from under the blank and the latter is deposited on the lower plate of the press. In one embodiment of the invention chips are spread on a rigid supporting base which is then inserted between press platens. A stopping plate is then brought into action as the supporting base is withdrawn back towards the blank forming station. The leading edge of the supporting base may have an air jet mounting to sweep the press platens clean during loading. In a second embodiment the supporting base is flexible and, after the blank has been formed, the base passes through the press and the base is withdrawn by moving it on in the same direction. In a third embodiment the blank is made by scattering on an endless belt of a transport device which is then inserted in the press. The device is then withdrawn from the press whilst the belt is made to run at the same time, the direction of motion and the speed of the belt being chosen so that the upper surface of the belt remains motionless in relation to the press. In a fourth embodiment a multi-daylight press is used together with a multi-layer loading device. Details of the blank-forming, loading and base-plate removal are given. It is stated that during the removal of the supporting-base from under the blank, the blank remains in position under the press due to its own inertia.
