PCT No. PCT/EP95/03306 Sec. 371 Date Apr. 24, 1997 Sec. 102(e) Date Apr. 24, 1997 PCT Filed Aug. 18, 1995 PCT Pub. No. WO96/06715 PCT Pub. Date Mar. 7, 1996The invention relates to a method and apparatus for metering and distributing pouring material (1) comprising a mixture of wood fibres or such base materials and a mineral binding agent for the production of chipboards, fibre boards or particle boards, especially cement-bonded particle boards, wherein the pouring material (1) is metered volumetrically and the volume and/or weight of the supplied pouring material (1) is controlled, such that along the length and also across the width of the boards to be produced a regular distribution is obtained. Starting from a supply bunker (2) and through a pivotal belt (3) the pouring material (1) is metered to an intermediate supply bunker (7) which in a metered manner supplies a stream of pouring material (1), being regular during the course of time as well as transversely to the direction of supply, to a metering belt (17) which distributes the material on top of a mould belt (22), in such a way that a uniform specific weight and a uniform distribution of the pouring material (1) across the entire surface of the complete boards are obtained. |
