Abstract

816,285. Composite wood. GEWECKE, H. Jan. 2, 1958, No. 240/58. Class 145. [Also in Group XXX] Composite wood slabs or rods are made by scattering wood chips and a binder into a mould so that the maximum dimensions of the chips lie within a predetermined acute angle to the longitudinal axis of the slab or rod and then pressing the slab or rod and causing or allowing the binder to set. The angle may be varied, preferably between 10 and 20 degrees, so as to vary the ratio of longitudinal strength to transverse strength and the sizes of the chips may vary from 15-75 mm. long, 2-10 mm. wide and 0À1-0À5 mm. thick. The orientation of the chips may be produced by variable air currents or magnetic or electrostatic fields or by a tapered compartmented box a in which the outlets c of the compartments have widths which are less by the required amount than the length of the chips. The slabs may be made in continuous lengths or in limited lengths by moving a mould d backwards and forwards under the box a so that the chips are deposited in layers.
