Abstract

1,190,816. Extrusion moulding of chip board laminates. A. G. ZU ERBACH-FURSTENAU. 19 May, 1967 [21 May, 1966], No. 23272/67. Headings B5A and B5N. [Also in Division C3] Particled wood board in which the chips in the surface layers are bent or oriented parallel to the extrusion direction is made by feeding wood chips and a binder from a hopper 1 through a heated extruder 2 by means of a reciprocating plunger 4, the emergent board being not quite set, and then passing the board through a pair of compression rolls. In a modification, Fig. 4 (not shown), the inner faces vary in diameter from a wide section (a 1 ) adjacent the plunger to a narrower lower section (a 2 ) of the width of the plunger, the parts (a 1 ), (a 2 ) joining at a rib (18). Passage of the chips over the rib (18) partially orientates them. In a further embodiment, Fig. 5 (not shown) two extruder sections of width (a 2 ) are spaced by a wider section (a 1 ). In every embodiment the compression rolls may be followed by one or more pairs of additional rolls, by stationary or vibrated plain compression members or by endless belts 12. The inner faces of the heated extruder plates 2 may be provided with projections and recesses to aid chip orientation. The compression and additional rolls may be heated, may be positively driven above or below the board speed and may be fixed or resiliently mounted. Also paper, plastic or metal foil 8 may be applied to one or more surfaces of the board from drums 7, the board and/or foil being sprayed with adhesive from the nozzles 6. The foil may pass round the compression rolls 9. The moisture content of the board and/or paper may be controlled to provide a built-in stress in the finished board.
