    @ A method of mending a defective wood plate (12) uses, instead of putty, a solid patching material (18) which is smaller in thicknesswise shear strength and compressive strength than the wood plate (12) and is sized greater than a defect of the plate which is to be mended. The solid patching material (18) is applied to the plate in such a manner as to cover the defect (20) and, then, compressed in the thicknesswise direction to undergo shear fracture. As a result, that part of the material which overlies the defect is thrusted into the defect. The compression is effected in two consecutive stages, one using a rigid member and the other an elastic member. The part of the material (18) filled in the defect (20) is separated from the other part which remains on the plate (12). Where this method is applied to plywood production. the material (18) will be forced into the defect (20) without resorting to an extra compression step while the plate is being bonded to another.

    FIG.
    I The invention relates to the woodworking industry and, in particular, to plywood manufacturing.
    The purpose of the invention is to increase the pro- ductiveness of defect correction by simplifying the preparation and pressing of inserts.
    Fig. 1 is a diagram of a device for managing defects, a view of a side; figure 2 is a diagram of a wood with a defect, side view; FIG. 3 is a schematic diagram of a device with a wood board having a non-through defect, side view; figure 4 - diagram of the device with an elastic roller; in fig. 5 and 6 is a diagram of a wood board with a defect and an insert; Fig. 7 is a diagram of the device with a grinding roller; on Fig diagram of the device with different-sized rollers and an elastic layer; Fig. 9 is a schematic diagram of a device for correcting defects in the manufacture of a wood-burning plate, the initial period; on “d.10 - the same, the final period; on .11 - diagram of a wood board with corrected defects, top view.
    A device for correcting defects of veneer boards, plywood, sawn slabs and other wood plates - BLUE includes a conveyor 1 for transporting a wood board 2, a supporting 3 and a pushing 4 rollers mounted one above the other, above the area of the reflect 5 there is an insert 6, additionally behind the support 3 and pressure 4 rollers, a support roller 7 with an elastic element 8 or a support roller 9 with a grinding element 10 can be mounted, or the function of pressing the insert 6 into the defect zone can be performed by the support 1 and pressure 12 plates.
    The method for correcting defects of wood board is carried out as follows.
    On the conveyor 1, a wood plate 2 with defect 5, which has been used, is laid down.
    covered with insert 6. Conveyor I feeds wood plate 2 to support 3 and pressure A rollers, the latter are pressed in insert 6 into the zone of defect 5.
    The pressing of the insert 6 into the zone of the defect can be done using the support M and the pressure 12 plates.
    After pressing in, the face plane of the insert 6 is affected by an elastic 8 or a grinding element 10, and the defect correction cycle is repeated.

    Claims (2)
    [1]
    1. A method for correcting defects of a wood plate, including laying a wood plate with a defective area, and preparing a solid material for an insert, the ratio of the insert thickness to the thickness of the wood plate being 1.0-1.7. , compressing the material for the insert and the wood board, forming the insert and pressing it into the place of the defect of the wood board, characterized in that, in order to improve the performance of the defect correction by simplifying the sub-. preparing and pressing inserts; the insert material has a lower shear strength and compressive thickness than the wood board, and its area exceeds the area of the defective area; the insert formation is carried out together with the compression of the insert material, and the compression is
    with shear fragmentation of the material for insertion on the edges of the defective area of the wood board.
    [2]
    2. The method according to claim, characterized by the fact that the material for the insert of the plate is compressed by means of a rigid and then elastic elements.
