摘要:
The invention relates to a method for manufacturing a woodchip board (3) comprising a first (21) and second (23) woodchip layer sandwiching an intermediate layer (12) comprising woodchips of other chip size than the first (21) and second (23) woodchip layer. The method comprises the steps involving application of a first quantity (5) of glued woodchips (7) to a lower tool face (9) of a pressing tool (1, 31); application of a filler quantity (11) of glued woodchips (7') to the first quantity (5); application of a second quantity (13) of glued woodchips (7) to the filler quantity (11); compression of said quantities (5, 11, 13) by means of the lower (9) tool face and an upper tool face (15); realization of differentiated times when the glue of the glued woodchips (7) hardens in the first (5) and second quantity (13) respectively, by virtue of the production of these quantities with different thickness and/or by heating of the respective quantities (5, 13) to different temperatures; and removal of the hardened woodchip board (3) from the pressing tool (1, 31).

A panel (11) has a wooden body, which is formed of board-shaped building elements (5) arranged side by side, parallel to each other. The wooden body comprises at least two board-shaped building elements (5), each of which is mad eof two boards (2a, 2d) sawn from a log and having at least partially remaining wane portions (3a, 3d). The boards (2a, 2d) are placed on top of each other and glued together, their narrow faces bearing against one another.

The invention relates to a wood particle board (5) and to a process for the manufacture of the same. The process involves the feed-out of a first quantity (9′) of glue-coated wood particles (25), producing a bottom particle mat (10′), feed-out of a second quantity (9″), comprising a homogeneous mixture of glue-coated defibrated wood particles, for producing an intermediate, voluminous mat (20) on top of the bottom particle mat (10′), feed-out of a third quantity (9′″) of glue-coated wood particles, producing a top particle mat (10′″) on top of said intermediate, voluminous mat (20), and compression of said fed-out quantities, to form a bottom (1), intermediate (7) and top layer (3) of the wood particle board (5).

The present invention relates to a method for manufacturing a wood-based furniture component (24). The method comprises steps in which chips (7) are distributed forming a chip mat (13), the chip mat (13) is compressed by means of a tool surface (19) comprising one or more gaps (21) for forming one or more projecting chip segments (53), forming spacers (5, 63, 71), the finish- pressed chipboard (3) is fed out and the projecting chip segments (53) of the finish-pressed chipboard (53) are joined to another furniture component structural element (3', 47, 49, 73).
摘要:
The invention relates to a manufacturing arrangement for a wooden chipboard and to such a wooden chipboard constructed from two boards (3) adhesively bonded together, each comprising an outward-facing side (5) and an inward-facing side (7), recessed grooves (9) in at least one inward-facing side (7) forming parallel channels (k) in the wooden chipboard (1), and an adhesive surface (11) between the boards (3) in the location between the grooves (9). The adhesive surface (11) between two adjacent grooves (9) in a board (3) constitutes a basic foundation (13) for a support wall (15, 15', 15") formed in the board (3) between the grooves (9) for counteracting the depression of the outward-facing side (5) in the area of the bottom (17) of the groove (9) when the wooden chipboard (1) is exposed to stressing, the groove (9) being formed with an arched shape in its cross section transversely to its longitudinal direction.

The invention relates to a structural member comprising a first and a second board member that are arranged in parallel to each other, and a filler element arranged between the first board member and the second board member. The filler element is a continuous sheet with a sheet plane that is substantially parallel to the first and second board member, and is moulded or vacuum-moulded so that cone-shaped cavity structures project outward from the sheet plane. The cone-shaped cavity structures are provided as truncated cones having a top and bottom, both having a substantially circular shape. One side of the sheet plane has a continuous, flat surface and the cone-shaped cavity structures project outward on the other side of the sheet plane. The cone-shaped cavity structures have a cone angle of approx. 5-45°.

The present invention relates to a particle board comprising a lower and an upper surface layer (9, 11) having a finer fraction of particles (4), and between these surface layers (9, 11) an intermediate layer (13) having a coarser fraction of particles (5). The intermediate layer (13) has a varying density.
