Definitions
- This invention relates to a method for splitting chipboard so as to obtain two sections, each having the same area as the original board.
- the board is split in such a way that the surface texture of each section is determined by the manner in which the glued fibres are torn apart from one another.
- this invention relates to a device which allows this splitting to be effected in accordance with this method.
- the latest developments in design for interior and exterior cladding and panelling materials for houses and buildings show a clear tendency towards the choice of natural products such as stone or timber and wood. This has in turn affected the amount of selection and varieties available in surface texture and aspect. Clients are no longer satisfied with plain wood panelling or painted chipboard.
- US-3.554.250 presents a method and a device for feeding a board or a piece of solid wood against a saw blade and thus divide the board into two parts, each part having a sloping surface.
- Figure 1 Wedge-shaped knife which splits a piece of chipboard, and rollers which feed the board towards the knife.
- FIG. 1 This shows the design of the knife itself, its edge and how it is held between jaws.
- FIG. 4 This figure shows the movement effected by the knife.
- Figure 1 shows how a set of rollers (3) feed a piece of chipboard (2) towards a wedge-shaped knife (1) so that the feeding speed remains even and the board can be directed at a correct angle against the knife (1).
- These rollers exert a constant pressure on the board (2), thus preventing the formation of cracks.
- the board (2) is split into two sections, not by a cutting action but by a wedging action. The surface texture of those two sections will depend on how the fibres, which are glued together, will tear away from one another to give a rough and uneven surface.
- the knife (1) is sharpened with a constantly increasing angle towards the blade edge. This is meant to give a wedge effect. See figure 1.
- the knife is undulated in both the horizontal and vertical planes. It is fixed between a set of jaws (4). These are connected to vibrators which impart a rotating motion to the knife(1) in its main plane.
- Figure 4 shows how this rotating motion is imparted to the knife (1) .
- Figure 3 illustrates how the knife (1) positioned against the edge of the board (2) starts its splitting action as the wavy edge is directed into the board.
- the knife will then respond with an undulatory tension between the jaws (4). This increases the splitting effectiveness and reduces the risks of planing the split surfaces down.

Abstract
Procédé de fendage de plaques de bois, en particulier de bois aggloméré, de manière à obtenir deux sections d'égales dimensions dont les surfaces présentent une texture rugueuse et décorative, et dispositif permettant de mettre en oeuvre ce procédé. La plaque de bois est dirigée entre deux cylindres (3) contre un couteau en forme de coin (1) qui est fixé entre deux mâchoires (4). Les mâchoires (4) confèrent un mouvement rotatif au couteau (1) dans son plan principal. Ces mâchoires (4) sont réglées suivant un petit angle par rapport au plan principal du couteau (1) de sorte que, outre le mouvement rotatif, le couteau se déplace aussi avec un mouvement ondulatoire perpendiculaire au sens de rotation.
