Abstract

A method to produce solid glued woodboard (4) out of the glued wood element (1), which is formed by glueing together sawn timber boards (2) or like them, when not glued sawn timber board, free surfaces form glued wood elements main surface and glued woodboards are going to be loosed by sawing out of the glued wood element through elements main surface directed sawing. The element is sawed in the middle split through line (I) and as a result got two halves of the element again in the middle split through line (II) and again as a result got four pieces of the element in the middle split through line (III) and will be carried on, until the desired thickness of the woodboards is reached.

Description

A METHOD FOR MANUFACTURING WOODEN BOARDS BY GLUEING AND A BOARD
The innovation is directed to glued woodboard, which is specially thin and is formed of close together glued sawn timber battens. In addition the innovation is directed to the production method of such solid glued woodboard.
Nowadays is known with different methods produced glued woodboards. One known method is introduced in Finnish patent application FI-794083. According to the innovation glued woodboard is formed out of sawn timber, out of which at least a portion is sawed lenghtwise of the sawn timber and formed pieces of sawn timber are jointed together by glueing in to a woodboard. In the laying of the sawn timber pieces, they are arranged so, that in ready made woodboard the living of the sawn timber causes less possible reformation and cracks to the woodboard.
In the production of glued woodboard the width of the pieces of sawn timber is most suitable a little bit bigger than the thickness of produced glued woodboard. One of the weaknesses of this method is, that against each other glued pieces of sawn timber wideness can vary, therefore the surface of glued woodboard is going to be stepped. The measurement of the steps can even be in the class of 3 mm. Out of that follows, that glued woodboard must be planned in order to get even surface. In the application 794083 given description of the method means that it's very difficult to produce thin glued solid woodboard. In practice with this method produced glued woodboards thickness is at least Apr. 6 mm. All used known methods have restricted the minimum thickness of the glued woodboard to 6 millimeters and the methods have needed a big quantity of wooden raw material compared to the quantity of produced glued woodboard. Typically out of three cubic metres of sawn timber raw material is needed in order to produce apr. one cubic meter ready made thick glued woodboard.
With the new kind of product method of glued woodboard have suprisingly solved the production of specially thin solid glued woodboard without a mentionable waste of sawn timber raw material. Even that produced woodboard is thin, it consists of next to each other glued sawn timber pieces, most suitable those are even thick and even wide. For the invented solid glued woodboard and it's production method is characteristic, what is presented in the patent application. With this invention is going to be reached noticeable advantages, because new, thin glued solid woodboards measurements can be for example widely used 600 mm X 2400 mm and thickness 2 mm - 6 mm. In it's production does not greate mentionable amounts of waste wood raw material and this makes it profitable coverplate to install both straight surfaces and curved surfaces, what has not been possible with the previous glued woodboards. With the invented sawing method can be succeed in the loose sawing of thin woodboard and kept it equally thick through out the plate.
In the following explanation the innovation is introduced closer by pointing to the attached drawing, where
Figure 1. presents glued sawn timber element, out of which woodboards are going to be sawed loose with the invented method. Figure 2. presents the sawing performance. Figure 3. presents the glued woodboard.
Glued sawn timber element 1. in figure 1. has produced out of several, widewise equal, sawn timber boards or planks, as such known method. Boards 2. are put into a stack, one on top of another, when one against another boards sides 3. are glued together. Produced glued woodboards 4. in order to expand the strength and straightness, it's profitable to notice the woods grains 9. (figure 3.) directions, when the boards or planks are stacked, should, when looking from the end of sawn timber, grain directions should take turns between the sawn timber next to each other, most likely in the 90 degrees turns.
The boards 2. are shaped right-angled by the cross section and planed from the surfaces 3. to be glued. During the glueing process glued sawn timber elemeni: 1. is going to pressed against the sides 3. perpendicular direction with the powers F 1 , F2. Out of the element is sawed, after the glue has dried, glued woodboard plates 4. loose in the direction of the elements side surface.
According to the innovation, the sawing is going to be done along the lines I, II III .... and so forth, that way that always the blank is going to be sawed split from the centre of the blank. In the start is going to be sawed line I, as result got two pieces are going to be sawed along the line II and as the result got four pieces are going to be sawed split along the lines III and carry on until the final result is desired woodboard thickness in all the pieces. With this sawing method the saw blade is directed and stays well in the middle of the blank just in accurately follows the sawing line, because thicker and also thinner blanks are opened always symmetrically during the sawing. To the saw blade 5. does not have any effect of any side directional forces, what would bend the blade out of the element. The blade 5. will advance straight ahead even in the thin element. If the sawing would be done close to the other side of the element 1. for example out of the distance of 3 mm, the thin loosing plate would bend behind the blade 5. and the element would stay stiff. This would cause unsymmetrical forces to the blade.
In the figure 2. will show a suitable saw to the method, which blade 5. is a linear blade. The blade does back and forth movement or it is a band saws blade, when it works with continues one directional movement. The saw cut 6. which is left behind the blade stays, due to the symmetry, also in the centre of the sawing line. Also, in the both sides of the blade 5. are the friction forces and circumstance the same. The element 1. is going to be concentrated with respect to the blade for example with the help of movable controls 7. As a controls are most suitable slide rails or rotating rolls.
The saw surface of the element can grind before loosing the following glued woodboard, then the next loose sawed woodboard 4. does not have to grind, if only the other surface of the woodboard must be grinned.
In figure 3. is ready made glued woodboard 4. which thickness d is in between 2 mm - 6 mm. By sawing loosed woodboards wideness can go up to 600 mm and even one meter and length at least 2 - 2,4 metres. Board consists of sawn timber pieces, which are side by side 8. and are length wise same as the length of the woodboard and which wideness is bigger than the thickness.
In most of the usage purposes of the woodboard, it is jointed with glue to the desired surfaces, also to the curved surfaces, which outer surface is wanted to be wood.
