Definitions

• the innovation is directed to glued woodboard, which is specially thin and is formed of close together glued sawn timber battens.
• the innovation is directed to the production method of such solid glued woodboard.
• 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.
• 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.
• 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.
• 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.
• 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.
• the thin loosing plate would bend behind the blade 5. and the element would stay stiff. This would cause unsymmetrical forces to the blade.
• FIG 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.
• FIG 3. is ready made glued woodboard 4. which thickness d is in between 2 mm - 6 mm.
• 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.
• the woodboard 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.
