Manufacture and process
THE PROCESS…HOW DOES IT WORK?
- The wood arrives in the form of logs or in bulk at the lumberyard. It is then transformed into chips (for particle board) or slats (for OSB).
- The wood is dried and sorted to form the different layers of the panel.
- It is then glued and placed on the continuous press line.
- Pressing takes place at high pressure and temperature, in order to bake the panel.
- A diagonal saw cuts the panels lengthwise.
- The panels then pass into star coolers and are then cut widthwise before being stacked and stored.
- The slab workshops make it possible to transform Particle Panels (PP) and OSB into slabs (with the shaping of grooves and tongues).
- PP can be used as a support for melamine decorative panels.
- The presses in the melamine workshop allow the decorative paper to be glued to the rough particle board.
- Each panel is visually inspected before stacking, automatic strapping and placing in stock for shipment.
- Some melamine panels can be transformed in the shelf workshop.
CONTINUOUS OSB PRESS FOR OPTIMAL PRODUCTIVITY
After being debarked, cut, dried and sorted, the slats pass through the gluing machines, where they are sprayed with formaldehyde-free glue. The forming machines form a “mat” (called mattress or cake) on a conveyor belt:
- the 1st and the last forming machines form the outer layers and are equipped with guides, so that the slats are in the long direction of the panel.
- the other 2 form the inner layer of the panel.
The mat is pressed at 250°C with a pressure of 300 bar. This process allows the panel to bake and gives it all its technical characteristics. Panels are cut continuously by 2 diagonal saws. They pass into star coolers, to be cooled then cut, stacked, strapped and put in stock, for shipping. 2/3 of the production is machined into slabs: tongues and grooves are added. The panels are used in construction: walls, roofing, floors, wooden frame houses, but also in packaging and increasingly in interior design.
