FIELD: wood working industry.
SUBSTANCE: invention relates to wood working industry and may be used in production of multilayer particle boards. A line to manufacture particle boards comprises a belt conveyor, a machine to generate a chip carpet, a press and a spraying plant installed upstream the press with a valve to supply water. At the same time the line is equipped with an additional spraying plant with a valve installed upstream a shaping machine and a unit to measure warpage of boards installed downstream the press. Outlets of the unit to measure warpage are connected to control inlets of spraying plant valves. Due to development of moisture asymmetry of surfaces in the initial chip carpet, as a result of which mechanical stress occurs in a formed board during pressing that compensate for its warpage, which starts immediately after unloading of a board from the press, warpage in finished boards is eliminated.
EFFECT: invention may be used in production of multilayer wooden boards.
