PRODUCTION LINE OF SHEET MATERIALS Russian patent published in 2002 - IPC

FIELD: wood-working industry. SUBSTANCE: the production line is provided with a fixture for prevention of delamination and variation in thickness of sheet materials, which is made in the form of interconnected sensors of fit of the press plates on the spacers, analog pressure transducer, additional device of the control system, device for pre-setting and representation of the pressing parameters. The sensors of fit of the press plates on the spacers are installed on the lateral sides of the press movable plates in the working planes of the spacers. The analog pressure transducer is connected to the press drive, the additional device of the control system is coupled to the device for presetting and representation of the pressing parameters and positioned on the control desk. The sensors of fit of the press plates on the spacers, analog pressure transducer and the drives of the hydraulic discrete valves are connected to the additional device of the control system. EFFECT: prevented delamination, deformation of spacers and press plates, and as a result, variation of thickness of the ready-made wallboards. 20 cl, 2 dwg
