Continuously working press with density control

摘要

Continuous press (1), comprehensive - Two endlessly circulating steel belts (3) which pull the pressed material (8) through the press (1) and form a press nip between them for pressing the pressed material (8), - The steel strips (3) supporting heatable heating plates (10), - A roller bearing support arranged between the steel strips (8) and the heating plates (8), - Several frames (2) arranged transversely to the direction of rotation (6) of the steel strips (3) for absorbing the pressing forces, which have several hydraulic working cylinders (4) arranged in a row (R) per frame for pressing the pressed material (8) into a material plate (11) and to adjust the press nip directly into the heating plate (10), and - a control system (20) for controlling and / or regulating the operation of the press (1), characterized in that a measuring device (12) is provided for detecting the bulk density profile of the material plate (11), the control system (20) is set up to control and / or regulate the working cylinders (4) according to a press curve, and the control system (20) comprises an analysis device (23) which receives the measured values recorded by the measuring device (12), the recorded bulk density profile, as an actual raw density profile, analyzed for deviations from a target bulk density profile, and based on the analysis on the Press curve changes to be made to bring the actual bulk density profile closer to or equal to the target bulk density profile.
