A quick plate press is provided with a plurality of side by side plates (2), which delimit interposed spaces (3) for panels. Said press (1) comprises compression hydraulic cylinders (4) of the plates (2) and translation means (5) which are provided with a plurality of respective linear hydraulic actuators (6) to alternatively position the spaces (3) at opening means (7), fit for reciprocally remove the plates (2) of a space (3) for entering said space (3).
Said press (1) includes:
- proportional valve means (10) for individually driving each actuator (6) of translation means (5);
- a plurality of linear encoder means (11), each thereof associated to a respective actuator (6) of translation means (5);
- control means (12) whose input port is connected to linear encoder means (11) and whose output port is connected to proportional valve means (10).
The control means (12) are fit for driving the actuators (6) of translation means (5) with differences of position or of relative speed, which are lower than predefined threshold values.
