METHOD FOR THE CONTROL OF THE ROTATIONAL SPEED FOR A DRIVE DEVICE OF A PRINTING ROLL

METHOD FOR THE CONTROL OF THE ROTATIONAL SPEED FOR A DRIVE DEVICE OF A PRINTING ROLL

The invention relates to a method for the control of the rotational speed for a drive device (20) of a printing roll (10) having a resilient printing sleeve (12) of a flexographic printing press (100), comprising the following steps: determining a first rotational speed (V1) of the printing roll (10...

Zusammenfassung:The invention relates to a method for the control of the rotational speed for a drive device (20) of a printing roll (10) having a resilient printing sleeve (12) of a flexographic printing press (100), comprising the following steps: determining a first rotational speed (V1) of the printing roll (10) when running freely without an active drive device (20) at a first pressure value (B1), determining a second rotational speed (V2) of the printing roll (10) when running freely without an active drive device (20) at a second pressure value (B2), generating a control curve (30) of the rotational speed in relation to the pressure value on the basis of the determination steps, using the control curve (30) for the control of the rotational speed of the printing roll (10) with drive device (20) active.
