Note!In position controlled mode, the hydraulic moves the roll to the positionsetpoint. In pressure controlled mode the hydraulic presses the roll withthe defined pressure setpoint to the extruded plastic film. Even if youchange the thickness of the plastic film, or when you change the temperature of the rolls, you will get the same forces to the film.Normally you use the pressure controlled mode for the production of verythin plastic films.For changing the gap operating mode, see the following description.
