| 摘要 |
A system for moving toward and away from the working zone of a laminating cylinder (2) sustained at its ends in bushings of two movable supports (1) and for automatically regulating the lamination gap during treatment of a material in a calender or mixer machine, comprises position sensors (10) of the two mobile supports (1) of the cylinder, a central signal processing and control (15) unit, a drive interface (14) of distinct movement actuators of the two supports. Each support is shifted during a positioning phase of the cylinder as well as during the automatic regulation of the gap of lamination in operation, by a single hydraulic cylinder (4) and employing a single transducer for sensing the relative spatial position of the support. The interface drives pairs of control valves (12) of the respective hydraulic cylinders (4) in digital mode and in a closed loop mode during all phases of operation.
