Article-EXTRUSION: Device offers cross-profile web control

This torsion-resistant, box-shaped traverse film and sheet thickness measuring system can handle production of webs up to a maximum of 13m. The process interface is the measuring head, which, at distances of 1 mm above the film, captures the relevant product data in up to 13,000 measurements/cycle. This information is transferred to the plant control where the control unit will intervene to make corrections and compensate deviations from the desired values within a specific tolerance range. A digital measuring head enables the radiometric basis weight sensor within an industrial PC to communicate with this manufacturer’s WIN-CC-based system. This is said to allow process specifications, trends, and quality to be monitored easily by the operator on the shopfloor. Betacontrol GmbH, Freudenberg, Germany; +49 2734 46812;
