ELOVIS Measurement Solutions for Foil Industry

For the film and foil industry, ELOVIS offers irreplaceable measuring solutions both for the permanent optimization and monitoring of production machines and for troubleshooting. An important field of application is the calibrated length measurement during the production of finished rolls, when the product is sold by length or square meter. Also worth mentioning is length measurement in incoming and outgoing goods, in production machines and slitter rewinders, and at all process stages where precise information on material lengths is required. However, µSPEED laser encoders are also used to measure speeds and differential speeds, e.g. to determine elongation and shrinkage of the goods or for speed synchronization when several material webs are brought together. µVIS systems are used to measure the width of films, including single strip widths when the material is cut into numerous strips. ELOVIS SLM longitudinal light sensors are used to measure the length of sheets and width of finished rolls.  Some typical examples of measurement solutions in the foil and film industry are listed here.
