3D Force Measurement Online Sensor

 

During biaxial stretching of film, forces are generated which have to be transmitted through the clip configuration. Especially in simultaneous stretching technology, this is a two-dimensional case in the horizontal film level and additionally a vertical force for the gripper.

 

Proper layout upscale, i.e. for thick BOPET film and also the optimization of the process and properties, requires the knowledge of these forces. For that reason the Brückner pilot line was equipped with a newly developed 3 D-sensor which detects three force components on LISIM® clips during the sequential or simultaneous production process of various polymer films.
