Patent number: 11738495Abstract: The invention relates to an apparatus for automatically analyzing extruded films, in particular stretched films, wherein a neck-in portion is formed at each of both edges of the film at a specific distance from an extrusion lip of a film extruder along the longitudinal transport direction of the film, and a respective method. The apparatus comprises two edge detectors being arranged along a first line substantially transversal to the longitudinal direction and being spaced from each other by a specific distance, wherein each one edge detector is configured to detect, preferably to continuously detect the lateral position of one respective edge of the neck-in portion of the film, a calculation means for determining the spatial relation between at least one lateral position at the extrusion lip and a respective lateral position at the neck-in portion on the basis of the two lateral positions of the edges of the neck-in portion of the film.Type: GrantFiled: June 30, 2020Date of Patent: August 29, 2023Assignee: ELECTRONIC SYSTEMS S.P.A.Inventor: Florinda Martena
