Surface inspection of adhesive film

The plastic manufacturing industry has seen an increase in the demand for adhesive film in recent years. While fulfilling these demands, it is also mandatory to examine the surface well for depressions and folds, in order to keep the customer satisfied. Moreover, the occurrence of such faults in the film leads to wastage, making the film unusable. To cope with these problems, a laser scanner is used to evaluate a film for any defect along the total length of the film.

The scanCONTROL 2910-100 laser scanner by Bestech Australia offers such measurement options for an adhesive film by traversing over a width of 1m. On encountering any deviation in the profile of the film, the scanner gives an OK or NOK result and the signals are output via a digital interface and transferred to the control system.
