A method for monitoring the quality of application of an adhesive material (14) onto a moving first film or foil web (12), in particular for monitoring the quality of the adhesive application during a lamination process, comprises:
moving the first film or foil web (12) in a longitudinal direction (x);
applying an adhesive material (14) as an adhesive material layer (15) over the whole surface or in a pattern onto the moving first film or foil web (12);
sensing radiation originating from the adhesive material (14);
determining a detected value representative of a characteristic of the whole surface or the pattern from the sensed radiation;
comparing the detected value with a reference value representative of a desired standard for the characteristic; and
outputting a signal in accordance with the comparison result. |
