20150027618 | METHOD FOR MONITORING THE QUALITY OF AN ADHESIVE APPLICATION DURING A LAMINATION PROCESS - A method for monitoring the quality of an adhesive application during a lamination process for manufacturing a packaging laminate includes conveying a first film or foil web in a longitudinal direction, applying an adhesive material over the whole surface or in a pattern onto the moving first film or foil web and applying a second film or foil web onto the adhesive coated first film or foil web and conveying the first and second film or foil web having the intermediate deposited adhesive material layer in the longitudinal direction to a pressing station to form a laminate. A fluorescent agent may be added to and intermixed with the adhesive material such that the fluorescent agent is uniformly distributed. Fluorescence radiation emitted by an ultraviolet-exposed adhesive material layer is detected by a visual inspection system. | 01-29-2015 |
