Method for producing coatings sticking discrete patterns on a substrate
Abstract:
The invention relates to a method of producing discrete patterns of an adhesive coating on a substrate, comprising the following steps: (a) the substrate is moved continuously or discontinuously in a conveying direction, (b) in an application zone a low-viscosity polymerizable and/or crosslinkable precursor material of an adhesive material is applied two-dimensionally to the substrate through at least one opening of substantially slotlike configuration of at least one movable applicator, a pattern being produced by movement of the applicator relative to the substrate, (c) downstream of the application zone the applied precursor material is polymerized and/or crosslinked.
