ABSTRACT:
This invention describes a process and an apparatus for the raster-formed coating of web-shaped flexible flat articles (3) with hot-melt adhesives in a screen printing process by filling all perforations of a rotary screen printing stencil (1) by means of an outer blade (6) with a solution or dispersion of a paste (2), by placing the flat article (2) on the rotary screen printing stencil (1) and by subsequently additionally applying a paste (5) by means of an inner blade (4). On the finished product, paste (2) produces a plastic base layer which is not or only slightly capable of thermal activation and paste (5) produces a hot-melt adhesive top layer which is easily capable of being thermally activated. Following the drying and sintering of the double-layered printed flat article (8), it can be used as an attachable inlay material for items of clothing.
