Claim:
A process for applying an active material onto an article, series of articles or web of articles, comprising the steps of: a) applying said active material to a surface of a first tool in the form of a multitude of beads with a coater unit having a multitude of extruder-applicators that are in close proximity to the surface of the tool, and positioned above the surface, said extruder-applicators extruding said active material through a die onto the surface of the first tool; b) heating the coater unit such that the active material is applied at a temperature of between 70 degrees C. and 250 degrees C.; c) contacting the surface of the first tool containing the active material, with a coating blade which has an angle of between 5° and 40° with the tangent of the surface of the first tool, and which applies a constant pressure onto the surface with active material; and d) transferring the active material from the surface of the first tool to an article, series of articles or web of articles, supported on a surface of a second tool and pressed against the surface of the first tool, wherein the temperature of the coater is at least 5° C. less than the temperature of the surface of the first tool.
