Abstract: The invention relates to a distribution block for extrusion melt and a method for coextruding films with the aid of a distribution block for extrusion melt, wherein the distribution block comprises a movable sleeve.
Abstract: The invention relates to a method for applying polymer patches, in particular from polymer electrode material, on a carrier substrate, including the following method steps: a) plasticizing the polymer electrode material to form a melt, b) feeding the plasticized polymer electrode material via at least one die to a heated, structured roller or to a heated, structured conveyor belt, wherein the roller and/or the conveyor belt have recesses that correspond to the dimensions of the patches to be applied, c) applying the plasticized polymer electrode material on a carrier substrate by bringing the roller and/or the conveyor belt in contact with a carrier substrate.
