A separator with a uniform weight per unit area can be manufactured wherein the coating liquid is coated onto a base material film using this gravure roll.

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.

A process for continuous manufacturing of steel strips for packaging coated with a passivation layer is provided. The layer is an aqueous passivation solution, the thickness of which is less than 3 ?m and the viscosity of which is less than 1.5.Math.10.sup.?3 Pa.Math.s at 20? C., and is deposited on one of the faces of the strip. This depositing is carried out by a transfer roller in contact with the strip and with a second coating roller, the surface of which has a plurality of hexagonally shaped cells, the line count of which is between 50 and 200 lines per centimeter, and the total volume of which is between 5.Math.10.sup.?6 and 10.Math.10.sup.?6 m.sup.3 per square meter of roller surface. The coating roller is fed with aqueous passivation solution by dipping in a tank equipped with wiping means and the strip runs at a speed greater than or equal to 400 m/m. An apparatus for implementation of the process is also provided.

A composite glue coating device and a preparation method for a fancy reflective material using the same, which relates to the technical field of reflective material production. The composite glue coating device comprises a composite glue roller (1), a glue coating roller (2), a glue sink device (3) and a glue scrapping device (4). The composite glue roller (1) and the glue coating roller (2) are arranged as a clamping roller set and a bead planting film passing interval (L) is formed between the composite glue roller (1) and the glue coating roller (2). The glue scrapping device (4) is connected with a scraper of the glue coating roller (2). A plurality of glue moving grooves (5) are evenly distributed on the glue coating roller (2). The glue coating roller (2) is connected with the glue sink device (3) and is glue immersed. The glue coating roller (2) rotates to transfer the glue (9) inside the glue sink device (3) into the glue moving grooves (5) and to coat the plating layer (13) of the bead planting film (6) with the glue (9) inside the glue moving grooves (5).
