METHOD FOR APPLICATION OF COATING ON STRIPS OF METAL-ROLL, PRODUCTION LINE FOR APPLYING COATING ON STRIPS OF METAL-ROLL Russian patent published in 2018 - IPC B05D5/02 

FIELD: technological processes.

SUBSTANCE: invention relates to a method for applying a coating onto strip metal for manufacturing a semi-finished product with a textured surface structure and can be used as a profiled sheet in facade works, when manufacturing garage doors or housings for household appliances. Said method of coating a strip metal for manufacturing a semi-finished product with a three-dimensional surface structure comprises at least one process step a – preparing a flat metal product and technological step b – application of structural coating and / or paint coating with three-dimensional shaping on the flat metal product. To create a structured texture of the coating and / or paint and varnish, a filtration coating application method is used. In the method, the production line for coating the strip of metal roll comprises at least a filtration coating application unit for the creation on a flat metal rolling a structured coating texture and / or a paint coating with three-dimensional shaping. Further, the installation of the filtration coating allows for the realization of the method for manufacturing a semi-finished product with a three-dimensional surface texture according to any of the preceding claims 1–12. And the semi-finished product includes a flat metal roll with a structural coating and / or paint coating applied using the method for applying a coating on a strip of rolled metal according to any one of the preceding claims 1–11.

EFFECT: technical result of the invention is an increase in the reproducibility and variety of three-dimensional surface structures of semi-finished products.
