DEVICE FOR COATING APPLICATION Russian patent published in 2020 - IPC B41F19/00 

FIELD: devices for diffusion or spraying liquids; technological processes.

SUBSTANCE: disclosed is apparatus for coating surface, capable of moving relative to said apparatus, layer of thermoplastic particles, wherein said particles stick to surface more than to each other. Said apparatus comprises at least one spray head for direct or indirect application to the fluid medium surface, in which the particles are suspended, a housing surrounding the spray head (s) and limiting the inner chamber for holding the fluid flow, wherein the housing has an edge adjacent to the surface, configured to prevent the particles from leaving the sealing gap formed between the body edge and the surface to be coated, and a suction means connected to the housing to extract the atomised fluid from the chamber and particles suspended in said sprayed fluid. During operation, the suction means removes substantially all particles which are not in direct contact with the surface, so as to leave at the output of the apparatus only substantially one layer of particles which adheres to the surface.

EFFECT: disclosed is a coating application device.
