SYSTEM FOR APPLYING COATING ON BLANK Russian patent published in 2017 - IPC B05C5/02 

FIELD: technological processes.

SUBSTANCE: applicator head for the vacuum coating system for coating the blank comprises a collector shell having the first shell plate and the second shell plate opposite the first shell plate. The first shell plate comprises the first shell opening and the first pipeline attachment means attached to the first shell opening. The second shell plate comprises the second shell opening and the second pipeline attachment means attached to the second shell opening. The applicator head comprises the first applicator collector attached to the first shell plate. The first collector of the applicator comprises the first collector plate and the second collector plate. The first plate is attached to the first shell plate and comprises the first collector opening aligned with the first shell opening. The second collector plate is attached to the first collector plate. Between the first and second plates of the collector, the first channel of the applicator is formed. The first channel of the applicator is fluidly connected to the first collector opening and forms the first applicator opening at the first leading edge of the first collector of the applicator. The first leading edge is made complementary in shape to the blank edge. The head additionally comprises the second applicator collector attached to the second shell plate. The second applicator collector comprises the third collector plate attached to the second shell plate and including the second collector opening aligned with the second shell opening and the fourth collector plate attached to the third collector plate. The second channel of the applicator is formed between the third and fourth plates of the collector. The second channel of the applicator is fluidly connected to the second collector opening and forms the second applicator opening at the second leading edge of the second applicator collector. The second leading edge is made complementary in shape to the blank edge. The second applicator collector comprises the first face plate and the second face plate. Each of the first and second face plates is positioned above the first and second leading edges of the first and second applicator collectors, thereby covering at least a portion of each of the first and second applicator openings. The first and second face plates comprise a chamfered edge, each of which is located above each of the first and second applicator openings.

EFFECT: simplification of technological maintenance and increase of the efficiency of the applicator head operation.
