FIELD: process engineering.
SUBSTANCE: invention may be used for applying lacquer coating in continuous feed of lacquer on surface. In compliance with this method, constant level of dyestuff is created in dyestuff vessel. Said level is maintained by drawoff of dyestuff from additional vessel and varying pressure on dyestuff surface in chamber 7. With dyestuff level decreasing, air bubbles get via opening 10 of plug 8 into free space above dyestuff surface in said chamber to increase pressure on fluid column. Dyestuff 11 starts flowing from chamber 7 to resume is level in vessel 2.
EFFECT: simplified design, ease of use, reduced consumption of dyestuff.
