FIELD: process engineering.
SUBSTANCE: invention relates to production of composite articles and to device for application of liquid reaction mixes onto cover layer. Composite articles consist of at least one cover layer (b) and solid isocyanate-based foam plastic (a). Cover layer (b) is continuously displaced while initial material for solid isocyanate-based foam plastic (a) is applied on said cover layer. Application of liquid initial substance for solid isocyanate-based foam plastic by at least one tube (c) rigidly fixed and arranged parallel with cover layer plane and perpendicular to its motion. Said tube c) is provided with holes (f). Mix (a) is fed at tube centre while length of holes (f) decreases from tube centre to its ends.
EFFECT: higher quality of composite articles.
