FIELD: process engineering.
SUBSTANCE: invention relates to method of making composite elements. In compliance with proposed method, cover layer is continuously displaced to apply liquid initial material for foam plastic thereon by fixed perforated tube arranged horizontally and at right angle to cover layer displacement direction. Isocyanate-based rigid foam plastic is used as foam plastic. Liquid initial material for foam plastic is fed to the center of said perforated tube. Said tube features diameter decreasing from its center to edges.
EFFECT: higher quality.
