FIELD: construction materials, in particular, production of single-layer ornamental and finishing articles simulating natural stone, such as marble or granite. SUBSTANCE: processing line has multiple-cavity cassette-type hermetically sealed mold positioned upstream of thermal-humidifying chamber and provided with polished partition walls. Multiple-cavity mold is positioned for rotation through 90 deg about horizontal axis. Partition wall polishing extent is within the range of 6-12 roughness units (from opaque to glossy) depending on required quality of article surface. EFFECT: simplified construction, decreased metal usage, low power consumption, reduced time for producing one article and reduced production cost. 2 cl
