FIELD: process engineering.
SUBSTANCE: invention relates to production of window section. Proposed unit comprises the main extruder 10 to fuse resin material and to compress and feed fused resin material to head 30, head 30 to output resin material shaped to section of definite shape, calibrator 70 to support the extruded section physical configuration and section cooler 90. Embossing roller 50 for creation of embossed patterns on section surface is arranged between head 30 and calibrator 70. Note here that said embossing roller has first ledge 53 made thereon and second ledge 55 made at said first ledge.
EFFECT: higher quality of embossed patterns, preservation of natural wood texture, fine appearance.
