METHOD OF PRODUCING WALL MATERIAL

摘要

FIELD: process engineering. ^ SUBSTANCE: proposed method comprises producing outer cylindrical surface and lengthwise packing groove. Said outer layer is made by coiling glued laminar material with veneer face layer on cylindrical mandrel with lengthwise groove on outer surface. Veneer fibers are oriented parallel with the mandrel lengthwise axis. Aid lengthwise packing layer is produced by fitting said coiled layer into mandrel lengthwise groove. After cylinder is removed from said mandrel heat isolation layer is made by filling material inner space by heater. ^ EFFECT: reduced consumption of lumber, better structural, physical and decorative properties. ^ 6 dwg
