FIELD: production processes.
SUBSTANCE: covering material (1) is obtained by means of extrusion of plastics layer (5) which is connected to layer of absorbing bearer (2). Then bearer (2) is impregnated by reactive resin (6) by means of its distribution on surface or by means of submergence in tar. Resin (6) is absorbed through layer of bearer (2) and contact with plastics layer. Then reactive resin (6) is dried with preservation of groups in it reactive to cross link. These groups undergo reaction of linkage when covering material is connected to rigid sheet based on fibers upon heating and under pressure. End product is obtained in which resin acts as binder between covering material and sheet.
EFFECT: simplification of manufacturing of sheet product and reinforcement of linkage in it between base and covering material containing plastics layer.
