FIELD: cardboard products.
SUBSTANCE: method for manufacturing cardboard product usable for printing and containing at least two layers includes operation of connection of separate sheets of paper or cardboard by glue with production of combined product. At least one of the sheets is processed mechanically by pressing, to create elements with remainder deformation, which project outwardly from the surface of the sheet for height which ensures thickness of the sheet, which in turn does not exceed 3 millimeters. The sheet, subjected to mechanical processing, is processed in dry state with content of moisture in the sheet below 12%. Claimed invention also describes a product of cardboard or paper sheet, which is made according to aforementioned method. Claimed method and product ensure production of cardboard which contains internal sheet, which ensures production of cardboard with good rigidity and good ratio of raw stock flow to rigidity of cardboard.
EFFECT: increased efficiency.
