FIELD: construction.
SUBSTANCE: group of inventions relates to a laminating station for forming laminates of cardboard packages for liquids and a method implemented by said station. Station comprises cooling roll (8), pressure roll (4) parallel to cooling roller (8), support roll (10), intended for displacement of pressure roller (4) towards cooling roller (8), extrusion device serves for application of layer entering the gap between rolls (4) and (8). Station also comprises device (14, 16) for the direction of belts passing parallel to roll (4), left and right endless belts (12) passing over roll (4) and device (14, 16) for guiding the belts and through the gap, between left and right endless belts (12). There are also intermediate endless belts (24) extending over roll (4) and device (14, 16) for guiding the belts and through the gap. Belts 12 serve to prevent contact of applied layer with pressure roll (4). Belts (14) and (16) perform this function and / or function of pressing the external binding layer of the manufactured laminate into the holes through the inner layer of the laminate and, thus, in contact with the most distant from the centre layer of the laminate. Proposed method comprises application of layer on one side of substrate, insertion of substrate into gap between first and second rolls, and removal of substrate and layer from first roll.
EFFECT: technical result achieved by a group of inventions is preventing adhesion of material of extrusion coating with first roll.
