FIELD: method and device for shaping of plates made in the form of strips for manufacture of attachment members in the mass-transfer columns. SUBSTANCE: method consists in continuous conveying of plate strip from the hopper to the moulding devices and corrugating in the first moulding device, production of edges on it, which form a constant slope relative to the edges of the plate strip. After conveying of corrugated strip at least to another moulding device for strip deformation in one or several stages, the edges are removed in the marginal areas outside the middle area of the strip with the aid of a pair of rolls by plastic deformation, and at the same time they are replaced by bent edges, whose slopes continuously grow from the middle area to the edges of the strip. The invention provides for an installation that is provided with the first moulding device for strip corrugating and the second moulding device for deformation of the corrugated plate strip with the aid of a pair rolls containing non-deforming profiles in the middle area, and deforming profiles in the marginal area. EFFECT: provided fine structurization of the plate strip. 10 cl, 7 dwg
