The method according to any one of paragraphs. 1 - 3, characterized in that the angle of entry at the first wall-sinking ring is A: C o , where A is selected in the range 560 - 1280, and C represents the number of moves per minute in the production of cans. 5. Способ по любому из пп. 1 - 4, отличающийся тем, что в качестве слоя пластика используют материал, который в результате деформации в значительной степени кристаллизуется. 5. The method according to any one of paragraphs. 1 to 4, characterized in that as a layer of plastic material is used, which crystallizes as a result of deformation to a large extent. 6. Способ по п. 5, отличающийся тем, что максимальная степень кристаллизации после утонения стенки, измеренная методом дифракции рентгеновских лучей, составляет по меньшей мере 20%. 6. The method according to p. 5, characterized in that the maximum degree of crystallization after thinning of the wall, measured by x-ray diffraction, is at least 20%. 7. Способ по любому из п. 5 или 6, отличающийся тем, что полиэтилентерефталат с точкой плавления более 240oС и вязкостью более 0,6 используют в качестве слоя пластика, который наносят на стальной лист слоем толщиной 15 - 30 мкм.7. The method according to any one of p. 5 or 6, characterized in that polyethylene terephthalate with a melting point of more than 240 o With a viscosity of more than 0.6 is used as a plastic layer, which is applied to a steel sheet with a layer thickness of 15-30 microns.
