Abstract
Abstract A method of rolling metal sheet articles between the driving rolls, in which the rolls of an adjacent pair are rotated in opposite directions at different peripheral speeds, with tensile forces being applied to the input and output portions of the article by successively enveloping the rolls by the article, at ratios of the peripheral speeds of the rolls equal to the ratios of the thicknesses of the article before and after the rolling in the pair of adjacent rolls and at a speed of movement of the output portion of the article equal to the peripheral speed of the roll rotating at a higher peripheral speed, while maintaining a constant pressure on the rolls regardless of any change in the distance therebetween.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
181 words
A method of rolling metal sheet articles by reduction of an article between drivIng rolls, comprising the steps of: imparting to a pair of adjacent rolls the rotation from individual motors in opposite directions at different peripheral speeds; applying to input and output portions of the article tensile forces smaller than a force necessary for the plastic deformation of the article through successive enveloping of the rolls of said pair by means of the article under tension at equal ratios of the peripheral speeds of the rolls and the thicknesses of the article before and after the rolling in the pair of adjacent rolls and at a speed of movement of the output portion of the article equal to the peripheral speed of the roll rotating at a higher peripheral speed; maintaining, by means of a hydraulic head, a required constant pressure on the rolls sufficient for the plastic deformation of the article by way of its reduction with the rolls, which permits attaining the required deformation of said articles regardless of any change in the distance between the above rolls.

Claim 3
Independent Claim
186 words
The method of rolling metal sheet articles by reduction of an article between driving rolls, comprising the steps of: imparting to the pair of adjacent rolls the rotation with the aid of a mechanical transmission from one motor in opposite directions at different peripheral speeds; applying to input and output portions of the article, tensile forces smaller than a force necessary for the plastic deformation of the article by way of successive enveloping of the rolls of said pair by means of the article under tension at equal ratios of the peripheral speed of the rolls and the thicknesses of the article before and after rolling in the pair of adjacent rolls and at a speed of movement of the output portion of the article equal to the peripheral speed of the roll rotating at a higher peripheral speed; maintaining, by means of a hydraulic head, constant pressure on the rolls, sufficient for the plastic deformation of the article by way of its reduction with the rolls, which permits attaining the required deformation of the article regardless of any change in the distance between the rolls.
