Claims (8)

1. Способ правки холоднокатаной ленты (2), пропускаемой через комплект (3, 30) тормозящих роликов и комплект (4, 40) растягивающих роликов и в процессе ее растягивания подвергают между обоими комплектами роликов вытяжке, а в дополнительном комплекте (5) роликов, расположенном между комплектом (3, 30) тормозящих роликов и комплектом (4, 40) растягивающих роликов, для повышения коэффициента вытяжки подвергают изгибу с растяжением, отличающийся тем, что с помощью дополнительного комплекта (5) роликов создают основную долю вытяжки.1. The straightening method of a cold-rolled tape (2), passed through a set of (3, 30) brake rollers and a set (4, 40) of stretching rollers and in the process of stretching it, is subjected to a hood between both sets of rollers, and in an additional set (5) of rollers, located between the set of braking rollers (3, 30) and the set of stretching rollers (4, 40), in order to increase the stretching coefficient, they are subjected to stretching bending, characterized in that the main share of the stretching is created using the additional set (5) of rollers. 2. Способ по п.1, отличающийся тем, что ленту в комплекте (5) роликов подвергают знакопеременному изгибу.2. The method according to claim 1, characterized in that the tape in the set (5) of the rollers is subjected to alternating bending. 3. Способ по п.1 или 2, отличающийся тем, что ленту (2) за счет наложения растяжения и изгиба пластически удлиняют в точке (12) набегания и точке (11) схода ленты с отдельных роликов (8a, 8b; 9a, 9b).3. The method according to claim 1 or 2, characterized in that the tape (2) due to the application of tension and bending is plastically lengthened at the point (12) of the run-in and the point (11) of the vanishing of the tape from individual rollers (8a, 8b; 9a, 9b ) 4. Способ по п.3, отличающийся тем, что ленту (2) с короткой длиной (10) натяжения между соответствующими точками (11, 12) схода и набегания на отдельные ролики пропускают через комплект (5) роликов.4.

Устройство для правки холоднокатаной ленты, содержащее комплекты тормозящих и растягивающих роликов, причем предусмотренный между комплектами тормозящих и растягивающих роликов дополнительный комплект (5) роликов содержит растягивающие ролики для создания растяжения и изгиба ленты, отличающееся тем, что комплект (5) роликов содержит четыре растягивающих ролика (8a, 8b; 9a, 9b) для создания растяжения и знакопеременного изгиба ленты.6. A device for straightening a cold-rolled tape containing sets of braking and stretching rollers, wherein the additional set (5) of rollers provided between the sets of braking and stretching rollers contains stretching rollers to create stretching and bending the tape, characterized in that the set (5) of rollers contains four stretching roller (8a, 8b; 9a, 9b) to create tension and alternating bending of the tape. 7. Устройство по п.6, отличающееся тем, что растягивающие ролики комплекта (5) роликов имеют диаметр, отличающийся от диаметра роликов (6, 7) комплектов (3, 30; 4, 40) тормозящих и растягивающих роликов.7. The device according to claim 6, characterized in that the stretching rollers of the set (5) of rollers have a diameter different from the diameter of the rollers (6, 7) of the sets (3, 30; 4, 40) of the braking and stretching rollers. 8. Устройство по п.7, отличающееся тем, что, по меньшей мере, внутренние растягивающие ролики (8а, 9а) комплекта (5) роликов имеют меньший диаметр по сравнению с роликами комплектов (3, 30; 4, 40) тормозящих и растягивающих роликов.8. The device according to claim 7, characterized in that at least the internal tensile rollers (8a, 9a) of the set (5) of rollers have a smaller diameter in comparison with the rollers of the sets (3, 30; 4, 40) of braking and stretching clips.
