METHOD FOR STRAIGHTENING, MAINLY, THIN NARROW STRIPS AND BELTS Russian patent published in 1998 - IPC

FIELD: plastic metal working, namely, straightening strips and belts. SUBSTANCE: method comprises steps of reducing strip in cone working rolls whose axes cross at side of small bases of their cones and whose cone generatrices are mutually parallel in reduction zone; checking curvature of strip at roll outlet after first pass, guiding strip to rolls in next pass by center of its edge curvature to side opposite relative to crossing point of roll axes. At reducing process tail end of strip is tensioned due to applying braking effort. Mathematical relations for determining reduction value Δh and tension T are given in description of invention. EFFECT: enhanced efficiency. 2 cl, 1 tbl, 2 dwg
