APPARATUS FOR CONTINUOUS STRAIGHTENING OF STEEL STRIPS BY BENDING THEM WITH TENSION Russian patent published in 1995 - IPC

FIELD: metal pressure forming. SUBSTANCE: apparatus has working rollers with a small diameter d and bridle rollers with a large diameter. The apparatus includes three sections of the bridle rollers and four sections of working rollers, having a length of a barrel l=(1.6-1.8)d. Each working roller is mounted between two supporting props with an axial pitch value t= (1.25-1.50)l by a staggered fashion relative to the working rollers of an adjacent section. The sections are arranged in pairs and symmetrically relative to a mean bridle roller, rigidly connected with two sections, spaced from it by a maximum distance, mounted under these sections and capable to be moved in a vertical plane. Paired rollers of each section are arranged one relative to another with vertical spacing, equal to (0.85-1.50)d and with a horizontal spacing equal to (2.3-2.5)d. The terminal bridle rollers are mounted under the terminal working rollers. EFFECT: lowered cost for shaping strip due to enhanced structure of the apparatus. 1 cl, 2 dwg
