Abstract
PURPOSE: To efficiently perform a cylinder work with high precision preventing any torsional deformation in a direction of width in a bending work by controlling a breadthwise position of a material to be worked utilizing the constraining members in the bending work of the material to be worked using a plurality of rolls.
CONSTITUTION: A position of a constraining member 6 is adjusted by a slider 8 to conform with a width of a material to be worked 1. The material to be worked 1 processed end-bending beforehand is inserted from a position between the opposing faces of the members 6 into rolls 3, 2, 4 and the bending work is performed with a forced feeding of the material by the rotation of rolls 3, 2, 4. In this bending process, a cylinder having the prescribed curvature is obtained by properly descending the upper roll 3 and by repeating forwards and backwards rotations of lower rolls 2, 4. In this case, the material 1 always passes through between the opposing faces of the members 6 so that any torsion or the like is not occurred. By this method, a working with high precision is attained easily, and also, operational efficiency is improved.
