Abstract

PURPOSE: To exactly keep the cutting length, when an intermediate product having sectional shapes gradually varying in the longitudinal direction is formed by two roller die devices, by determining the cutting length with the controller of the roller die devices.
CONSTITUTION: A horizontal roller die device 2 is installed on the upstream side of the traveling line of the material 1 to be worked, and a vertical roller die device 3 perpendicularly arranged to the roller die device 2 is installed on the downstream side; an intermediate product 25 having sectional shapes periodically varying in the longitudinal direction is formed by said two roller die devices 2, 3. The measuring instruments 26, 27 for measuring the position and gap of rollers of each of roller die devices 2, 3 are installed, and a material's traveling length measuring instrument 7 is installed; measured values of the these instruments 26, 27, 7 are inputted to the controller 15. The controller 15 operates the aimed values of the position and gap of each of roller die devices 2, 3 from the output signal of the instrument 7 and the conditions preset in the controller itself. The controller 15 produces a command signal as a result of this operation, in order to suitably control the position and gap of rollers and to give a constant sectional deformation to the intermediate product 25 in the longitudinal direction; besides, the controller 15 produces a command to cut the product 25 at a prescribed position by the cutting machine 10: hereby, the intermediate product 25 in a prescribed shape is manufactured in high yields.
