Abstract

PURPOSE: To twist a longitudinal safely and efficiently by heating the required positions of the longitudinal clamped at plual positions in the longish direction by required means and twisting the clamped portions near the heated part in the direction normal to the longish direction of the longitudinal.
CONSTITUTION: After a longitudinal 5 is fed onto a conveyor 9, a ring 3 is positioned near the conveyor 9 together with a carriage 2 and while the leading end of the longitudinal 5 is being guided by jigs 8, it is placed onto a feed roller 6. In the required positions, the longitudinal 5 is clamped 7 and the carriage 2 is moved integrally with the longitudinal 5 is the direction away from the conveyor 9. Next, when the carriage 2 and longitudinal 5 reach the required position, the carriage 2 is stopped and the longitudinal 5 is clamped 10, then the operator heats the required position of the longitudinal 5 with a fire bending part 13. After heating, it is cooled by cooling water, thence a revolving pinion 4 is driven to rotate the ring 3 in the required direction, thereby giving stress to the longitudinal 5 and twisting and bending the same. After this, while the twisting work is successively made on the other required positions of the longitudinal 5, a bend die is erected occasionally to check the twist condition and whether the longitudinal 5 is twisted in the required state or not is asertained.
