Abstract

PURPOSE:To cool a heated drive member within a short time, by providing not only an air feed pipeline for cooling the drive member but also a discharge means for discharging the air injected from said air feed pipeline. CONSTITUTION:When a switch 22 is turned ON, signal is inputted to a current supply part 18 and an air feed pump 21 from a current supply control part 19 and a current is supplied to the first drive member 11 to heat the same and the air feed pump 21 is operated for a predetermined time. When the drive member 11 receives the supply of a current to be heated, a curving part 6 is curved upwardly. When a switch 23 is turned ON, the second drive member 12 receives the supply of a current to be heated and the curving part 6 is curved downwardly. At the time of this curving operation, the air feed pump 21 is operated for a predetermined time to inject compressed air to the curving part 6 through an air feed tube 26.
