Abstract
PURPOSE: To fusion-cut a plastic film coated on a steel pipe without injuring the steel pipe by a method wherein a plastic-coated steel pipe having the coated film to be fusion-cut is inserted in a looped sheathed heater which is capable of being contracted and expanded in diameter, and extended end parts of the loop of the sheathed heater are pulled to the left and the right respectively.
CONSTITUTION: Brackets 13a are projected from inside surfaces on both sides of a lower part of a support frame 11a at a central part of a frame 11 of a truck 10. A pair of left and right rotatable levers 13 are supported by the brackets 13 through pins. By holding the extended end parts 12a of the loop of the sheathed heater 12 with the tip parts of the rotatable levers 13 and then rotating the levers 13 so as to pull the extended end parts 12a of the heater 12 to the left and the right respectively, the loop is elastically contracted in diameter, whereby the coated plastic film on the steel pipe 1 being conveyed is fusion-cut.
