Abstract

PROBLEM TO BE SOLVED: To reduce operator's labor by allowing an operator to easily execute work to thermally weld the sheet end parts of a first sheet and a second sheet which are spread over a first body surfacing upward and a second body surface erected from the first body surface. SOLUTION: Under a state that the first sheet 2 and the second sheet 12 are respectively spread over the first body surface 1A facing upward and the second body surface 1B erected from first body surface 1A, a travel machine body 3 capable of travelling on the first sheet 2 is provided. An insertable heated air ejection nozzle 4 is provided between the lower end part 12A of the second sheet 12 and the end part 2A of the first sheet 2 overlaid on the lower end part 12A. Heated air can be ejected between the lower end part 12A of the second sheet 12 and the end part 2A of the first sheet 2 as the travel machine body 3 travels. The travel machine body 3 is provided with a pressing roller 5 which thermally welds by pressing the lower end part 12A of the second sheet 12 and the end part 2A of the first sheet 2 between which heated air is ejected as the travel machine body 3 travels.

[Operation] The first sheet and the second sheet are separately laid on the first frame surface facing upward and the second frame surface rising from the first frame surface, and overlap the first frame surface side. The hot air jet nozzle is inserted between the lower end of the second sheet folded as described above and the end of the first sheet superimposed on the lower end of the second sheet from above, and as the traveling body travels, Inject hot air from

[0012] Then, the hot air is injected between the second
The lower end of the sheet and the end of the first sheet are pressed by a pressing roller as the traveling body travels, and are thermally fused.

[0013] Since the heat fusion is performed in this manner, the operation is less time-consuming as compared with the case where the operator performs the heat fusion with a hand-operated heat fusion machine.

[Effect] Therefore, the first body surface facing upward,
The operator can easily perform the operation of thermally fusing the end portions of the first sheet and the second sheet separately laid on the second skeleton surface rising from the first skeleton surface, and Labor was reduced.
