Abstract

PURPOSE:To install a vibration absorbing exhaust pipe safely by contracting a diameter of the edge of a net component covering the external circumference of a bellows pipe with a special tool. CONSTITUTION:Although the external circumference of a vibration absorbing bellows pipe 5 to be applied to a part of an exhaust pipe for an internal combustion engine is covered by a net cylinder 6, the edge is formed of a contracted diameter in conformity with a contracted diameter edge 5a of the bellows pipe 5. Then, if the net cylinder 6 is supported between an upper die 10 and a lower die 13 and a net cylinder 7 is inserted forcibly into a lower die 14 having a groove 16 for diameter contraction a diameter of the lower half part of the net cylinder 7 is contracted in confirmity with a shape of a contracted diameter part 5a. Then, an upper die 18 having a groove 20 for the diameter contraction is lowered, a diameter of the upper half part of the net cylinder 6 whose lower half part is made into an oval through the diameter contraction is contracted and the edge 7 of the net cylinder 6 can be touched closely to the contracted diameter edge 5a. As this is made with such forming die a manual application becomes unnecessary and a hand is not injured.
