Abstract

DC60, the outer surface of the core tube 31 has been pressed for forming a 313 protrusion on the inner surface of the core pipe 31 and the tubing 32 has been wound in a spiral loop around the outer part of the Core tube 31 After that, core tube 31 and core tube 32 have been bent together. As a result, the outer surface of the duct 32 is in contact with the outer surface of the core tube 31 without any gap between the center of the bend (D) and the surface. The outside of the wrapper (32) is fixed to the outer surface of the core tube (31) by the binder (33) at the center of bend (D) of the surface CC bend. The outside of the core tube 31 has been pressed for forming a 313 overhang on the inner surface of the core tube 31 and the core tube 32 has been wound in a spiral loop around the outer loop part of the core tube 31. After that, the core pipe 31 and the wrapping pipe 32 were selected together. As a result, the outer surface of the duct 32 is in contact with the outer surface of the core tube 31 without any gap between the center of the bend (D) and the surface. The outside of the wrapper (32) is fixed to the outer surface of the core tube (31) by the binder (33) at the center of bend (D) of the CC bend.

Claims (3)
