Title:
MANUFACTURING METHOD OF SHAPE TUBE
Document Type and Number:
Japanese Patent JPS5521286
Kind Code:
A
Abstract:

PURPOSE: The shape tube rotates circumferentially, at the same time, it removes axially. The forming material layer is formed on the core type which is cylindrically maintained. The shape tube is manufactured with good productivity by changing before the forming material layer hardens.

CONSTITUTION: The adhesives are coated on the outer surface of the band material provided on the mandrel 1. The band material 2 is spirally coiled to form the core type 5. This core type 5 is circumferentially rotated at the same time, and it is removed to the top direction. Next, the forming material layer consists of inner surface layer 7, intermediate layer 9 and surface layer 10 on this core type 5. After the forming material layer is formed, it is broken away from mandrel 1, before the forming material layer hardens. Next, this forming material layer is intorduced to the deformed device 13 which provides the 2nd cylinder 133. The strut 134 is mounted to the hollow direction on the inner surface of the 1st cylinder 132. After the forming material layer is deformed with the roller 135 provided between struds 134, it is hardened through the hardening reactor 14.
