Abstract

PURPOSE:To get rid of breakage of the core mold and prevent growing of vibration of the core mold, by lowering the height of the axis of the core mold following the hardening device of the composite tube manufacturing apparatus than the height of the axis of the core mold ranging from the root of the core mold to the hardening device. CONSTITUTION:The core mold 3 is formed by winding the belt like thick sheet of paper 2 applied with the adhesive spirally and partly being overlapped on the mandrel 1. The core mold 3 is wound twistedly by the endless belt 4 and moved to the direction of its tip, being driven by rotation of the belt. After the forming material 6 of which the reinforcing material of the glass fiber etc. is impregnated with thermosetting resin is wound on the core mold 3 at the material forming part 5, the forming material 6 is hardened by the hardening device 10. In such a composite tube manufacturing apparatus the height of the core mold 3 following the hardening device 10 is made lowered than the height of the core mold 3 ranging from the root of the core mold 3 to the hardening device.
