发明名称 METHOD AND DEVICE FOR SOLID TWISTING OF FLEX TUBE UNIT
摘要 PROBLEM TO BE SOLVED: To provide a method and device for solid twisting of a flex tube unit. SOLUTION: The solid twisting is a combination of a buffering process and twisting processes, and since the twisting process is performed while a flex tube is hot, the flex tubes ate fitted collectively with no extra binder. An optical fiber and/or a wire is fed to an extruder, and the flex tube is formed around individual or a group of optical fibers and/or wires. A central component can be fed. for passage, to a central part of the extruder. The flex tube is, while being cooled, formed in a spiral around the central component by a revolving/ pulling device such as a caterpillar or solid-twisted by an SZ method, or, with no central component present, the flex tube itself is solid-twisted.
