Method of injecting a filler in controlled manner into a protective tube for protecting optical fibers, and an installation for implementing the method

摘要

A method of injecting a filler in controlled manner into a protective tube for protecting optical fibers, the method consisting in regulating the delivery rate of the filler being injected as the closed tube advances. In the method, the delivery rate is regulated by detecting the position of the front of the filler contained in the protective tube relative to at least one detection point on the line for advancing the closed protective tube.
