Manufacturing assembly and process for the production of an extruded tube provided with at least one optical fibre

摘要

The present invention relates to a method of manufacture of an extruded tube 22 provided with at least one optical fiber 21, consisting of extruding the tube around the fibers, to pull the tube and the fibers by means of a capstan - tractor 10 by providing an elastic elongation of the tube, the release of the tube to the output of the capstan - tractor, resulting in a supplementary fibers, characterized in that it is desired to measure the speed of movement of the fibers or upstream of the extrusion operation and the speed of movement of the tube downstream of the capstan - tractor, and then compares the ratio of these two speeds to a predetermined ratio, the result of this comparison being used to control the speed of the capstan - tractor in order to obtain a supplementary fibers constant. & br / & it also relates to an installation enabling the îoeuvre of the process. & br / application to the manufacture of optical fiber cables. & br / (see appended drawing in bopi) & br / & & br /
