System for rotationally slaving an optical fiber feeding and dispensing device in a cabling line

Abstract From the Canadian patent

In an optical fiber cabling line where a ring having helical grooves is drawn at a constant translational speed by a main motor,there is provided a system for slaving a rotational speed of an optical fiber feeding and dispensing device driven by motor means to a number of ring groove pitches per second in order to compensate for groove pitch fluctuations resulting from the ring production process. The system comprises roller and cam means coupled to the ring and to the feeding and dispensing device for detecting a difference between the rotational speed and the number of pitches per second thereby converting the speed difference into a voltage variation. The motor means comprises a …
