Title: Optical fiber drawing method and its device
IPC: C03B37/07
Filed: 1992-03-27
Abstract: PURPOSE:To exactly regulate stickiness and to prevent the fluctuation in outside diameter size by drawing an optical fiber while controlling the output of a resin crosslinking device in accordance with the detected value of the degree of sticking on the surface of the optical fiber. CONSTITUTION:The molten front end part of an optical fiber base material 3 heated by a heater 2 in a heating furnace 1 is drawn out of an outlet 1a and is passed through a high-molecular resin applying device 4 and the resin crosslinking device 5, by which the resin coated optical fiber 6 is obtd. This fiber 6 is then clamped in take-off units 7, 8 of a belt lapping type. A detector 11 for the stickiness on the surface of the fiber 6 consisting of a roller 13 applied downward with specified load and a roller 14 mounted with a rotating stress sensor is arranged between the units 7 and 8. The fiber 6 is then transferred between the rollers 13 and 14 and the output signal of the rotating stress sensor is inputted to the detector 11. While the controller which outputs the output control signal of the device 5 by comparing the above output signal with a target value is operated, the fiber is passed along a dancer 9 and is taken up by a take-up device 10. The optical fiber is thus drawn.

Filed: 1985-05-11
Abstract: PURPOSE:To correct a positioning error, and to detect a defect with a high accuracy by setting a partial area extending over the whole area in an inspecting image pattern, and detecting a compared position at every partial area. CONSTITUTION:A partial area A containing many inspecting image picture elements is set in an inspecting image pattern P2. On the other hand, an expanded area B containing the partial area A and also containing many reference image picture elements, which is wider than said area is set in a reference image pattern P1, and in its area, a reference image pattern reference area C11 of the same size as the partial area A is read out by shifting one picture element each.
