摘要： An apparatus and a method for manufacturing an optical fiber are provided to save the vertical space by progressing the drawing of the optical fiber with moving the heating portion of the heating element to the top portion of the optical fiber material. An apparatus for manufacturing an optical fiber includes an optical fiber material(2), a heating element(5), a plurality of coils(9). The heating element(5) is a susceptor heated by a high-frequency induction. The plurality of coils(9) generate a high frequency electromagnetic field that is vertically aligned around the susceptor.

摘要： PURPOSE: Provided is a method for drawing an optical fiber, by which optical fiber is drawn stably in a gas seal manner, while varying the outer diameter of the optical fiber preform. CONSTITUTION: The method for drawing an optical fiber comprises the steps of: supplying an optical fiber preform(30) to a drawing furnace(20), while controlling the inner diameter of a seal ring(14U) disposed at the top of the drawing furnace(20); introducing a gas into the drawing furnace(20) so as to spray the gas to the optical fiber preform(30) in the drawing furnace(20), thereby forming a flow running to the outside of the drawing furnace(20) from the gap of the optical fiber preform(30); and heating the front-end part of the optical fiber preform(30) to soften it, and thus to draw the optical fiber.
摘要翻译：目的：提供一种在改变光纤预制棒的外径的同时以气密封方式稳定地拉伸光纤的方法。构成：用于制造光纤的方法包括以下步骤：在控制设置在拉拔炉顶部的密封环（14U）的内径的同时，向拉丝炉（20）供给光纤预制件（30）（20）; 将引入气体导入到所述拉拔炉（20）内以将所述气体喷射到所述拉拔炉（20）中的所述光纤预制件（30），从而形成从所述间隙向所述拉拔炉（20）的外部流动的流动的光纤预制件（30）; 并加热光纤预制件（30）的前端部分使其软化，从而拉制光纤。

摘要： A winding device of a wire body having a simple arrangement and a winding method wherein the cut end wire at the end of winding is contained in an annular guide arranged movably on one end part side and does not project from the annular guide. The annular guide (20b) is arranged such that it can cover one flange part of the wire body winding bobbin (3) and provided with a cut (24) for guiding the wire body, wherein the diameter of the inner circumferential surface (25) is enlarged sequentially toward the direction away from the bobbin. The annular guide (20b) may be shaped to have a stop part (26) for preventing the wire body from projecting to the outside of the bobbin. The annular guide (20b) is arranged on the flange part (3a) movably in the axial direction of the bobbin or the annular guide (20b) is constituted of a plurality of parts which are moved to be arranged annularly on the flange part (3a).
