Abstract

PURPOSE:To obtain a wiry material, having excellent productivity and useful as optical fibers, etc., at a low cost, by sampling an initially wound part of the wiry material in a drawing machine by a specific means to carry out a qualification test and winding the wiry material around a drum. CONSTITUTION:An initially wound part (10a) of a wiry material 10 drawn and formed by a drawing machine is passed by a drum 18 while being fed with a pinch roll means 24 consisting of a driving roll (24A) and driven roll (24B) at a constant speed through a take-off machine 12, a guide means 14 and a tension controlling means 16, then pulled by an air gun 26 and sampled. The resultant sample is subsequently inspected (e.g. outside diameter and core diameter of an optical fiber) by an inspecting means to confirm desired quality. The initial winding part (10a) is then moved from a position (A) to (B) by an air cylinder 28 of the air gun 26. The moved wiry material 10 is subsequently caught by a capturing pawl 22, fixed to the drum 18 and wound by normal operation.
