摘要

PROBLEM TO BE SOLVED: To provide an oil applying guide device capable of stably and uniformly applying an oil in the step to apply an oil to a synthetic fiber yarn and provide an oil application method.;SOLUTION: The oil applying guide device is composed of a yarn contacting face (a) to apply an oil by contacting with a moving yarn, a yarn introducing part (b) composed of a straight wall face having a depth L of 2-15 mm for introducing a yarn to the yarn contacting face (a), an oil reservoir groove (c) extending from the yarn contacting face (a) to the straight wall face of the yarn introducing part (b) in a form crossing the moving yarn, an oil supplying face (d) formed to drop and supply the oil to the yarn contacting face (a) and crossing the yarn contacting face (a) at a cross angle θ1 of ≤20°, and an ejection hole (e) opened on the oil supplying face (d). An upper face (f) of the oil applying guide has a shape inclined downward in the moving direction of the yarn and the width W of the opening (g) is ≤3 mm.;COPYRIGHT: (C)2008,JPO&INPIT
