Embodiment Construction

[0041] exist Figure 1 to Figure 12 Embodiments and variations thereof are shown. In the examples, the winding of the false-twisted yarn in the false-twisting machine was taken as an example, but it is not limited thereto. In addition, although the yarn winding method is segmental precision winding, it may be only precision winding or other yarn winding methods. In these figures, 2 is a bobbin, on which the yarn is wound (coiled) to form a bobbin 4, and the bobbin 2 is freely rotatably supported by a hanger 6 that can swing freely, and the contact roller 8 serves as The rollers are driven to rotate the bobbins 4 . Since the slippage between the contact roller 8 and the package 4 is neglected, the peripheral speed of the contact roller 8 and the winding speed of the package 4 have the same value u. Alternatively, the package 4 may be rotated by a drive shaft provided on the hanger 6 side.

Abstract

Control the oblique winding angle curve of the central part when the bobbin is wound by segmental precision winding, etc., so that the trajectory of the yarn path on the rotary part is constant, and the curve is wound with a specified oblique winding angle to obtain the desired Desired number of windings.

Description

technical field [0001] The present invention relates to a yarn winding method and device thereof. Background technique [0002] Patent Document 1: Japanese Patent Publication No. 2001-516319 (USP6008613) [0003] In winding of the yarn, the traverse guide is reciprocated relative to the bobbin and the yarn is guided by the traverse guide. The angle of the yarn relative to the circumference of the bobbin is called the oblique winding angle, and the oblique winding angle is controlled by controlling the speed of the traversing yarn guide. Conventionally, a traverse guide generally controls a plurality of bobbins collectively by means of a cam or the like, but Patent Document 1 discloses a technique in which the traverse guide is independently controlled by a stepping motor. [0004] It is also known that the skew angle affects the properties of the wound package. For example, when the skew angle is large, the doffing is reduced, and on the contrary, the density of the packa...
