Problems solved by technology

Therefore, only the fixed part of the spinning part wears due to the running of the spinning part in contact with the yarn, which may cause problems such as breakage of the spinning part, and may shorten the life of the spinning part.
Moreover, when problems such as breakage of the spinning part occur due to wear of the spinning part, the spinning machine needs to be stopped in order to replace the spinning part, which affects the production efficiency of the package.

Abstract

The present invention provides a slack eliminating device which improves a life of a yarn hooking member (52) with respect to wearing away caused by traveling of a yarn by changing a position at which a yarn unwound and traveling from a slack eliminating roller (39) makes contact with a yarn hooking member (52). The outer periphery (70) on the top side end part of the downstream side of the slack eliminating roller is formed to be elliptical seen from the axial direction of the slack eliminating roller. The yarn hooking member (52) is expressed by using solid line when placing at long diameter part, and expressed by using two-dot chain line when placing at short diameter part. when the yarn hooking member (52) rotates with respect to the slack eliminating roller (39), the position of the yarn hooking member (52) contacting with the yarn that is unwound from the slack eliminating roller (39) changes in a width D.

Description

technical field [0001] The invention relates to a yarn slack eliminating device, in particular to a yarn slack eliminating device in a spinning machine. Background technique [0002] Conventionally, there is a spinning machine in which a yarn is spun by a spinning device, and the spun yarn is taken up by a winding device to manufacture a package. This spinning machine includes a yarn slack eliminating device for adjusting the winding tension of the yarn before the yarn spun by the spinning device is wound by the winding device. This yarn slack removing device includes: a slack removing roller that is driven to rotate and winds the yarn around the outer peripheral surface for accumulation; The yarn that is unwound from the slack eliminating roller and travels is guided to the downstream yarn guide while contacting; the downstream yarn guide is arranged on the downstream side of the slack eliminating roller, and guides the yarn to the winding device ( See, for example, Paten...
