PURPOSE:To facilitate the yarn ending operation, by holding a wax supporting shaft provided between a spinning unit and a taking out roller of a spun yarn rotatably about a position at a distance from the shaft line. CONSTITUTION:In an apparatus for bringing a yarn (Y) spun from a yarn guide 3 in an open end spinning frame is brought into contact and waxed with a wax 23, if necessary passing the yarn (Y) through a traverse guide 9 while held between a taking out roller 5 and top roller 8, and taking out the yarn (Y), a supporting shaft 17 for supporting the wax 23 is supported rotatably about a shaft (O) at a given distance from the shaft line (L) of the shaft 17. Concretely, the supporting shaft 17 is held by a disk-like turning bracket 14, and the vicinity of the end of the turning bracket 13 is pivoted by a spinning pin 13. Thus, the wax supporting shaft 17 is turned from a yarn path (to a position indicated by an alternate long and two short dashes line), and the yarn ending operation is facilitated by a large space formed near the yarn path.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a yarn wacking device for an open-end spinning machine.

Generally, in textile machines such as open-end spinning machines, yarn winding machines, and yarn wrapping machines, various types of wagging devices are used that apply wax to yarns to make them smooth. As an example of this, as shown in Japanese Utility Model Application Publication No. 52-158138]-

It has been proposed that when the special waggishing device for yarn splicing gets in the way, the wax and cover are flipped upward together with a guide pin and held in a retracted position.

However, in the above-mentioned waxing device, the wax and cover are moved upward, that is, along the thread, when the waxing device is reversed to the retracted position, so in order to pull out the thread from the gap between the wax and the cover, the wax must be separated from the cover. It is necessary to pull the yarn to the side of the cover to remove it from the gap, and therefore, the reversing operation is troublesome and becomes an obstacle to the yarn splicing operation, which requires speed.

An object of the present invention is to support a wax support shaft so as to be substantially perpendicular to the traveling path of the yarn, and to be able to tilt it toward and away from the yarn in this orthogonal state, and to support the tilting center of the support shaft in the same manner. The yarn is deviated a certain distance from the central axis of the shaft to the side corresponding to the yarn, and then the yarn is fitted into the support shaft C. ni;!f,<

Since it is formed on the guide plate 21, it is possible to easily switch the IT waxing device, which operates the machine base, from the operating position to the retracted position and vice versa with a single touch.

Furthermore, in the embodiment of the present invention, the tilting center 0 of the support shaft 17 is shifted in the direction corresponding to the traverse width W' of the yarn Y, so that the guide plate 21 is shifted during the position switching operation of the armpit/puffer device. By reducing the amplitude in the front-rear direction, fluctuations in tension on the yarn Y can be reduced, and deterioration in yarn quality can be prevented.

Note that the present invention can also be embodied in the following embodiments.

(1) In the above embodiment, the straight line e parallel to the support shaft 17 passing through the tilting center O of the support shaft 17 is the traverse width W' of the yarn Y.
Eccentric pressure 1) was set at 6 points passing through the outer end 1゛ of
