Claims

[Scope of Claim for Utility Model Registration] An open-end spinning machine in which a bobbin held by a cradle lever is brought into contact with a take-up roller, and thread is wound around the outer circumference of the bobbin by the rotation of the take-up roller to form a package cage. An arm 8 is mounted approximately in the center of the cradle lever support shaft 2 supported on the upper part of the fixed bracket.
A main guide pin 11 is pivotally supported between a support shaft 10 supported below the bracket and a shaft 9 supported at the tip of the arm 8, and a main spring is attached to the main guide pin 11. 12, and a long hole that is perpendicular to the straight line B-B connecting the cradle lever support shaft 2 and the auxiliary spring support shaft 13 when the package diameter reaches a predetermined diameter in order to tightly wind the thread. 14 is provided in the arm 18 at the bottom of the proximal end of the cradle lever 3, and the elongated hole 1
An open-end spinning machine characterized in that an auxiliary guide pin 16 is used to pivot between a stud 15 that is fitted into a stud 15 and an auxiliary spring support shaft 13, and an auxiliary spring 17 is fitted to the auxiliary guide pin 16. Thread winding device.
