Fiber feeding device

Abstract

The invention relates to a feeding device which minimizes the vibration of the driven roller while the yarn is running without reducing the function of pressing the driven roller against the drive shaft with appropriate contact pressure and the function of changing the position of the lever during yarn threading or maintenance. The driven roller support mechanism 20 is constructed to support the driven roller 12 comprising: lever 30; support unit 50 supporting the rotation of lever 30; lever 70 constructed to change the position of lever 30; shifting unit 80 constructed to provide force to lever 30 and is converted from the release position PY3 to the pressing position PX1 with the position of lever 30 being converted from the detached position PB3 to the contact position PA1; and the 90 anti-vibration unit has a contact area of ​​95. In the state where the 30 lever is switched to contact position PA1, the 80 displacement unit is switched to pressing position PX1, pressing the 95 contact area of ​​the 90 anti-vibration unit against the 35 contact area of ​​the 30 lever.
