Wire feeding device

Abstract

The present invention provides a yarn feeding device that suppresses vibration of the driven roller during yarn travel without impairing the function of pressing the driven roller against the drive roller with appropriate contact pressure and the function of switching the posture of the arm during yarn loading or maintenance. The driven roller support mechanism (20) supporting the driven roller (12) includes: an arm (30); a support body (50) that supports the arm (30) to be rotatable; a rod (70) that switches the posture of the arm (30); a force-applying member (80) that applies force to the arm (30) and switches the posture from the release posture (PY3) to the pressing posture (PX1) while switching the posture of the arm (30) from the separation posture (PB3) to the contact posture (PA1); and a vibration damping member (90) having a contact portion (95). When the arm (30) is switched to the contact position (PA1), the force-applying member (80) switched to the pressing position (PX1) presses the contact part (95) of the vibration damping member (90) against the contacted part (35) of the arm (30).
