Abstract
A vibration friction feed wheel mechanism for feeding thread to a thread processing machine having intermittent thread requirement. The feed wheel mechanism including a high friction contact surface, a thread guide level for lifting thread off of the feed wheel and a vibration generating arrangement for applying a vibrational movement to the thread. The vibration of the thread ensures that the thread lifts-off from the contact surface of the friction feed wheel by reducing the coefficient of friction between the thread and the high friction contact surface of the friction wheel.
