Abstract
The thread winding machine comprises a rotatable chuck having a thread catching device adjacent to a location for a bobbin tube upon the chuck. A thread guide engages the thread and moves it axially of the chuck into the catching device at a first speed and then onto the bobbin tube location at a second, higher speed. An overwound thread reserve or transfer tail is formed by moving the thread guide against a resilient damper, causing it to stop and rebound.
