Abstract
A web threading system for threading a web through a dryer and an optional chill roll stand. The web attaches to a lock up roll threading bar. A lock up roll threading bar is carried between a pair of parallel dryer chains to lead and thread the web through the dryer environment, and through and about optional chill rolls in a chill stand. A locking mechanism is provided for the lock up roll threading bar to engage the web for ready attachment or disengagement of the web from the lock up roll threading bar before and after the threading process.
