Abstract
"Anti-wander" web-transport arrangements wherein web-means are intermittently advanced, while being monitored for misalignment along the transport-path, and also being automatically urged back into proper alignment along this path. Preferably, this is done with left and right roll means, one of which is selectively urged more tightly against the web to impart superior advance-thrust and so urge the web back into proper alignment.
