    摘要: "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.

    摘要: Servo methods and apparatus whereby unit-record documents are transported past a process-station according to one of several "velocity-profiles", depending upon document type and/or condition, the methods involving: using a microprocessor whereby the documents are transported past one or more process-stations according to one of several "velocity-profiles", depending upon document type and/or condition.The methods involve arranging the microprocessor to store at least two different velocity-profiles and to store prescribed characteristics of each contemplated document and deploying passage-sensors along the path in prescribed spaced-relation with the process stations, whereby a given velocity-profile is automatically selected, in real time, and on-the-fly, by the microprocessor for each said document transported.
