Abstract
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.
