METHOD AND APPARATUS FOR IMPROVING SYNCHRONIZATION IN A DOCUMENT INSERTING SYSTEM

摘要

A method and apparatus for improving the timing between the releasing o f documents from enclosure feeders and the arrival of pusher fingers fixedly attached to a conveyer belt in a gathering section of an inserting machine. As the conveyer belt begins to wear and stretch after being used for a long period of time, the timing between the releasing of documents and the arrival of pushe r fingers may no longer be appropriate. By using two sensors placed, preferabl y, at the two ends of the gathering section to measure the timing of the arrival o f the pusher fingers at the sensors, the stretch of the chain can be determined an d the delay of the arrival of a pusher finger at each enclosure feeder can be calculated. Adjustment to the releasing timing at each enclosure feeder can be made accordingly.
