Abstract:
A method for preparing mailpieces, the method comprising the steps of:a) providing an inserter system comprising a chassis for assembling mailpieces, the chassis operating cyclically with successive accumulations advancing at the end of each cycle, and a document feeder for feeding accumulations of documents to the chassis, the accumulations containing varying numbers of documents;b) operating the document feeder at a fixed linear speed, whereby accumulations are available for input to the chassis at varying intervals substantially depending upon the number of documents in corresponding accumulations, so that there is a possibility that no accumulation will be available for particular cycles of the chassis;c) initially operating the chassis at a selected speed;d) periodically determining a measure of the fraction of the cycles for which one of the accumulations is available and comparing the measure to a selected value; ande) if the comparison indicates that the fraction is too low, decreasing the chassis speed; andf) if the comparison indicates that the fraction is too high, increasing the chassis speed.
