IN-LINE ROTARY INSERTER

摘要

A turnover module for an in-line rotary inserter having an envelope handling system for processing insert- filled envelopes. The turnover module includes a belt and pulley system having at least four pulleys disposed substantially in a common vertical plane. The pulleys are grouped in pairs with each pair being disposed proximally to and substantially above one another. The pulley system includes an endless flat belt disposed about the pulleys in a resiliently tensioned manner in the shape of a flattened figure 'eight' having a cross- over portion. The cross-over portion including two mutually contacting length portions of the flat belt twisted about one another by an angle of substantially one hundred and eighty degrees. Further, the cross-over portion is operative in nipping between the length portions of an envelope delivered to the turnover module and transporting the envelope therethrough while turning the envelope over by substantially 180 degrees.
