Turnover module

摘要

A turnover module for turning over envelopes comprises a plurality of pulleys and disposed thereabout a driven endless belt in the general shape of a flattened figure '8'. The belt includes a crossover region and a first and a second reach extending therethrough. The reaches contact one another resiliently along length portions thereof while crossing over and twisting about one another. Envelopes are received in a first orientation at an entry end of the reaches; nipped between the reaches; transported thereby through the crossover region while being turned over by virtue of the twist of the reaches about one another; and, delivered from the turnover module in a second orientation.
