Document turning station

摘要

A document handling device that is adapted to turn a document such as a letter or other flat mail piece through an angle of substantially 90 degrees in its own plane by means of a plurality of pairs of feed rollers, the latter being respectively driven at different effective speeds which are proportional to the respective distances of said feed roller pairs from a predetermined axis located adjacent the lower leading corner of said document. The geometry of the system is such that the lower edge of the document before and after being turned is adapted to move along one substantially horizontal planar surface. Provision is made for enabling at least some of said feed roller pairs to feed a document without turning the latter through said 90 degree angle.
