Pneumatic sheet transport and alignment mechanism

摘要

A pneumatic sheet transport and alignment mechanism is disclosed utilizing the orientation of the air jets in the pneumatic transport to cause the sheet being transported to be moved laterally to engage an edge guide such that the sheet is properly aligned for subsequent operations upon exiting from the transport and alignment mechanism. Additionally a technique is disclosed which allows the sheet to be progressively engaged with the edge guide or reference edge such that the trailing corner of the sheet as it progresses through the transport is engaged with the reference edge prior to the leading corner thereby avoiding jams and retarded sheets.
