The vacuum deck includes a plurality of vacuum ports arranged in longitudinal rows, each of which is adjacent at least one of the transport belts. A plurality of stop members are located at the downstream end of the vacuum deck. Vacuum at the vacuum ports urge an envelope against the continuously moving belts which transport the envelope to the stop members whereby the envelope is stopped and maintained in a deskewed position.
