ABSTRACT:
A method and system for correcting the skew in mail-related items, which are caused to move by a driving mechanism in the mailing machine. The driving mechanism comprises at least two driving belts to drive the mail-related items by friction. A plurality of openings are provided on the driving belts so that air pressure can be applied to the mail-related items in order to change the friction between different driving belts and the mail-related items. The air pressure can be positive or negative and it can be applied on the left or right side, or on both sides but with different pressures.
