Abstract: An improved deskewing device for a postage meter mailing machine comprising a support mounted over an upper surface of the mailing machine feed deck. A first feed roller is rotatably mounted on the support upstream from the postage meter with the axis of the first feed roller disposed at an angle within the range of 5 to 30 degrees to the registration guide and spaced laterally from the feed deck registration guide at approximately 0.75 inches. A drive rotates the first feed roller. Mounted in the feed deck is semispherical member directly below the first feed roller. A drag is mounted to the support upstream from the postage meter for encountering the envelope and applying thereto a drag force parallel to the registration guide and counter directional to the envelope traversing direction, the drag being spaced laterally from the registration guide approximately 3.0 inches therefrom and upstream from the first feed roller approximately 0 to 0.6 inches therefrom.
