An apparatus for improving sheet feeding in a direction of movement to a process
station, including: a contact surface having ribs spaced along contact surface
in the direction of movement, apertures being defined in the space between each
rib; a blower; and an air plenum for supplying a vacuum generated by the blower
to the contact surface so that when an leading edge of the sheet passes by the
contact surface the vacuum pulls the leading edge of the sheet towards contact surface.
