Abstract:
An apparatus for separating an upper sheet from a lower sheet, said apparatus comprising:a first roller having an axis of rotation and a sheet engaging surface arranged to frictionally engage said upper sheet, said first roller operatively arranged for rotation in a first rotational direction;a second roller having an axis of rotation arranged in spaced relation to said axis of rotation of said first roller, said second roller having a sheet engaging surface arranged to frictionally engage said lower sheet, said second roller operatively arranged for rotation in a second rotational direction, where said first rotational direction is opposite said second rotational direction; and,drive means for rotating said first and second rollers about their respective axes of rotation to produce different surface speeds at said sheet engaging surfaces of said first and second rollers;whereby said upper and lower sheets are separated by respective frictional engagement with said first and second rollers.
