Abstract
An apparatus for separating an upper sheet from a lower sheet comprising a first roller having an axis of rotation and a sheet engaging surface arranged to frictionally engage the upper sheet, a second roller having an axis of rotation arranged in spaced relation to the axis of rotation of the first roller, the second roller having a sheet engaging surface arranged to frictionally engage the lower sheet, and, drive means for rotating the first and second rollers about their respective axes of rotation to produce different surface speeds at the sheet engaging surfaces of the first and second rollers, whereby the upper and lower sheets are separated into a non-coincident configuration by respective frictional engagement with the first and second rollers. The invention also comprises a method for separating the aforementioned upper and lower sheets.
