Abstract
In a system and method for feeding sheets from a stack, a support arrangement is provided having a plurality of rows of rollers mounted on support levers to support the stack above a first carrier. The rollers are lowered so that a lowermost sheet of the stack contacts the first carrier which is driven to cyclically accelerate the lowermost sheet in a direction perpendicular to the rows so that the sheet achieves a linear velocity. A second carrier is driven at a constant speed to transport the sheet away from the first carrier at the linear velocity. Each row of rollers is sequentially raised when a trailing edge of the sheet has moved beyond that particular row.
