    • A device for continuous and individual feeding of sheets from a stack to a depositon site comprises gripping members (15) for grasping and hoding the sheets, and a movement device for displacing the gripping members (15) between the stack and the deposition site. The movement device displays two arms (12, 13), which are provided with the gripping members (15). The arms (12, 13) are pivotal about a vertical pivot axis (14) and are movable therealong in the verical direction to positions (33) for both depositing and picking a sheet. Further, the one arm (12, 13) may be pivoted past the other (12, 13). A feeder station for feeding in accordance with the foregoing includes at least one sheet stack, a deposition site and a feeder device. The stack and the deposition site are disposed on a common arc of a circle, and the feeder device has a pivotal arm (12, 13) which is provided with gripping members (15). A method of feeding in accordance with the foregoing in which use is made of a movement device as disclosed above. One gripping member (15) discharges a sheet when the second gripping member grasps a sheet on the stack. Thereafter, the gripping members (15) are lifted and pivoted so that they pass each other, whereupon they are both lowered, so that the method may be repeated.
