Abstract
The invention relates to a sheet feeding station for a magazine in which a plurality of individual sheets are located one against another, with a pneumatic pick-up roller rotatably mounted adjacent to the magazine and at that end of the magazine from which the sheets are destined to leave the magazine. The invention is characterized in that the roller is stationary in a precisely defined rest position at the start of a sheet-feeding feeding operation and remains in this rest position until it is sensed that a sheet is held against it by air pressure, the roller then rotating to feed the sheet so held, and continuing to rotate until the sheet-feeding operation has been completed.
