ABSTRACT:
A sheet supply device of a sheet-fed machine, in particular a printing press, includes a sheet guide element that is adjustable lengthwise and crosswise to a sheet format. Strips that guide the top leading region of a sheet rising on an air cushion extend above a sheet stack downward from a suction head at an incline relative to the surroundings toward a transfer point to the sheet-fed machine. The bands are rolled up onto winding rollers that are acted upon by a restoring force, so that the bands are kept wound or are always kept under tension. In another version, the bands are constructed as elastic bands. At sides of the transfer point, outer bands are mounted on a lateral stack stop and inner bands are mounted on mounts which are adjustable crosswise of the sheets. When the suction head and the lateral stack stops are adjusted, the bands shorten or lengthen in accordance with the adjustment, so that for each format the sheet is guided over its full width.
