PCT No. PCT/DE95/00274 Sec. 371 Date Sep. 16, 1996 Sec. 102(e) Date Sep. 16, 1996 PCT Filed Mar. 2, 1995 PCT Pub. No. WO95/25057 PCT Pub. Date Sep. 21, 1995The invention relates to a sheet-extracting device with a cassette for receiving a stack of sheets, and to a method of controlling the pressing force of the stack of sheets against the extracting device. The latter has extracting rollers (16) which are arranged on a floating shaft (34). For its part, the floating shaft (34) is centrally connected in a rotationally fixed manner to a drive shaft (18) passing through it. The drive shaft (18) is mounted, by one end (20), in a frame-mounted bearing (21) and, by its other end (62), in a displaceable bearing (64). Acting on the bearing (64) is a force sensor (70, 74, 76) which is intended for determining the pressing force of the stack of sheets (12) against the extracting rollers (16). The pressing force is controlled such that it always moves within a narrow middle range between a minimum and a maximum possible value.
