Abstract
The 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 rationally 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.
