FIELD: printing industry. ^ SUBSTANCE: device for paper movement comprises a frame, at least one set of gears, at least one rotary element and an elastic pressing element. The frame comprises the first surface, the second surface and a locating groove. The set of gears is located inside the locating groove. The pressing plank is fixed to the specified second surface of the frame to fix the set of gears in the locating groove and includes at least one extended slot. The set of gears partially passes through the specified slot of the pressing plank. The elastic pressing element is intended to elastically support the set of gears so that the specified set of gears is selectively lifted or lowered depending on the thickness of a paper sheet, and the pressing force between the set of gears and the rotary element is sufficient to move a paper sheet. ^ EFFECT: invention provides a possibility to adjust the pressing force between the set of gears and the rotary element depending on thickness of a paper sheet for its even movement. ^ 8 cl, 6 dwg |
