SUBSTANCE: set of invention relates to sheet stacker and method of its operation. Proposed device comprises collector, stacking appliance, pressure surface, feed shaft, clamp and sheet feed line. Feed shaft comprises, at least, one transfer surface and resilient longer elements. Said longer elements extend radially outward, beyond transfer surface. Pressure appliance presses sheet to transfer surface. Stacking appliance displaces sheet by, at least. A part of its surface. Sheet feed line is composed of first and second guide. In placing sheets in stack, one sheet is available in collector. First sheet extends beyond collector into sheet feed line to stay in contact with stacking appliance. Second sheet is displaced to contact with stacking appliance with first sheet. Stacking appliance surface is displaced to shift sheets to make first sheet fit completely in collector. Cycle is repeated for next sheets.
