Abstract
An apparatus for stacking sheets has a conveyor having a downstream end spaced upstream in a horizontal transport direction from a stacking station for delivering the sheets continuously one after the other at a predetermined upper level in the direction to the station and a main platform vertically displaceable in the stacking station between an upper position below the upper level and a lower position. An auxiliary platform below the upper level is formed by a plurality of parallel rods horizontally displaceable in the direction between an extended position in the station above the main platform and a retracted position upstream of the main platform. A plurality of vertically extending separator elements having bent-over upper ends projecting downstream between the rods in the transport direction are and displaceable between a separating position projecting into the station between the auxiliary platform and the upper level and engaged between trailing edges of sheets and a withdrawn position out of the station between the station and the conveyor downstream end. Each element has a vertical length greater than the vertical distance between the auxiliary platform and the upper lev…
