Abstract (en)

[origin: EP3378811A1] The sheet stacker (1) comprises a sheet conveyor arrangement (3), configured for feeding a plurality of sheets (C) in succession in a sheet feeding direction (F), said sheet conveyor arrangement having a sheet discharge end (17). The sheet stacker further comprises a stacking bay (5), wherein sheets delivered by the sheet conveyor arrangement at the sheet discharge end thereof are formed into stacks (S). The stacking bay (5) comprises a stacker platform (19). The stacker platform (19) supports a stack surface (25) movable in a direction parallel to a feeding direction (F) of the sheets (C) in the stacking bay (5), configured and controlled to perform a reciprocating staggering motion to form staggered bundles (B) of sheets. The pitch (P) of the staggering motion is set as a function of at least one production parameter, such as the length of the sheets in the staggering direction.
