Machine for producing stacks of folded sheets of paper and method therefor

Abstract

Machine (1) for converting paper comprising a starwheel unit (10) equipped with at least one cylindrical body having a plurality of grooves (15), each of which is configured to receive a respective sheet (11) of a plurality of folded sheets (11) that are carried in turn, for example between two transmission belts (200, 201), along a feeding direction (101), for example a direction substantially tangential to the starwheel unit (10). The starwheel unit rotates about a rotation axis (110), for example in a counterclockwise direction, and discharges in turn the sheets (11) present in the grooves (15) onto a formation table (20, 120). More precisely, the folded sheets are discharged to achieve a predetermined angular release position, in order to form a stack (50) of folded sheets (11). The machine (1) can comprise a transfer means for transferring the formed stacks (50) from the table (20, 120) to said conveying means (30). The transfer means comprises a rotation means (60) arranged to transfer the stack (50) of folded sheets (11) from the table (20) to the conveying means (30) through a rotation of a predetermined angle.
