Abstract (en)

[origin: EP3381845A1] A sheet support structure (14) comprising a rotary drum (18) having a peripheral wall (26) formed with apertures (40) and delimiting a vacuum chamber (42) formed inside of the drum, a perforated belt (20) having a portion (20b) trained around at least a part of the peripheral wall (26) of the drum (18) and a flat portion (20a) remote from the drum, and a suction system (30) arranged to create an underpressure in the vacuum chamber (42) and at the perforations (28) of the belt (20), characterized in that at least one of the belt (20) and the peripheral wall (26) of the drum (18) has an array of embossments (44) that form spacers between the belt (20) and the peripheral wall of the drum (18) and define a distribution manifold connecting the apertures (40) of the drum to the perforations (28) of the belt portion (20b) on the drum.
