Abstract
A separating unit for flat sheet material has a rotating separating drum with suction openings on its outer face. The material to be separated is run tangentially between the separating drum and a suction drum. The separating drum has suction holes ahead of the suction openings that initiate the evacuation of air between the sheet and drum by a pulling effect lower than that of the suction openings.
