Process and apparatus for separating flat sheet material

摘要

Flat material sheets are separated by a separating drum rotating on a supporting plate that pulls the sheets separately one after another off a pile and directs the separated sheets toward a subsequent transporting system. The separating drum comprises a stator with sectorial suction channels extending circumferentially and a rotor with suction openings communicating with the suction channels. The communication between the suction openings and suction channels is made in such a way that the sheet material adjacent to the edge running on the supporting plate is attached to the drum by the action of the vacuum earlier than in other areas. This area may be released later than the other areas.
