PCT No. PCT/DK82/00049 Sec. 371 Date Jan. 18, 1983 Sec. 102(e) Date Jan. 18, 1983 PCT Filed May 25, 1982.Device for the conveying of sheets from each of a plurality of sheet piles via a partially common conveyor track. This track extends in vertical direction along superposed stock holders. Adjacent to the sheet delivery side a driven roller is stationarily arranged above each pile. Each of these rollers can function both as suction roller for separating sheets from a pile and as friction roller for conveying sheets in the common track. For separating sheets from a pile, each pile can be brought by pneumatic means into short contact with a driven roller then functioning as a suction roller. For conveying sheets in the common track, each roller cooperates with a pressure roller. After a sheet in the common track has been gripped between a driven roller and a pressure roller, the sucting action of that driven roller is interrupted. |
