Abstract
A delivery of a sheet-processing machine for transporting a sheet along a sheet-conveying path to a stacking device, includes a sheet braking device engaging, during operation, with an underside of a sheet and retarding it by suction belts or the like. A suction region is adjacent to and upstream of the sheet braking device. A suction device applies suction, in the suction region, to the underside of the sheet. A brake carriage carries the sheet braking device and the suction device and is displaceable between selective positions within a segment of the path. A stationary first guide device has a first sheet guide surface segment set back upstream from the sheet braking device. A second guide device has a guide element displaceable by the brake carriage and forming a second sheet guide surface segment between the sheet braking device and the first sheet guide surface segment. The second segment, together with the first segment, form a combined sheet guide surface having a telescopically variable length. The guide element assumes first and second relative positions with respect to the brake carriage in first and second operating modes of the delivery. In the first position, the guid…
