Abstract

1311031 Delivering sheets RICOH KK 20 May 1970 [13 Sept 1969] 24375/70 Heading B8R A device for discharging a sheet supported on a cylinder, e.g. the impression cylinder 3 of a rotary offset printing machine, comprises a roller 22, (23), Fig. 3 (not shown), pivotally supported about a common axis extending parallel to the axis of the cylinder, e.g. adjustably positioned on a shaft (21) removably located between a pair of pivotable support arms 12, (13), biasing means, e.g. springs (15), (16), being provided for biasing the rollers towards said cylinder and abutment means, e.g. fixed abutments 17, (18) on the frame of the device and adjustable limiting screws 19, (20) on the support arms 12, (13), being provided for limiting the displacement of the rollers towards the cylinder. Copy sheets gripped by pawls 3a in the impression cylinder surface are fed between the nip of impression cylinder 3 and a blanket cylinder 2, then between the nip of the pair of rollers 22, (23) and impression cylinder 3 and are then stripped from the impression cylinder 3 with the aid of biased pawls 30 and fed between a pair of pressing rollers 26, (27), located at the free ends of arms 28, (29) supported on the shaft (21), and a delivery roller 6. The pressing rollers 26, (27) rest on the delivery roller 6 which is drivingly connected via gearwheels 7, 8, 9 to the rotating impression cylinder 3, and coact with rings 31, (32) on the delivery roller 6 to stiffen the copy sheet by bending as it is delivered to a stack in a tray 5. The impression cylinder 3 may be movable so as to contact the blanket cylinder 2 and rollers 22, (23) only when a copy sheet is fed therebetween.
