Embodiment Construction

[0033] figure 1 Parts of the output unit 01 and the final printing unit 02 of a machine for processing sheet-fed paper, for example a sheet-fed printing press, are shown in side view, here preferably in an assembly and in-line configuration Form sheet-fed lithographic printing presses. The printing cylinder 11 of the printing unit 02 transfers the sheet 22 to the sheet of the output unit 01 after the last printing ink has been applied to the sheet 22 in contact with a blanket cylinder not shown. Sheet transport system 12. Alternatively, other devices, such as a varnishing device, can also transfer the individual sheets 22 to the output device 01 or the individual sheet transport system 12 . The sheet transport system 12 comprises two closed chains 13 deflected on sprockets 14 , 15 . The chain guides arranged on the side frames of the output device 01 guide the lower and upper return runs 16, 17 of the chain 13 respectively in a curved, first oblique climb from the sprocket ...

Abstract

The invention relates to a gripper carriage for transporting a sheet (22) in a sheet transport direction (29) along a sheet transport path (23), wherein the gripper carriage (19) has a wall (20) and areflector (27), the reflector (27) being associated with a flank (07) of the wall (20), which is trailing in relation to the sheet transport direction (29).

Description

technical field [0001] The invention relates to a gripper trolley, a sheet-fed machine with a gripper trolley and an integrated radiant dryer, and a device for conveying by means of a gripper trolley in an output device of a sheet-fed processing machine Sheet-fed approach. Background technique [0002] The sheet-sheet output device known from DE 29616235 U1 feeds the sheets by means of a gripper trolley which is guided on a revolving chain along the sheet-sheet transport path. The gripper carriages each grip the leading edge of the sheet and pull the sheet on the sheet transport path also past the radiant dryer. [0003] US4530495A discloses a machine for processing sheets with a radiation dryer, wherein the rear running face of the gripper trolley has an angle of less than 90° to the sheet conveying plane in order to reduce the irradiance of the sheets Area. [0004] EP 0 252 602 A1 discloses a sheet-fed machine with a radiant dryer, in which the gripper carriage has ref...
