Abstract (en)
[origin: EP0386470A2] The invention relates to a device for scanning sheet lengths in a sheet-processing machine, in particular a rotary sheet printing machine, in which a feeder aligns the sheets to be printed against stops for the front edge of the sheets and lifts them individually from a stack (1) of sheets. The device comprises suction-air measuring nozzles (8) which are aligned with the rear edge of the sheets and have in their connection with a suction-air source switching elements (10, 11) in the circuit of the machine drive. <??>The inventive feature is the arrangement of such suction-air measuring nozzles (8) in the feeder and their alignment with the rear edge of the topmost sheet (3) in the stack (1) of sheets, the design features being intended to make it possible for existing machines to be retrofitted using simple means. <IMAGE>
