Abstract
A sheet-processing machine includes a turning device. Sheets can be conveyed, by a sheet conveyor system, from a sheet guide cylinder in the turning device, and can be conveyed in a sheet conveyor direction on a sheet conveyor path. A sheet guide element is provided beneath or along the sheet conveyor path. A deionization device is assigned to the sheet guide element. The deionization device can provide positive and negative ions.
Claims15
A sheet-processing machine (1) comprising a turning device (3), sheets being receivable by a turning drum (17) from a storage drum (16) in the turning device (3) and conveyable in the sheet conveyor direction (BFR) on a sheet conveyor path, and a sheet guide element (9) being provided beneath and/or along the sheet conveyor path,
- characterized in that a deionization device (8) is assigned to the sheet guide element (9), the sheet guide element (9) being assigned, as a sheet guide plate (9), to a transfer region between a storage drum (16) and a turning drum (17), and the deionization device (8) comprising at least two discharge electrodes (12) that are spaced apart from one another and/or are arranged transversely to the sheet conveyor direction (BFR).
A method for conveying sheets in a sheet-processing machine (1), sheets being received by a sheet conveyor system (7, 17, 18) from a sheet guide cylinder (5, 16) and conveyed in the sheet conveyor direction (BFR) on a sheet conveyor path along a sheet guide element (9), the sheets being guided by the sheet guide element (9), the sheets being guided past a deionization device (8) assigned to the sheet guide element (9), and positive and negative ions being provided by a plurality of discharge electrodes (12) of the deionization device (8) to be able to equalize the alternating charge states on the sheet surface, a discharge electrode (12) comprising electrode tips that are alternatingly arranged and emit positive and negative ions.
