Abstract
The holding-down arrangement for holding down a sheet (24) in a sheet-bearing region of a sheet-processing machine, in particular of a folding machine, includes a plurality of blowing devices (19, 21) which, during use, are directed toward a sheet (24) and direct an air jet (20, 22) onto the sheet (24). The holding-down arrangement may be fitted in a sheet-aligning device which is arranged downstream of a sheet infeed and includes a sheet-bearing device (12), on which an incoming sheet (24) comes to rest.
Claims6
A sheet-aligning device for a sheet-processing machine which is arranged downstream of a sheet infeed, comprising
- a sheet-bearing device, on which an incoming sheet comes to rest, and
- at least one holding-down arrangement arranged above said sheet-bearing device and comprising a plurality of blowing devices which are directed toward said sheet-bearing device and direct an air jet onto said sheet, wherein an aligning rail extends in a sheet-running direction, the aligning rail being adjustable in an adjusting region transversely to the sheet-running direction and above said sheet-bearing device for aligning a sheet, and wherein said holding-down arrangement is arranged at a higher level in said adjusting region than said aligning rail.
