Abstract
A sheet processing machine receives sheets from a sheet feeder. The sheets are inspected and their trailing ends are trimmed. Subsequently, the sheets are turned and are split into a plurality of partial sheets or sheet pieces. The now trailing ends of the sheet pieces are trimmed. The sheet pieces are separated axially and are delivered to a sheet receiving device where the individual sheet pieces are deposited in various stacks.
Claims9
A sheet processing machine comprising:
- a first transverse sheet cutting device;
- means for moving sheets in a transport direction in the sheet processing machine past said first transverse sheet cutting device for cutting a trailing end of each sheet transversely to said transport direction in said first transverse sheet cutting device;
- a sheet turning device arranged downstream, in said transport direction, from said first transverse sheet cutting device, said sheet turning device turning each sheet and positioning said transversely cut trailing end of each sheet as a new leading end of the sheet;
- and
- a second transverse sheet cutting device arranged downstream, in said transport direction, from said sheet turning device, said second transverse sheet cutting device cutting a now trailing, originally leading end of each sheet transversely to said transport direction.
