Abstract
A folding method includes feeding a sheet to be folded to a folding unit, folding the sheet repeatedly by the folding unit, thereby creating a folded package, and discharging at least a part of the folded package from the folding unit. While at least a part of the folded package is discharged from the folding unit in the step of discharging, a part of the sheet is held back. The method includes unfolding at least one fold of the folded package. A folding apparatus is provided for carrying out the method.
Claims4
A folding apparatus, comprising:
- a folding unit configured to repeatedly fold a sheet in order to create a folded package;
- a feed unit configured to feed a sheet to be folded to the folding unit;
- a delivery unit configured to discharge the folded sheet;
- and
- a control unit configured to control the feed unit to feed the sheet to the folding unit, control the folding unit to fold the sheet repeatedly to create the folded package, and control the delivery unit to discharge at least a part of the folded package from the folding unit,
- wherein while at least a part of the folded package is discharged from the folding unit, the control unit is configured to control the feed unit to retract back a part of the sheet so as to unfold at least one fold of the folded package,
- wherein after at least a part of the folded package has been discharged from the folding unit, the control unit is configured to control the folding unit to repeat folding the sheet so that at least a section of the sheet which has not been folded is folded, thereby creating a new folded section, and
- wherein the new folded section and the previously folded package are continuous.
