Abstract
An apparatus forms stacks of interfolded sheets. First and second folding rolls receive the plurality of sheets, move the plurality of sheets through the nip, and fold the plurality of sheets into a stack of interfolded sheets downstream of the nip. A packing finger is associated with each folding roll, and the respective packing fingers move between a retracted position and an extended position relative to the corresponding folding roll with alternate movement relative to each other between the retracted position and the extended position to engage the plurality of sheets and form the stack of interfolded sheets. A fluid delivery system delivers fluid to a sheet in the plurality of sheets at or after the folding rolls.
Claims18
An apparatus for forming stacks of interfolded sheets from a plurality of sheets, the apparatus comprising:
- first and second folding rolls being opposed to one another to form a nip, the first and second folding rolls being configured to receive the plurality of sheets, move the plurality of sheets through the nip, and fold the plurality of sheets into a stack of interfolded sheets downstream of the nip;
- a first packing finger associated with the first folding roll;
- a second packing finger associated with the second folding roll;
- the first packing finger being adapted and configured to move between a retracted position and an extended position relative to the first folding roll;
- the second packing finger being adapted and configured to move between a retracted position and an extended position relative to the second folding roll;
- the first and second packing fingers being adapted and configured to alternate movement relative to each other between the retracted position and the extended position to engage the plurality of sheets and form the stack of interfolded sheets;
- and
- a fluid delivery system adapted and configured to deliver a fluid to a sheet in the plurality of sheets at or after the folding rolls, the fluid being a liquid.
