Abstract
Disclosed is a blade for a saddle folding unit that can saddle-fold a sheet. At the edge of a folding side of the sheet in the blade, a protrusion portion protruding in a pushing direction of the blade is provided.
Claims19
A blade for a saddle folding unit that facilitates saddle-folding a sheet, the blade comprising:
- a protrusion portion that protrudes in a pushing direction of the blade on an edge of a folding side of the sheet in the blade,
- wherein the protrusion portion comprises a plurality of protrusions aligned in a thickness direction of the blade,
- wherein the protrusions protrude in the pushing direction, the protrusions being closer together toward a center side in the thickness direction when viewed from a direction orthogonal to the pushing direction and the thickness direction.
A saddle folding method for saddle-folding a sheet, comprising:
- pushing a blade comprising a protrusion portion that protrudes in a pushing direction of the blade on an edge of a folding side of the sheet between a pair of folding rollers, wherein the blade comprises a plurality of protrusions aligned in a thickness direction of the blade, and the plurality of protrusions engage the folding side of the sheet when pushing the blade;
- and
- pushing the blade comprising protrusions closer together toward a center side in the thickness direction when viewed from a direction orthogonal to a pushing direction and the thickness direction.
A blade for a saddle folding unit that facilitates saddle-folding a sheet, the blade comprising:
- a protrusion portion that protrudes in a pushing direction of the blade on an edge of a folding side of the sheet in the blade,
- wherein the protrusion portion comprises a plurality of protrusions aligned in a thickness direction of the blade, and
- wherein the protrusions protrude in the pushing direction, the protrusions being closer together toward one side in the thickness direction when viewed from a direction orthogonal to the pushing direction and the thickness direction.
