The present invention is to provide a sheet binding apparatus capable of performing stable pressure-bonding binding processing. A sheet binding apparatus includes a moving means configured to move at least one of the first binding portion and the second binding portion to bring the first binding portion and the second binding portion into pressure contact with each other, and a plurality of peeling members configured to apply peeling force in a direction opposite to a pressure-bonding direction to peel off a bound portion of the sheets stuck to the surface when the first binding portion and the second binding portion are separated by the moving means after pressure-bonding binding processing is performed. Here, the peeling force is applied by the plurality of peeling members at different timings.

An object of the present invention is to reduce loads during a punching process and to reduce punching time. A punching blade is provided with a blade edge portion including multiple peaks and multiple valleys formed alternately in a circumferential direction. A blade edge line of the blade edge portion has first areas corresponding to the valleys, second areas extending from the peaks to the valleys, and third areas connecting the first areas and the second areas. In a side view of the blade edge portion, the first areas form curved lines along first arcs having a center point on a punching axis, the second areas form curved lines along second arcs having center points located in areas between the punching axis and the highest points of the peaks, and the third areas form straight lines along common tangents to the first arcs and the second arcs.

An example device is provided in accordance with the present disclosure, which may be used for example for producing printed articles from printed sheets on which are imposed multiple pages of a printed article to be produced. The example device comprises a sheet feeder, a sheet path for the advance of a plurality of printed sheets fed by the sheet feeder, a cutter on the sheet path to cut the printed sheets in a direction perpendicular to the sheet advance direction, to form at least two sheet portions, and a folder on the sheet path downstream of the cutter, to fold the sheet portions.

Web-wound rolls with a web edge treatment with microspheres and processes to make the same are provided. The web-wound rolls include a substrate web having at least two web edges. One or more stripes of coated material are disposed adjacent to one or both of the web edges. The substrate web is wound upon itself in multiple revolutions about a central core, and each revolution is held substantially separate from the next by the one or more stripes of coated material.

A sheet stacker for use in a device including a stacker portion, a fence, and a guide face. The stacker portion includes a stacker face that is inclined at a predetermined angle with respect to a horizontal plane and receives a plurality of sheets ejected from above and stack the plurality of sheets on the stacker face. The fence includes an angled face to contact an end of the plurality of sheets stacked on the stacker face. The angled face rises in a direction in which the plurality of sheets is stacked, with respect to a lower side of the stacker face. The guide face guides the sheet conveyed along the lower side toward an outlet port to a lower end of the outlet port, the outlet port opening in an exterior of the device to remove the sheet to an outside of the device.
