A sheet processing device includes a tape binding processing unit, a paper discharge unit, and a control unit. The tape binding processing unit performs tape binding processing on a sheet bundle. The paper discharge unit discharges the sheet bundle subjected to the tape binding processing onto a paper discharge tray. The control unit is configured to control at least one of the tape binding processing unit and the paper discharge unit, such that a first tape binding of the first bundle of sheets and a second tape binding of the second bundle of sheets are not in contact with each other when the first bundle of sheets and the second bundle of sheets are stacked on the paper discharge tray.

A method for fixing a first surface to a second surface. The method comprises depositing a first layer of nanocellulose on the first surface; bringing the first layer of nanocellulose into contact with the second surface or with a second layer of nanocellulose deposited on the second surface; and fixing the first layer of nanocellulose to the second surface, the second surface containing cellulose, or to the second layer of nanocellulose by a step of ultrasonic welding, which results in a first zone comprising the first layer of nanocellulose, where the first surface is fixed to the second surface, and a second zone around the first zone, where the first surface is not fixed to the second surface.

A surface protector system for protecting selected portions of floor surfaces, wherein the system includes first and second surface protectors that are connected together to form a dust-proof connection between the first and second surface protectors.

A printable blank sheet includes a sheet with a first layer and a second layer attached to a bottom side of the first layer. Slit-over-perforation lines extend through the sheet. The slit-over-perforation lines include cuts running through the first layer, and perforations running through the second layer. A folder is cut into the sheet with a periphery of the folder defined by the slit-over-perforation lines.

A supply (22) of sheet stock material (24, 34) for a dunnage conversion machine (26) that is readily spliced to another supply includes (a) one or more plies of sheet material (24, 34) having (i) multiple longitudinally-extending sections, including a center section (42) bounded by lateral sections (40), where the lateral sections (40) are folded over a common face of the center section (42) along longitudinal fold lines (44) at lateral edges of the folded sheet material, and (ii) a leading end (60) and a trailing end (62) at respective longitudinally-opposite ends of the sheet material, where the lateral sections (40) are separated from the center section (42) adjacent the leading end (60) and adjacent the trailing end (62) along respective lines of separation; and (b) a splicing adhesive (76) applied to the sheet material adjacent the leading end (60) or the trailing end (62) on both the center section (42) and each of the lateral WO 2020/092578 A1 sections (40) to facilitate splicing each section to respective sections of two supplies.
