Abstract:
A sheet processing apparatus configured to form a recessed portion at a portion at which a staple is driven into a sheet bundle from a sheet forming a surface of a side into which at least the staple is driven such that a sheet bundle to be discharged next on a sheet bundle stacking unit is stacked on a sheet bundle previously stacked on the sheet bundle stacking unit without catching on a staple of the previously stacked sheet bundle, and an image forming apparatus including the sheet processing apparatus.
Abstract:
An embossing stamp includes a stamp substrate and one or more stamp structures formed on the stamp substrate. The stamp structures have stamp surfaces extending from the stamp substrate. At least one of the stamp surfaces is non-planar.

Abstract:
There is provided a sheet post-processing apparatus capable of performing eco-stapling processing to prevent a decrease in binding force by the thickness of a sheet with a simple arrangement by changing a stapling count depending on the grammage and size of a sheet and the number of sheets in consideration of the change in binding force caused by the sheet size.
Abstract:
A process to mate a plurality of tissue webs includes in one embodiment providing first and second steel rolls and a second steel roll. The first steel roll has first protrusions, and the second steel roll has recesses. The embodiment includes forming a rotary nip between the first steel roll and the second steel roll, and advancing the plurality of tissue webs through the nip. The embodiment includes embossing first and second embossments into the plurality of tissue webs to connect the tissue webs to one another. The first protrusions press a first series of portions of the plurality of tissue webs into the recesses. The second embossments are created by one of pin-to-flat and pin-to-pin embossing. An apparatus suitable for carrying out the process is also disclosed.

Abstract:
A method of producing a packaging material in which a web of paper is provided with a pattern of printing ink at the same time as the web is subjected to a mechanical processing by means of which the areas of the web provided with printing ink are compressed to such an extent that the printing ink throughout within these compressed areas is located on a level flush with or below the level of the remaining areas of the web. As a result of the mechanical processing, it will be ensured that the printing ink is prevented from coming into contact with and giving undesirable impressions against the web in immediately preceding winding turns.
