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 system for embossing at least a portion of a web is provided comprising a first embossing roll having male embossing elements, a second embossing roll having male embossing elements, wherein the first and second embossing rolls define a first nip for receiving the web, and a third embossing roll having male embossing elements, wherein the second and third embossing rolls define a second nip for receiving the web, and wherein at least a substantial portion of the embossing elements of at least one of the first, second, and third embossing rolls are substantially oriented in the cross-machine direction.
Abstract:
An apparatus for embossing a web substrate is disclosed. The apparatus has a pattern roll having an embossing pattern disposed thereon, an anvil roll juxtaposed in an axially parallel relationship with the pattern roll, and an embossing roll juxtaposed in an axially parallel relationship with said pattern roll. The anvil roll has a hardness of less than about 40 P&J. The embossing roll has a hardness of greater than about 40 P&J.
Abstract:
An apparatus for embossing a web substrate is disclosed. The apparatus has first, second, and third pattern rolls. The first, second, and third patterns rolls each have respective first, second, and third pluralities of raised elements and recesses disposed thereon. A first nip is formed between the first and second pattern rolls and a third nip is formed between the first and third pattern rolls. The raised elements and the recesses of the first pattern roll are matingly engagable with the corresponding plurality of raised elements and recesses of the corresponding second and third pattern rolls. The first and second nips are both adapted to receive the web substrate and emboss the web substrate with the respective and corresponding embossing patterns when the web substrate is disposed within the respective nip.
Abstract:
A process for embossing a web substrate is disclosed. The process comprises the steps of: 1. disposing the web substrate in a circumferentially elongate nip formed between a pattern roll having a circumference and an embossing pattern disposed upon a surface thereof and a continuous belt disposed about at least a portion of the circumference of the pattern roll; 2. providing the continuous belt with a surface speed corresponding to a speed of the web substrate; and, 3. juxtaposing the embossing pattern upon the web substrate while the web substrate is disposed within the elongate nip.
Abstract:
The present invention provides a process for embossing a web substrate. The process comprises the steps of: (a) juxtaposing a first pattern roll in an axially parallel relationship with a second pattern roll forming a first nip; (b) providing the first pattern roll with first pluralities of raised elements and recesses comprising a first embossing pattern; (c) providing the second pattern roll with second pluralities of raised elements and recesses comprising a second embossing pattern; (d) contacting the web substrate at the first nip; (e) embossing the web substrate; (f) juxtaposing the first pattern roll in an axially parallel relationship with a third pattern roll to form a second nip; (g) providing the third pattern roll with third pluralities of raised elements and recesses comprising a third embossing pattern; (h) after step (e), contacting the embossed web substrate at the second nip; and, (i) further embossing the embossed web substrate at the second nip.
Abstract:
An embossing system for embossing at least a portion of a web is provided comprising a first embossing roll having male embossing elements, a second embossing roll having male embossing elements, wherein the first and second embossing rolls define a first nip for receiving the web, and a third embossing roll having male embossing elements, wherein the second and third embossing rolls define a second nip for receiving the web, and wherein at least a substantial portion of the embossing elements of at least one of the first, second, and third embossing rolls are substantially oriented in the cross-machine direction.
