20080271862 | Tissue sheets having good strength and bulk - A method of making soft, strong, high bulk tissue is disclosed. The method includes pre-conditioning a wet web by straining the wet web in the cross-machine direction prior to transferring the wet web to a throughdrying fabric. The pre-conditioned web provides improved sheet softness and conforms more readily to the surface contour of the throughdrying fabric, thereby creating greater caliper (bulk) in the resulting dried sheet. The bulk is maintained during a subsequent creping step by maintaining the dried sheet in registration with the throughdrying fabric when the dried sheet is applied to the surface of the creping cylinder. | 11-06-2008 |
20080314540 | Method for dewatering a fabric - A method of dewatering a fabric includes contacting the fabric with an endless wicking substrate. | 12-25-2008 |
20090321552 | Moldable paper product - A paper towel sheet is disclosed which contains a low strength adhesive material strategically applied to selected areas of the sheet. The adhesive areas enable the user to optionally fold and form the sheets into three-dimensional shapes suitable for a variety of new uses, such as making “bowls” for holding popcorn or other food, for example. | 12-31-2009 |

20100167896 | Method For Perforating Tissue Sheets - Curvilinear or other complex perforation patterns for paper products, such as paper towels and bath tissue, can be produced using a differential speed perforation nip formed between a rotating pattern roll and a moving anvil surface. The relative speed between the perforation elements on the surface of the pattern roll and the anvil surface shears the web at the perforation points. | 07-01-2010 |

20100326616 | Papermaking Machine Employing An Impermeable Transfer Belt, and Associated Methods - A papermaking machine for making paper includes a forming section, a press section, and a drying section. The paper web is pressed between two press members while enclosed between a press felt and a transfer belt having non-uniformly distributed microscopic depressions in its surface, the web following the transfer belt from the press to a transfer point at which the web is transferred via a suction transfer device onto a structuring fabric, the web then being dried on a drying cylinder. The transfer point is spaced a distance D from the press nip selected based on machine speed, a basis weight of the web, and the surface characteristics of the transfer belt, such that within the distance D a thin water film between the web and the transfer belt at least partially dissipates to allow the web to be separated from the transfer belt. | 12-30-2010 |
20110095116 | Coreless Tissue Rolls - Coreless rolls of tissue, such as rolls of bath tissue or paper towels, are produced by winding tissue logs on a mandrel having retractable pins. During winding, the pins extend and penetrate the first several windings of the log as it is initially wound, which prevents slippage. After the winding is complete, the pins retract to allow the tissue log to slide off of the mandrel for subsequent slitting into individual product rolls and packaging. The penetration of the pins into the first several windings of the log tends to mechanically entangle and structurally unify those windings to create a “soft core”. At the same time, the properties of the tissue sheets within the soft core are the same as the other sheets within the roll and are therefore usable by the consumer. | 04-28-2011 |

20120103550 | Apparatus With An Impermeable Transfer Belt In A Papermaking Machine, And Associated Methods - An apparatus for transferring a wet paper web from a press nip to a drying cylinder of a papermaking machine, and for structuring the web, includes an impermeable transfer belt that passes through the press nip along with the paper web, and a permeable structuring fabric for transfer of the web onto the drying cylinder, the structuring fabric being arranged in a loop within which a suction transfer device is disposed. A web-contacting surface of the belt has a non-uniform distribution of microscopic-scale depressions, and a suction zone of the transfer device includes a transfer point spaced a distance D from the press nip. The belt is arranged to bring the web into contact with the structuring fabric in the suction zone for a length L, such that suction is exerted on the paper web to transfer the paper web from the belt onto the structuring fabric at the transfer point. | 05-03-2012 |
20120121814 | Sealed Metered Coating Apparatus - The present invention relates to an apparatus for applying a coating, preferably a high viscosity coating to a supported web, preferably tissue. The apparatus of the present invention comprises a sealed coating chamber that can be supplied with coating material under pressure. The chamber further comprises a metering device at its trailing edge, which applies a thin layer of coating material to an applicator roll. In general, the coater is designed to have a small footprint, allowing it to fit into tight locations and be readily adapted for use in existing tissue manufacturing and converting processes. The coater also has the advantage of having a sealed coating chamber, which permits coating material to be supplied under pressure and preventing contamination of the coating material by debris common to the coating process. | 05-17-2012 |

The cut-off method and apparatus include a conveying surface over which a moving web is conveyed and a web cut-off assembly opposing the conveying surface. The web cut-off assembly includes a first arm with a first web gripping surface and a second arm with a second web gripping surface, the first and second web gripping surfaces being movable relative to one another. To complete a breaking event, the first and second web gripping surfaces contact the moving web at a first contact point and second contact point. The contact points move from a first spaced apart relationship to a second spaced apart relationship causing a break in the web between the first and second web gripping surfaces. | 01-17-2013 |
20130153703 | Method and Apparatus for Winding Webbed Material with Mandrel Position Control - A method and apparatus for winding a moving web upon a mandrel is disclosed. A moving web with a leading edge is conveyed towards a mandrel. The mandrel is adapted to allow the moving web to adhere to the mandrel at a specific circumferential location on the mandrel. To enable control of the location of the mandrel, the mandrel further includes a reference input to identify the specific circumferential location. A position sensor is used to determine the position of the reference input. The position of the specific circumferential location of the mandrel is controlled with a position drive control that controls the rotational speed of the mandrel. The position drive control sets the rotational speed of the mandrel to allow transfer of the leading edge of the moving web near the specific circumferential location. | 06-20-2013 |
20140238210 | TISSUE PERFORATING APPARATUS - The present invention provides a perforating station comprising two or more discrete perforating stations, the stations synchronized with one another to cut a line of perforations across a web, such as a web of tissue paper, moving at high speeds. By providing two or more synchronized perforating stations the perforating station may increase the number of impacts per minute compared to prior art perforating devices. | 08-28-2014 |
