Patent number: 8206555Abstract: 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.Type: GrantFiled: December 1, 2011Date of Patent: June 26, 2012Assignee: Metso Paper Karlstad ABInventors: Ingvar Berndt Erik Klerelid, Hans Ivarsson, Johan Ulf Ragard, Frank Stephen Hada, Paul Douglas Beuther, Jeffrey Dean Holz

Publication number: 20120121814Abstract: 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.Type: ApplicationFiled: November 11, 2010Publication date: May 17, 2012Inventors: Robert Eugene Krautkramer, Douglas Wayne Stage, Frank Stephen Hada

Publication number: 20120103550Abstract: 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.Type: ApplicationFiled: November 4, 2011Publication date: May 3, 2012Inventors: Paul Douglas Beuther, Frank Stephen Hada, Jeffrey Dean Holz, Hans Ivarsson, Ingvar Berndt Erik Klerelid, Johan Ulf Ragard

Patent number: 7938932Abstract: 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.Type: GrantFiled: August 30, 2010Date of Patent: May 10, 2011Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Michael Alan Hermans, Cristina Asensio Mullally, Stephanie Lee Berube, Frank Stephen Hada, Lacey Leigh Hansen, Jeffrey David Mathews

Publication number: 20110095116Abstract: 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.Type: ApplicationFiled: October 27, 2009Publication date: April 28, 2011Inventors: Frank Stephen Hada, James Leo Baggot, Robert Eugene Krautkramer, Steven James Wojcik
