  • Patent number: 8852398
    Abstract: The present invention provides tissue products having increased CD stretch, which may be manufactured using a process in which the nascent web is subjected to two distinct rush transfers. The first rush transfer occurs when the web is transferred from the forming fabric to the transfer fabric, i.e., the “first position,” and the second occurs when the web is transferred from the transfer fabric to the through-air drying fabric (TAD) fabric, i.e., the “second position.” The overall speed differential between the forming fabric and the TAD fabric may be, for example, from about 10 to about 50 percent, with the amount of rush transfer being divided between the first and second position in a manner sufficient to achieve the desired CD stretch and other sheet properties.

  • Patent number: 8834678
    Abstract: The present disclosure relates generally to a tissue product having a creping composition disposed onto at least one surface thereof to increase the softness of the article, while retaining or improving manufacturing efficiency. The tissue products also have a sizing agent that increases the Wet Out time, without negatively impacting softness or machine runability. Preferably the creping composition comprises a cationic component and a film forming component, both of which are preferably water soluble. The cationic component carries a cationic charge that is capable of forming ionic bonds with the negatively charged fibers of the tissue web, thus providing a retention mechanism by which the creping composition is retained on the sheet. The overall retention of the creping composition on the sheet reduces the concentration of the composition in the machine process water, improving machine operability and runability.

  • Patent number: 8277609
    Abstract: The intrinsic tissue sheet properties of tissue sheets wound into a parent roll during manufacturing can be purposely varied in order to provide a z-directional gradient within the parent roll. For example, the moisture content of the tissue sheet can be made lower in the core region of the parent roll and greater in the outer region of the parent roll. Such gradients can ultimately provide more uniformity of the intrinsic property within the final tissue product.

  • Patent number: 8137505
    Abstract: A system and process for producing tissue webs is disclosed. The tissue webs are formed from an aqueous suspension of fibers and dried using a through-air dryer. During formation of the web, the web is transferred from a transfer fabric to a throughdrying fabric and then conveyed around a drying cylinder of a through-air dryer. In accordance with the present invention, a pressurized roll emits a gaseous stream through a pressurized zone that pushes and transfers a wet web from a transfer fabric to the throughdrying fabric. The amount of pressure used during the transfer can vary depending upon the particular application and may be used to control the bulk of the web. By using a pressurized transfer roll, the amount the throughdrying fabric is wrapped around the drying cylinder of the through-air dryer can be maximized for increasing the efficiency of the system and the process.

  • Publication number: 20090056894
    Abstract: The intrinsic tissue sheet properties of tissue sheets wound into a parent roll during manufacturing can be purposely varied in order to provide a z-directional gradient within the parent roll. For example, the moisture content of the tissue sheet can be made lower in the core region of the parent roll and greater in the outer region of the parent roll. Such gradients can ultimately provide more uniformity of the intrinsic property within the final tissue product.

  • Patent number: 7470345
    Abstract: Spirally wound single-ply web products having a chemical additive applied to at least one surface exhibit desirable roll bulk characteristics and softness properties. The rolled products can be made from a single-ply tissue web formed according to various processes. Once formed, the web is subjected to a shear-calendering device that increases the Fuzz-On-Edge properties of the web and preserves the bulk of the web when wound. The shear-calendered web then has a chemical additive applied to at least one surface by a non-compressive application method helping to maintain the Fuzz-On-Edge properties of the web.

  • Patent number: 7377994
    Abstract: A web is threaded in the reeling of a paper or board web, by passing a web tail strip (W) into a reeling nip between a reeling drum (10) and a reel spool (12), on which a web roll is formed. The tail strip (W) is passed into the reeling nip by a suction zone (20) which extends substantially around the entire reeling drum circumference and is (10) in an area where a full-width web runs during reeling, so that the tail strip (w) can be conducted directly along the suction zone (20). The suction zone (20) is placed in the longitudinal direction of the reeling drum (10), i.e. in the width direction of the web.

  • Patent number: 7294232
    Abstract: A dry end of a tissue machine is made shorter by close-coupling a reel-up to the drying section and supporting the web from the drying section to the reel-up by a foil or a belt such that web stability is maintained, thus allowing high-speed operation. The foil's downstream edge can form a nip with the paper roll and nip load can be controlled by controlling pivotal movement of the foil. The reel-up can include a calendering belt for calendering the web as it passes through a nip between the belt and a reel drum supported on the belt, and a rotatable reel spool on which a paper roll is wound in nipping engagement with the reel drum. Alternatively, the reel drum can be eliminated and the paper roll can be supported on the belt. A composite shaftless core for winding is also disclosed.

  • Patent number: 7178140
    Abstract: Less data to transmit from a server to a virtual machine on a client is achieved by transmitting only those methods of classes that the executed application actually requires. This is accomplished by taking the classes of the targeted application and statically determining which methods of these classes, as well as of the library classes, can actually be used by the application. A method usage map of usable methods for each class is saved in a file. When the request to download is received from the client, the server consults this map and selectively transmits only those methods that are in it. This saves download time and memory space in the virtual machine and speeds up execution.

  • Patent number: 7112258
    Abstract: A dry end section for a paper-making machine for producing a high-bulk tissue is provided. Such a machine comprises a through-air dryer adapted to finally dry a paper web and a through-air drying fabric configured to transport the web through the through-air dryer. A separating device is included for facilitating separation of the web from the through-air drying fabric. A reel is also provided and is configured to receive the web thereon. The web is received directly on the separating device or on a fabric wrapped about the separating device. In some instances, the web may be compressed between the separating device and an adjacent roll or by a web-compressing device disposed along the fabric transporting the web. The web is then transported to the reel directly from the fabric or other support mechanism extending between the separating device and the reel, without free draw of the web. Associated methods are also provided.
