  • Publication number: 20140237848
    Abstract: Systems and methods are provided for balancing air flow in dryers of printing systems. The dryer includes a heating element, top flow generator, and bottom flow generator. The heating element is within the dryer, and heats a web of printed media. The top flow generator directly projects a first jet of gas onto a top side of the web. The first jet of gas deflects air proximate to the web. The bottom flow generator directly projects a second jet of gas onto an opposing side of the web. The second jet strikes the web at substantially the same location as the first jet, and compensates orthogonal force applied to the web by the first jet. Furthermore, the top and bottom flow generators are both oriented to project the jets partially in the direction of travel of the web.

  • 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.

A first chamber is positioned near the control surface, with the first chamber having a gas introduction device. A second chamber is positioned near the control surface, the second chamber having a gas withdrawal device. The control surface and the chambers together define a region wherein the adjacent gas phases possess an amount of mass. Upon inducement of at least a portion of the mass within the region, the mass flow is controlled to significantly reduce dilution of the gas phase component in the adjacent gas phase. This is accomplished through the introduction of a controlled gas stream thereby reducing the flow of an uncontrolled ambient gas stream due to pressure gradients in the system.

  • Patent number: 7384509
    Abstract: A method for controlling the moisture profile of a paper web or board web processed in a heated multi-roll calendar to optimize the qualities of the paper or board, especially gloss. The method is characterized in that the moisture measurement is carried out both on either surface of the web and as a through-measurement, and the measurement results thus obtained are specified by a thermodynamic model which calculates the moisture of the web in three layers, and that the results thus obtained are used for controlling the supply of moisture to the web.

  • Publication number: 20080052947
    Abstract: After rinsing, a liquid mixture (IPA+DIW) is supplied to a substrate surface while rotating a substrate at a first rotating velocity which is relatively high to thereby replace the rinsing liquid adhering to the substrate surface with the liquid mixture. In this way, the rinsing liquid adhering to the gaps between the patterns formed on the substrate surface is replaced with the liquid mixture. Subsequently, DIW is supplied to the substrate surface in a condition that the rotation of the substrate is stopped or that the substrate is rotated at a second rotating velocity which is relatively low to thereby form a puddle-like liquid layer with DIW. In this way, the liquid mixture of the surface layer part is removed from the substrate surface while leaving almost all the liquid mixture adhering to the gaps between the patterns. After that, the liquid layer is removed from the substrate surface to thereby dry the substrate surface.

  • Patent number: 7147754
    Abstract: A system for maintaining calender rolls of a paper machine clean when producing high-gloss paper or coated paper, such as LWC or MWC. To prevent a coating agent, such as coating dye, from adhering onto and soiling a smooth surface of a calender roll, with an overheating phenomenon, the system has a second measurement station (10) provided with measuring and indicator means for producing an output indicating soiledness of the web (W) or a humidity profile. When the output of the second measurement station (10) indicates excessive soiledness or an uneven humidity profile, the system performs at least one of: cleaning the surface of the smooth-surfaced calender roll; changing the nip load in the calender (5); making a correction adjustment of the CD-directional humidity profile of the web (W); cutting the web (W) and conducting it into the pulper; and/or changing the running speed of the web (W).

  • 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.

  • Patent number: 7005010
    Abstract: A system for processing a workpiece includes an inner chamber pivotably supported within an outer chamber. The inner chamber has an opening to allow liquid to drain out. A motor pivots the inner chamber to bring the opening at or below the level of liquid in the inner chamber. As the inner chamber turns, liquid drains out. Workpieces within the inner chamber are supported on a holder or a rotor, which may be fixed or rotating. Multi processes may be performed within the inner chamber, reducing the need to move the workpieces between various apparatus and reducing risk of contamination.

  • Patent number: 6910282
    Abstract: A web (16) running from an opening nip (K1) between a cylinder (10) and a supporting fabric (18) toward a roll (14), is supported by a negative pressure created by a blow box (30). In an intensified negative pressure region (34?), i.e. close to the disengaging point (40) between the supporting fabric and the cylinder, the pressure is greater than at a distance from this disengaging point. The negative pressure is controlled according to parameters which act on the runability of the web and which can be varied, such as web velocity, web solid contents, pulp composition, paper or paper board quality, web grammage, a characteristic of the web, such as porosity, traction acting in the web, or web tension, cylinder temperature, and/or the running situation, such as a web break, a threading situation, or a normal run, so the desired runability is maintained between the cylinder and the roll.

  • Patent number: 6860968
    Abstract: A process for producing tissue webs is disclosed. More particularly, the present invention is directed to an improved process for drying webs. According to the present invention, a formed web still containing a substantial amount of moisture is passed through a nip formed between a press roll and a heated drum. When passed through the nip, the web is placed on a porous fabric. The web is then carried through the nip for a period of time and subjected to temperatures and pressures sufficient to create a steam front which travels through the web and expels a significant amount of moisture from the web through the porous fabric.
