  • Patent number: 7445693
    Abstract: Two axially parallel rolls are pressed against each other in a device for producing and/or treating a moving material web. Sensor elements are arranged in the force transmission path running from the force-producing elements via the rolls, outside roll bodies of the two rolls. As a result of displacing the sensor elements out of the roll bodies of the rolls, the production of the rolls is less complicated and less expensive. No sensors have to be embedded in the roll bodies, which opens up the possibility of using standard rolls. In addition, the occasional grinding of the rolls can in this way be performed without any regard to the sensor elements. Nevertheless, the pressure prevailing between the rolls can continue to be measured directly, since the sensor elements are arranged in the transmission path of the pressing force.

  • Patent number: 7182837
    Abstract: A process and method which ‘locks in’ three-dimensional texturing added to a paper web by virtue of an adhesive material which is printed onto the surface of the web is generally disclosed. The adhesive may be applied to the web either before, during, or after the web is molded to increase the surface texture. The adhesive may be applied at relatively low pressure so as to preserve surface texture without significant deformation of the web. The cured adhesive material inhibits the web from reassuming a two-dimensional state or may contribute additional texture by rising above the surface of the web. This process may not only increase the bulk of the web when dry and wet, but also increase the wet resiliency, the wet strength, and the tactile properties of the web.

    Abstract: A process for producing wiping products and wiping products made by the process are disclosed. According to the present invention, a paper web is treated on both sides with a bonding material. After the bonding material is applied, the web is then subjected to a dry rush transfer process during which the web is conveyed from a first moving conveyor to a second moving conveyor. The second moving conveyor generally has a speed slower than the first moving conveyor causing a shearing force to be exerted on the web. The shearing force decreases the stiffness of the web. In one embodiment, an uncreped throughdried base web is used.

    Abstract: The method is for treating a liquid or slurry with an ultrasonic energy. A movable endless member is provided that is permeable to a liquid. A transverse foil is disposed below the member and extends across the member and a transducer is in operative engagement with the foil. The member is moved about rollers. The transducer generates pressure pulses into the foil to form implosion bubbles in the liquid disposed above the member. The implosion bubbles have a first diameter (d1). A gap is formed between the member and the foil. The gap represents a distance (d2) that is less than the diameter (d1) of the bubbles to prevent any bubbles of critical size to be captured in the gap.

    Abstract: Tension variations in the paper web on a paper machine are caused by successive draws and moisture fluctuations. Good strength properties require optimization of the draws. In addition, the tension variation induced by moisture must be minimized. The analysis of local modulus and the strain components can be used for determining optimal locations for profiling actuators in order to achieve good tension profile. Longitudinal strain components of the web, i.e. reversible elastic strain, permanent plastic strain and frozen-in strain relievable with water are continuously measured and determined and the variation of said longitudinal components is minimized by correcting the moisture content of the paper web in a dryer section of the paper machine and/or by optimizing the draws between dryer groups in the dryer section.

  • Patent number: 6855229
    Abstract: Disclosed is a composition for softening a wet laid cellulosic structure. A particularly preferred structure is an absorbent tissue. Further disclosed are tissue structures softened using the composition. The composition includes an effective amount of a softening active ingredient; a vehicle in which the softening active ingredient is dispersed; an electrolyte dissolved in the vehicle; and a bilayer disrupter. The electrolyte and the bilayer disrupter cooperate to cause the viscosity of the composition to be less than the viscosity of a dispersion of the softening active ingredient in the vehicle alone. Preferably, the softening active ingredient is a quaternary ammonium compound with the formula: (R1)4-m—N+—[(CH2)n—Y—R3]mX? the vehicle is water, the electrolyte is calcium chloride, and the bilayer disrupter is a nonionic surfactant. Also disclosed is a method of using the compound by adding it at a use concentration to the wet end of a papermaking process.

  • Patent number: 6852196
    Abstract: A method for applying a foam to a paper web is provided. Specifically, a foam is first formed from a liquid-based composition and a gas, such as air. Once formed, the foam is applied by a foam applicator to the web. In one embodiment, for example, the foam applicator applies the foam without substantially contacting the web. When applied with the foam, the web typically has a solids consistency less than about 95% by weight of the web. In some embodiments, one or more vacuum slots can be utilized in conjunction with the foam applicator to facilitate uniform application of the foam to the paper web.

  • Patent number: 6773550
    Abstract: The present invention relates to a method for coating of a fibrous web. According to the method a coating color with pigments is applied to the surface of the web and dried in order to form a coated web. The invention comprises using a coating color which contains pigments having a steep particle size distribution, a maximum of 35% of the pigment particles being smaller than 0.5 &mgr;m. The coating color is spread on the surface of the web with a coating speed of at least 1450 m/min, preferably over 1600 m/min. The coating pigment having a steep particle size distribution gives rise to a coating color which solidifies at much lower dry substance than conventional coating colors. In this way coating can be controlled at high speed without runnability and quality problems.

  • Publication number: 20040140075
    Abstract: Provided is a process for preparing a smooth and glossy surfaced paper web. The process comprises subjecting the paper web to shear by using calender rolls driven at different speeds or calender rolls with different diameters. The resulting paper has a totally different structure than the original paper, as it has a much smaller void structure and a much higher degree of bonding between the elements of the sheet. The process is particularly applicable to improving the electrical insulation properties of an aramid paper web.

    Abstract: A process for producing wiping products and wiping products made by the process are disclosed. According to the present invention, a paper web is treated on both sides with a bonding material. After the bonding material is applied, the web is then subjected to a dry rush transfer process during which the web is conveyed from a first moving conveyor to a second moving conveyor. The second moving conveyor generally has a speed slower than the first moving conveyor causing a shearing force to be exerted on the web. The shearing force decreases the stiffness of the web. In one embodiment, an uncreped throughdried base web is used.
