20080196854 | Sieve Mechanism For the Production of Paper, and Method For the Treatment of Non-Woven Fibers - To increase the processing speed of a sieve mechanism ( | 08-21-2008 |
20090114359 | Method For Use In The Wet End Of A Paper Machine, Cardboard Machine Or An Equivalent Web Forming Machine - The invention relates to a method in the wet end of a web forming process. In the method, at least one electrode pair ( | 05-07-2009 |
20090272508 | METHOD AND APPARATUS FOR TREATMENT OF PAPER STOCK - A sheet formation section of a paper machine includes a sensor that measures a first characteristic of a sheet of paper being formed. The sensor may measure a characteristic such as streaking, rises, depressions, or smoothness. The sheet formation section also includes an apparatus that applies a magnetic field to the sheet of paper being formed. The machine also includes a controller that causes the apparatus to apply the magnetic field in response to a signal from the sensor representative of the first characteristic. The magnetic field transforms a second characteristic of the sheet of paper. The apparatus may transform a characteristic such as water content or fiber orientation. | 11-05-2009 |
20100043992 | Process belt, method for producing paper or nonwoven and use of a process belt - Increasingly higher requirements are imposed on the quality and the speed of the production process during the manufacture of nonwovens. It is therefore an object of the invention to provide a process belt for improved nonwoven manufacture. This object is achieved with a process belt for nonwoven or paper manufacture which comprises a device for electrical charging of the process belt. | 02-25-2010 |
20100319866 | MEASURING OF WEB - Optical radiation sources functioning on different optical bands radiate on different optical bands and focus optical radiation on a region in a web surface as pulses in such a manner that illumination areas of the pulses overlap on the plane of the web. At most one optical radiation band is focused on the web from the direction of the normal. The spatial intensity distribution of at least one optical band differs from the uniform distribution and the intensity distributions of at least two different optical bands differ from one another in a predetermined manner. A camera forms still images of the web surface region on each optical radiation band. An image-processing unit determines the surface topography of the web on the basis of the images. In addition, a controller may control the paper manufacturing process on the basis of the determined surface topography. | 12-23-2010 |
20100319867 | METHOD FOR PREPARING PAPER THAT IS USEFUL IN BIOMIMETIC ELECTRO-ACTIVE PAPER ACTUATORS - This invention relates to biomimetic electro-active paper actuators which are ultra lightweight, have a large deformation feature, are operated with low power consumption, are remotely driven by microwaves, and have suitable response speed, which are comprised of paper wherein micro fibrils of cellulose are arranged in a predetermined direction, electrodes which are deposited on both sides of the paper, a film rectenna which receives an electric field from outside and converts it into direct power, and a PAD logic circuit (power allocation & distribution) which receives a signal of direct power and converts/controls it into power force. | 12-23-2010 |
20120285647 | Marking Paper Products - Methods of marking paper products and marked paper products are provided. Some methods include irradiating the paper product to alter the functionalization of the paper. | 11-15-2012 |
20130000858 | METHOD AND A REACTOR FOR MIXING ONE OR MORE CHEMICALS INTO A PROCESS LIQUID FLOW - A method for mixing a chemical into a process liquid including: injecting the chemical into the process liquid flowing through a flow pipe; forming reaction products by a reaction involving the chemical occurring in the process flow; applying an electric field or magnetic field to a region of the flow pipe adjacent to the reaction occurring in the process flow, and suppressing the precipitation of the chemical or the reaction products on the surfaces of the pipe due to the electric or magnetic field. | 01-03-2013 |
20130213597 | METHOD AND APPARATUS FOR FORMING AN ARTICLE FROM PULPED MATERIAL - Method and apparatus for moulding an article from pulp material, in which the article is moulded on the surface of a mould tool, the article is pressed and the pressed article is dried, using heated gas or superheated steam that is passed through the pressed article or using microwaves, in which the pressed article is retained on a tool during the drying. The tool may be the mould tool or a different tool. | 08-22-2013 |
