20100000697 | DRYER FABRIC FOR A CONDENSATION DRYING APPARATUS - A dryer fabric for a condensation drying apparatus in a machine which produces and/or processes a web material, such as paper, cardboard or tissue, includes a base structure which essentially provides the dimensional stability of the fabric and which consists of polyester and/or PCTA and/or PCT and/or PEEK and/or PPS and/or thread material which includes PA with high temperature stability; a fibrous nonwoven layer located on the basic structure, which essentially provides the water absorption capacity of the fabric and which provides the dryer fabric with a web material contact side on its outside, facing away from the basic structure, whereby the fibrous nonwovens layer comprises a first polymer material located at least in the area of the outside and whereby the fibrous nonwovens layer is compressed and smoothed in the area of the outside which provides the web material contact side through means of hot-calendering above the melting temperature of the first polymer material. | 01-07-2010 |
20100070065 | METHOD TO PROVIDE A PROGNOSIS OF THE SURFACE TOPOGRAPHY OF TISSUE PAPER - A method of surface topography prognosis for a tissue paper which is to be produced in a manufacturing process by utilizing a structured fabric and into which a structure is embossed by way of the fabric, the surface topography of at least one structured fabric which is already used in the production process is plotted by way of a sensor. Originating from the surface topography of the already utilized structured fabric, the surface topography of the tissue paper is simulated through data processing, through a simulation of the paper production process. The algorithm used for the simulation is calibrated with the aid of a comparison of the simulated surface topography of the tissue paper with the surface topography of the actual tissue paper produced with the structured fabric, which is already being utilized in the production process. Originating from the surface topography of a respective additional structured fabric the simulation of the surface topography of the tissue paper is subsequently conducted by utilizing the calibrated algorithm in order to provide a prognosis of the tissue paper's surface topography that can be expected. | 03-18-2010 |
20100133071 | TRANSFER BELT - A transfer belt for carrying a fibrous web and a papermaking or similar machine. The transfer belt consists of a supporting substrate of a polymer foam and a reinforcement layer of aramid or glass fiber in either fabric or layer foam and a release layer that overlies and is bonded to the supporting substrate. The release layer is formed from a material promoting release of the fibrous web. The release layer may be selected from a variety of materials. The layers each contribute their own function to the operation of the belt to provide superior performance. | 06-03-2010 |
20100136286 | COVERING FOR PAPER MACHINE - A covering for use with a paper, cardboard, tissue or fibrous web making machine, the covering including a plurality of films laminated together, the films including a polymer material. The plurality of films each having a plurality of perforations penetrating a thickness of each film. The perforations being configured to form drainage channels through the covering. At least one of the films having perforations had filler particulates distributed through the polymer material of the film. The filler particulates having been substantially removed from the polymer material to form the perforations in the films. | 06-03-2010 |
20100196620 | PROCESS FOR COATING A BELT, IN PARTICULAR THE FABRIC OF A PAPER MACHINE - The present invention relates to a method of coating a technical textile belt or fabric for a machine to produce a fibrous web of material, for example paper, cardboard, or tissue, which includes the step of i) providing a belt, whereby a coating is applied onto one side of belt; ii) providing of an applicator device, with which a liquid medium can be applied onto one side of belt without actually coming in contact with the belt; iii) applying the liquid medium onto one side of the belt; and iv) causing the liquid medium to bond and develop in order to allow the formation of a solid coating covering on the side of the belt and/or the inner structure covering at least a portion of the side of the belt. The method according to the present further provides that in invention step iii), the applicator device, follows a previously established raster in applying pre-determined quantities of the coating medium onto a plurality of locations, located within at least one region on the side of the belt. The coating medium and the material and/or the structure of the belt are further selected in such a way that the coating medium will spread out on the surface of the side of the belt and/or from the surface of the side into the interior of the structure of the belt. | 08-05-2010 |
20100252217 | PAPER MACHINE CLOTHING WITH EDGE REINFORCEMENT - The invention relates to a clothing for a web-processing machine, in particular a tissue machine, including a flat basic structure with an upper side and a lower side, and with a coating which is applied to the upper side and/or lower side and includes at least one polymer material. At least one polymer material is a polyurea, in particular an elastomer polyurea. | 10-07-2010 |
20110159762 | PAPER MACHINE CLOTHING WITH MONOFILAMENTS HAVING CARBON NANOTUBES - A PMC fabric yarn for use in a PMC fabric. The PMC fabric yarn has a composition which is a mixture of between 90% and 99.8% PET, with a remainder of said composition being between 0.2% and 10% CNT. The composition of the yarns has a relative elongation at 15.75 cN/tex which is between approximately 5% and 20% less than the PET, and an abrasion resistance which is between approximately 50% and 500% greater than the PET. | 06-30-2011 |
20130153167 | PERFORATED FILM CLOTHING - A fabric for a papermaking machine is configured as a belt, the two side edges of which are configured in each case as closed lines. Furthermore, the belt is formed in one layer from a solid material and has pores which form passages between the two surfaces of the belt. The belt has regions with a width of approximately 400 micrometers (μm) or less. These regions extend in the longitudinal direction over the entire circumference of the belt, transversely with respect to the side edges, and include no pores formed therein. | 06-20-2013 |
20130345035 | PAPER MACHINE ROLLER WITH FIBER BRAGG SENSORS - A roller for use in paper machines includes a roller core, a roller covering surrounding the roller core, and at least one optical waveguide having a plurality of fiber Bragg gratings. The at least one optical waveguide is either arranged between the roller core and the roller covering or is embedded in the roller covering. Sections of the at least one optical waveguide which each contain a fiber Bragg grating alternate with sections of the at least one optical waveguide which are free of fiber Bragg gratings in the longitudinal direction of the optical waveguide.
