20080248279 | PAPER MACHINE FABRICS - A composite paper machine fabric substrate of a base and batt formed from polyamide is reinforced by a polymer having a glass transition temperature (TG) of −40 to 15° C. that is dispersed at below the face side surface of the fabric substrate to mechanically bond to the substrate. The polymer is thermoplastic enabling an improvement in flexibility and overall wear while at the same time permitting porosity necessary for proper drying of paper. | 10-09-2008 |
20080289716 | LOW TENSILE CREEP BELT - An endless fabric belt subjected to a substantial running tension. The belt has an endless woven fabric formed from a plurality of MD (machine direction) ultra high molecular weight polymer strands approaching zero creep at high tensile loads. A plurality of CMD (cross machine direction) strands are interwoven with the MD strands. The plurality of MD strands have first and second ends spliced to one another to form an endless belt, the splices forming a significant linear MD overlap of about 30 cm with each other. | 11-27-2008 |
20090084460 | PRESS FABRIC TREATMENT - A fabric for use in a papermaking machine, the fabric including a first end portion of the fabric having a first flexibility, and a second end portion of the fabric having a second flexibility. At least one of the first end portion and the second end portion is treated with an agent to reduce the flexibility associated therewith. The first end portion and the second end portion are coupled together. The agent is substantially removed from the first end portion and the second end portion. The reduced flexibility of the first end portion and/or the said second end portion define a stiffness that is substantially unaffected by a humid environment. | 04-02-2009 |

20090186544 | FORMING FABRIC FOR A MACHINE FOR THE PRODUCTION OF WEB MATERIAL AND METHOD TO PRODUCE SAID FORMING FABRIC - A belt for a machine for the production of web material, especially paper or cardboard, including a carrying structure and, on one web material contact side of the carrying structure, a fibrous material with polymeric material contained therein. A bulk of the polymeric material is provided in a volumetric area of the fibrous material which is close to a web material contact surface. | 07-23-2009 |
20090186546 | COMPOSITE PRESS FABRIC - A press fabric for a machine for the production of web material, especially paper or cardboard, including a carrying structure and a plurality of layers on one web material contact side of the carrying structure, whereby polymeric material is contained in at least one of the layers of fibrous material. | 07-23-2009 |
20090203277 | CLOTHING FOR USE ON MACHINES FOR PRODUCING MATERIAL WEBS IN THE FORM OF PAPER WEBS, PAPERBOARD WEBS OR TISSUE WEBS AND METHODS FOR MANUFACTURING A PAPER MACHINE CLOTHING - A clothing and method for producing the clothing, for use on machines for producing material webs in the form of paper webs, paperboard webs or tissue webs, in particular a press belt or transfer belt with a porous composite structure, comprising at least one layer, which forms the surface supporting the material web, and particulate polymer material, whereby, after thermal activation, the particulate polymer material is partly melted and bonded to the structure forming the layer so that said structure is partly impregnated and voids in the structure are partly filled. The clothing is characterized in that the particulate material is partially differently distributed in the region of the surface supporting the material web over the width direction of the clothing. | 08-13-2009 |
20090211722 | BELT AND METHOD OF MAKING A BELT FOR A PAPER MAKING MACHINE - Belt and method of making a belt for a paper making machine. The belt includes a flat woven material having a top side surface and a bottom side surface and two terminal ends separated in a machine direction. Folds formed in the flat woven material are separated in the machine direction, so that the two terminal ends are located under the bottom side surface. Seam loops are located at the folds, and the two terminal ends one of are arranged adjacent each other and overlap each other in a region offset from a center between the folds. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way. | 08-27-2009 |
20090214822 | MULTILAYERED LAMINATED FABRIC WITH SINGLE SEAM - A system and method of for creating a multilayered laminated fabric having a single seam. The system includes a top base layer having a seam and a roll side base layer having a first end and a second end arranged in a non-contacting manner to form a gap. The method includes joining a top base layer and a roll side base layer together and seaming the top base layer, wherein a gap is formed in the roll side base layer. | 08-27-2009 |
20100055336 | METHOD OF MAKING POLYMER PARTICLES MIXED WITH FIBERS, AND PRODUCTS SUCH AS PRESS FABRICS MADE THEREFROM - A mixture contains polymer particles along with solids or fibers that can be utilized in press felts (or fabrics) for the press section of a papermaking machine and a method of making the mixtures are described. Methods of making the mixture, press felts or press fabrics are also provided. | 03-04-2010 |
20100078142 | METHOD AND JOINING ASSEMBLY FOR JOINING ENDS OF FABRIC IN A PAPER MACHINE - A fabric for use in a paper machine includes a pair of ends connected together in a join area to make an endless loop of fabric, the join area having a plurality of perforations extending therethrough. | 04-01-2010 |
20100159760 | PRESS FABRIC FOR A MACHINE FOR THE PRODUCTION OF WEB MATERIAL AND METHOD TO PRODUCE SAID PRESS FABRIC - A press fabric for a machine for the production of web material, especially paper or cardboard, includes a carrying structure and at least one layer of fibrous material on one web material contact side of the carrying structure, whereby at least some of the fibers of the at least one layer of fibrous material are coated at least partially with a film of a first polymeric material and whereby a permeable composite structure is formed by a second polymeric material in the at least one fibrous layer, in that the hollow spaces which are formed between fibers of the at least one fibrous layer are filled partially with the second polymeric material. | 06-24-2010 |
20100170652 | PRESS FELT - The present invention relates to a press felt having a first surface provided by a nonwoven structure and a second surface opposite the first surface, as well as a load absorbing base structure which is bonded with the nonwoven structure and is arranged between the first and the second surface. The press felt according to the present invention further includes particulate polymer material which is penetrated into the nonwoven structure from the first surface in sections in the direction of the second surface and which is adhered to the fibers of the nonwoven structure in a manner that the press felt has a permeability of at least 5 cfm, for example, at least 10 cfm. The present invention is characterized in that at least one filter layer is arranged in the nonwoven structure or at the barrier surface between the nonwoven structure and the base structure which is permeable for fluid and is substantially impermeable for polymer material from, for example, a predetermined particle size on. | 07-08-2010 |
20100314066 | PRESS FABRIC SEAM AREA - A pinseam press fabric is smoothed in the area of the seam by depositing polyurethane particles having a size of about 1 to 500 micrometers across the seam of the felt defined by the ends of the fabric. The polyurethane particles are drawn into the seam end by the application of a vacuum. Once the particles are deposited, the fabric is heated so that the polyurethane particles melt to form a polymeric matrix. | 12-16-2010 |
