Press belt

FIELD: paper. ^ SUBSTANCE: press belt has closed circuit and is made of elastomer. Belt has internal and external surface and three layers of reinforcing threads installed inside elastomer material. External layer of threads is formed by longitudinal reinforcing threads of press belt that are adjacent in transverse direction. Material and/or structure of external layer reinforcing threads are thus much more flexible compared to material and/or structure of reinforcing threads of internal layer that in case of deformation they absorb more energy and are restored after deformation slower than threads of internal layer of threads. ^ EFFECT: increased service life of press belt due to prevention of cracks production and spreading. ^ 9 cl, 6 dwg РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) 2 360 058 (13) C2 (51) МПК D21F 7/08 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ, ПАТЕНТАМ И ТОВАРНЫМ ЗНАКАМ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (21), (22) Заявка: 2006131545/12, 02.02.2005 (24) Дата начала отсчета срока действия патента: 02.02.2005 (72) Автор(ы): ЕРМО Олли (FI), ХАГФОРС Сату (FI) (43) Дата публикации заявки: 20.03.2008 2 3 6 0 0 5 8 (45) Опубликовано: 27.06.2009 Бюл. № 18 (56) Список документов, цитированных в отчете о поиске: US 2003/0232557 A1, 18.12.2003.

Press blanket and method for producing the same

There are provided a press blanket for a pressing device intended for extracting liquid from a web passing through a press nip of a papermaking machine, and a device for producing such a press blanket. In addition to the reinforcing threads extending in the axial direction and circumferential threads arranged thereon and extending in the circumferential direction of the press blanket, the press blanket comprises a continuous fabric layer or a bandage extending in the area between the circumferen-tial threads and grooves or blind holes starting at the surface of the press blanket. The continuous fabric layer acts to prevent the propagation of fissures that may form in operation due to the high pressing forces, preferably at the bottom of the grooves as a consequence of the high notch stresses prevailing at these points. This significantly improves both the service life of the press blanket and the operating safety. The fabric tape may be spirally wound into the compound simultaneously with the production process, by pouring the elastomeric material onto a preferably cylindrical casting mold.

PRESS FOR EXTRACTING WATER FROM A PAPER PULP AND METHOD FOR PRODUCING A BELT FOR SUCH A PRESS

Method of seam closure for sheet transfer and other paper processing belts

Methods for closing a seam in a paper processing belt having a coating of polymeric resin material require the covering of the seam on the uncoated side of the belt with an encapsulating material, so that the seam will have compression properties substantially identical to those of use of the remainder of the belt. In one method, a viscous paste obtained by mixing a polymeric resin material with a blowing agent is used. Following installation of the fabric, or belt, on a paper machine by closing its pin seam with a pintle, the seam region on the non-paper side of the fabric or belt is impregnated with the viscous paste. The seam region is then heated to a temperature to activate the blowing agent and to create a foam from the paste. The foam fills voids in the seam region, and may pass out through the slit in the coating over the seam. Raising the temperature further cures the foam and may glue the slit closed. In other methods, a pre-foamed polymeric resin may be used to impregnate the seam region, or the seam region may be covered with a solid foam strip of a polymeric resin or a fibrous strip of fibrous batt material, either of which may be secured to the seam region by an adhesive. In each case, the belt so seamed may be used as a transfer belt or long nip press (LNP) belt, or in other paper processing applications.

The present invention relates to a method of making a resin impregnated endless belt structure having a textured outer surface which requires the use of a cylindrical mandrel or a pair of transport rolls, which are support structures having a textured surface. Permeable infinite base structures are located around the support structures that apply longitudinal tension to the base structures. The polymeric resin material is distributed outside of the base structure on the support structure. The polymeric resin material completely impregnates the base structure and passes through the base structure to cover the textured surface of the support structure. A layer of polymeric resin material also accumulates on the outside of the base structure. The polymeric resin material can then be cured and polished to provide a smooth, uniform surface to the layer of polymeric resin material, thereby separating the belt structure obtained from the support structure. Finally, the inside of the belt structure is inverted so that the indentation of the textured surface of the support structure is located on the outside of the belt structure, the textured surface for temporarily storing water pressed from the fibrous web in the press nip. It has a number of recesses.

The invention is characterized in that the transfer belt is substantially impermeable to liquid and comprises a layer (12) facing the fiber web and having a porosity that is adjusted in such a manner as to provide a liquid receiving volume in the layer (12).

Shoe press belt for making paper

A belt (shoe press belt) for a paper making machine, which has good ability of squeezing water from moist paper and which, during use, has reduced damage (cracks and wear) on the outer peripheral surface of the belt. The shoe press belt for making paper carries felt for receiving water squeezed from moist paper. A water discharge groove extended on the surface on the felt side is formed as an intermittent groove, and the width and depth of the water discharge groove are continuously varied in the direction of travel (MD direction) of the groove. The shape of the intermittent groove can be asymmetrical or symmetrical at the left and right with respect to the width, or can be formed to have a narrow width at the center of the groove, or can be formed so that the groove is deep at the center. Because the water discharge groove is intermittent, water discharge ability, the quality of paper, and the smoothness of the surface of moist paper are enhanced at the same time.

Shoe press belt

In a shoe press belt, in which the nip zone is narrower than the shoe width, the shearing force which normally acts on the belt at the outer boundary of the nip zone is made either weak or non-existent by forming the outer portions of the belt of less hardness than the inner, or central, portion of the belt, so that the less hard portions can be positioned directly opposite the outer boundaries of the nip zone. Alternatively, the outer portions of the belt can be made thinner than the central portion of the belt and the thinner portions positioned directly opposite to the nip zone boundaries. The shearing force applied to the belt at the nip ends of the roll is reduced or eliminated, cracking resulting from the shear force is reduced or avoided, and a belt having improved durability results.
