Embodiment Construction

[0027] A preferred embodiment of the present invention as shown in Fig. 1 will now be described with respect to the manufacture of a shoe press belt for a paper machine and its manufacturing procedure. However, it should be noted that the present invention is also suitable for use in the manufacture of paper machine rolls or roll covers.

[0028] With continued reference to FIG. 1 , the belt may comprise a base structure or substrate of any conventional belt base substrate known in the art, including wovens, nonwovens, spiral connections, arrays of MD or CD yarns, knitted fabrics, Extruded mesh, and helically wound strips of woven and nonwoven materials. These substrates may comprise any type of yarn used to make papermaker's clothing, such as monofilament yarns, plied monofilament yarns, multifilament yarns, and plied multifilament yarns. These yarns may be extruded from any polymeric resinous material available to one of ordinary skill in the art for this purpose. Thus, re...

Abstract

The present invention is grooved belts, or surface rollers as applicable, and methods of making these belts or rollers, comprising disposing a chemically reactive material on a partially completed belt surface, and depositing an elastomeric material on the surface of the belt to react therewith and to Form bonds on chemically reactive materials to generate patterns. The grooves are generated, for example, with an arrangement of elastomeric material. Grooves are formed without machining, and the resulting belt has a smooth, uniform surface without cuts or cracks.

Description

technical field [0001] The present invention relates to the field of papermaking and, in particular, to a method for the manufacture of grooved belts used in papermaking machines and papermaking processes, or, depending on the application, roll cover. The present invention involves utilizing a ribbon arrangement to create grooves without machining the belt surface. Background technique [0002] During papermaking, a web of cellulose fibers is formed in the forming section of a paper machine by depositing a fiber slurry, which is an aqueous dispersion of cellulose fibers, onto a moving forming fabric. Most of the water in the slurry is drained through the forming fabric, while the cellulosic web remains on the surface of the forming fabric. [0003] From the forming section, the newly formed cellulose web enters the press section, which consists of a series of press nips. A web of cellulosic fibers is supported by a press fabric, or typically between two such press fabrics,...
