Embodiment Construction

[0033] Referring now to these drawings, figure 1 is a schematic top view showing the method for making the press fabric of the present invention. The method can be realized by means of a device 10, which includes a first roller 12 and a second roller 14 that are parallel to each other and can rotate along the direction indicated by the arrow. The laminated structure 16 in ribbon form is wound from a stock roll 18 onto the first roll 12 and the second roll 14 in a continuous spiral. It should be understood that when the laminated structure 16 is being wound on the drums 12, 14, the storage roll 18 must travel along the second drum 14 (towards figure 1 to the right of the ) to move.

[0034] There is a certain distance D between the first cylinder 12 and the second cylinder 14. The distance D is determined according to the total length C required by the processed press fabric, and the total length C is to surround the press fabric in the form of an endless loop. The fabric ...

Abstract

A press fabric is manufactured by spirally winding a strip in a plurality of non-overlapping abutting turns, and by joining each turn of the strip to that previously wound. The strip is itself a laminated structure having at least two layers attached to one another. The strip is manufactured in considerable lengths for subsequent use in manufacturing press fabrics in any length and width dimension.

Description

technical field [0001] The present invention relates to papermaking technology. In particular, the present invention relates to press fabrics for use in press sections on papermaking machines. Background technique [0002] In the papermaking process, a cellulosic web is formed by depositing a layer of fiber slurry, an aqueous dispersion of cellulosic fibers, onto a moving forming fabric in the forming section of a paper machine. A large amount of water is drained from the pulp through the forming fabric so that the cellulosic web is left on the surface of the forming fabric. [0003] The newly formed cellulosic web proceeds from the forming section to a press section comprising a series of nips. The cellulosic web passes through a nip supported by press fabrics or, as is often the case, the nip is located between two press fabrics. In the nip, the cellulose web is subjected to pressure, which forces water out of it, and this pressure causes the cellulose fibers on the web...
