Embodiment Construction

[0024] figure 1 and figure 2 The illustrated wet paper web transfer belt 10 includes a substrate 30 , a wet paper web side layer 11 , and a machine side layer 12 . The wet paper web side layer 11 is formed of the high molecular weight elastic portion 50 and the fibrous body 20 . The fibrous body 20 is hydrophilic, and part of the fibrous body 20 is exposed on the surface of the high molecular weight elastic portion 50 . The terms "exposed" and "exposed" refer to a situation in which the fibers 20 appear on the surface of the high molecular weight elastic portion 50 regardless of whether the fibers of the fiber body 20 protrude from the surface of the high molecular weight elastic portion.

[0025] At least part of the fibrous body exposed on the surface of the high molecular weight elastic portion 50 has water absorption. The terms "hydrophilic" and "hydrophilic" refer to the property of a fiber body to attach, and / or retain water. According to a particular embodiment, t...

Abstract

A wet paper web transfer belt 10 comprises a base body 30, a wet paper web side layer 11 and a machine side layer 12. The wet paper web side layer 11 is formed by a high molecular weight elastic section 50 and a fiber body 20. The fiber body 20 is hydrophilic, and at least a part of the fiber body 20 is exposed on the surface of the high molecular weight elastic section 50. The hydrophilic fiber body 20 exposed on the surface of the wet paper web side layer 11 holds water from a wet paper web and therefore, attachment of the wet paper web to the transfer belt, and the smoothness of removal the wet paper web from the transfer belt, are both improved without impairing the durability of the transfer belt.

Description

technical field [0001] The present invention relates to wet paper web transfer belts, hereinafter also referred to as "belts", and in particular to a belt for high speed transfer of wet paper webs. Background technique [0002] Recently, "closed draw" paper machines have been developed in order to obtain improved operating speeds. Closed draw paper machines lack open draw, that is, parts of the wet paper web are conveyed without support. The closed draw structure can avoid various problems faced by open draw paper machines, such as sheet deviation. Thus, an improved production speed can be obtained. [0003] Such as Figure 9 As shown, in a typical closed draw paper machine, the wet paper web WW represented by the dotted line is sequentially supported by press felts PF1 and PF2, wet paper web transfer belt TB, and dry fabric DF, and is conveyed from right to left. Therefore, there are no unsupported sections of the wet web in a closed draw paper machine. The press felts ...
