Problems solved by technology

Due to the loss of filler, it is very difficult to obtain uniform physical characteristics of the conveyor belt, and sufficient durability
Therefore, it is very difficult to manufacture a wet paper web transfer belt suitable for long-term use

example 1

[0065] according to the present invention has Figure 5 The wet paper web transfer belt of the structure shown was manufactured according to the following procedure.

[0066] Endless double fabric obtained by weaving longitudinal and transverse threads of Nylon-6 so that the basis weight of the double fabric is 600 g / m 2 . Artificial fibers including nylon-6 and having an average fineness of 20 dtex were intertwined with the outer surface of the endless fabric by needling to form an integral body. The basis weight of the artificial fiber layer is 200g / m 2 .

[0067] The fabric is then turned over, and the side that was not previously intertwined with man-made fibers becomes a new outer surface. In order to form the flocking layer, man-made fibers with an average fineness of 20 dtex are intertwined with the new outer surface by needling to form a whole, so that the basis weight of man-made fibers is 200 g / m 2 . In this way, it is formed with a basis weight of 200g / m on bo...

example 2

[0071] Another wet paper web transfer belt according to the present invention was manufactured as follows.

[0072] An endless double fabric is obtained by weaving longitudinal and transverse threads of nylon-6 so that the basis weight of the double fabric is 600 g / m 2 . Man-made fibers including nylon-6 and having an average fineness of 20 dtex were integrally intertwined with the outer surface of the endless fabric by needling. The basis weight of the artificial fiber layer is 200g / m 2 .

[0073]The fabric is then turned over so that the side that was not previously intertwined with man-made fibers becomes a new outer surface. Multiple layers of BIOSAFE man-made fibers with an average fineness of 3.3 dtex, an average length of 76 mm, and a porosity of 60% are intertwined with the new outer surface of the fabric by needling to form a whole, so that the basis weight of the final man-made fiber layer is 300 g / m 2 . In this way, a basis weight of 200g / m can be obtained for ...

Abstract

In a wet paper web transfer belt (10), the wet paper web side layer is formed by a high molecular weight elastic section (50) containing porous bodies (20) which are exposed at, or protrude from the web-contacting surface. The porous bodies (20) are anchored in the resin and wear at about the same rate way as the surrounding resin. Therefore, the distribution of the porous bodies does not vary significantly as a result of abrasion. This transfer belt can transport an attached wet paper web, and release the web smoothly to a next stage in the papermaking process, over a long period of use.

Description

technical field [0001] The invention relates to a wet paper web transfer belt, in particular to a transfer belt for high-speed transfer of wet paper web. Background technique [0002] In recent years, in order to achieve high-speed operation of paper machines, "closed traction" paper machines have been developed. Compared to traditional open draw machines, where the wet paper web is conveyed without support, and closed draw machines, where the wet paper web is supported throughout the papermaking process. The closed traction structure solves various problems encountered in the operation of the open tractor, such as paper deviation. Thus, high-speed production can be realized. [0003] Such as Figure 9 As shown, in a typical closed draw paper machine, the wet paper web WW conveyed from the right to the left in the figure shown by the dotted line is supported by the press felts PF1 and PF2, the wet paper web transfer belt TB, and the dry fabric DF . The press felts PF1 an...
