Embodiment Construction

[0059] Preferred embodiments of the present invention will be described in detail below with reference to the drawings.

[0060] figure 1 It is a perspective view which shows an example of the felt for papermaking which concerns on one Embodiment of this invention. This felt 1 has a base fabric layer 2 and a tie layer 3 integrally formed with the base fabric layer 2 . The base fabric layer 2 is a belt-shaped body 10 having a plurality of bottom warp threads 13, a plurality of bottom weft threads 14, a first side edge 11, and a second side edge 12, and the width Ws is smaller than the width Wf of the felt 1 for papermaking. The first side edge 11 and the second side edge 12 are spirally wound adjacent to each other, and the side edges (adjacent first side edge 11 and second side edge 12 ) are joined together. Also, only a part of the bottom warps 13 and the bottom wefts 14 are drawn in the figure.

[0061] Needless to say, the bottom warp 13 of the strip 10 and the direction...

Abstract

The invention provides a felt for papermaking and a manufacturing method thereof. The felt for papermaking has a base cloth layer and at least one tie layer integrally formed with the base cloth layer, and the base cloth layer has at least one layer having a plurality of bottom warp threads, a plurality of bottom weft threads, a first side edge and a bottom weft thread. On the second side, a strip-shaped body having a width smaller than that of the felt for papermaking is spirally wound, and the first side and the second side are adjacent to each other, and the side edges are joined together to form a layer , a plurality of marks are arranged at equal intervals in the longitudinal direction of the strip.

Description

technical field [0001] The present invention relates to a felt for papermaking (hereinafter also simply referred to as "felt") used in a paper machine and a method for producing the same. Background technique [0002] A paper machine for removing moisture from paper raw materials generally includes a wire section, a press section, and a dryer section. The wire section, the press section, and the dryer section are arranged in this order along the conveying direction of the wet paper. The wet paper has a certain width in the direction (CMD: Cross Machine Direction) perpendicular to the traveling direction (MD: Machine Direction) of the paper machine, and moves in the paper machine in a belt shape, and is gradually handed over to each The papermaking tools in the screen section, press section, and dryer section are dehydrated while being conveyed, and finally dried in the dryer section. [0003] The press device arranged in the press section includes a plurality of press devi...
