Problems solved by technology

As mentioned in EP 2 314 762 A1, these embodiments have the disadvantage that the first piping line then has less presence in the first textile fabric layer, ie a larger recess is produced at any piping point , resulting in a more uneven surface on the paper side, which in the paper results in poorer paper fiber retention and a tendency to produce marks

Embodiment Construction

[0024] figure 1 The papermaker's fabric 1 shown in has a first woven fabric layer 2 and a second woven fabric layer 3 . The two textile fabric layers 2, 3 are laid on top of each other. The outer side of the first woven fabric layer 2 forms the paper side 4 and the outer side of the second woven fabric layer 3 forms the machine side 5 of the papermaking fabric 1 .

[0025] The first textile fabric layer 2 consists of first longitudinal threads (indicated by 6 for example) extending in the direction of travel of the papermaking fabric 1 and first transverse threads 7, 8 extending transversely to the first longitudinal threads, the first longitudinal threads and Both second transverse threads have a circular cross-section. The first transverse lines include the transverse binding lines 7 and the first transverse lines 8 which are not the transverse binding lines 7 . These two kinds of threads 7 , 8 alternate with each other in the direction of the first longitudinal thread 6 ...

Abstract

The invention relates to a fabric (1, 21) having a first woven fabric layer (2) forming a paper side and made of first threads (6, 7, 8), and a second woven fabric layer (3) made of second threads (9, 10), the two woven fabric layers (2, 3) being connected by binder threads (7) belonging to the first woven fabric layer (2) such that at binding points (13) the respective binder thread (7) binds with one first thread (6a) on the paper side, then changes to the second woven fabric layer (3) and binds with at least two second threads (9a, 9b) and then returns to the first woven fabric layer (2) again and binds with a first thread (6b) on the paper side, wherein at binding points (13) only one first thread (6c) is not bound by the said binder thread (7).

Description

technical field [0001] The present invention relates to a papermaker's fabric which can be used in particular as a forming fabric in the forming section of a paper machine, the papermaker's fabric having a first woven fabric layer and a second woven fabric layer, the first woven fabric layer on its The paper side is formed on the outside and is made of interwoven first threads, the second textile fabric layer forms the machine side on its outside and is made of interwoven second threads, the two textile fabric layers are formed by belonging to the first textile fabric The inherent binding lines of the layers are interconnected such that at the binding point the respective binding line is bound with the first line extending transversely to the binding line by passing over its paper side, then changes to the second woven fabric layer and passes over its paper side Passing on the machine side with at least two adjacent second lines extending transversely to the binding line, and ...
