Problems solved by technology

This means that both the weft threads running in the longitudinal direction of the tape due to the circular weaving method and the warp threads perpendicular to the weft threads are made of polyamide material, since warp threads and weft threads made of polyamide material are particularly suitable for this loads that occur in such machines, although polyamide materials have relatively poor shape stability compared to other polymeric materials such as polyester

Embodiment Construction

[0022] figure 1 A tubular fabric 14 is shown, which can be produced by a circular weaving method. The segments formed by separating the longitudinal sections of the tubular fabric 14 form the belt segments 16 of the fabric belt for the machine for producing the web which will be described further below. The strip section 16 is made of warp yarns 12 and weft yarns 18 interwoven with the warp yarns. The weft threads 18 thus extend in the weft direction S in the circumferential direction, while the warp threads 12 extend in the longitudinal direction of the tubular fabric 14 or the strip section 16 . The warp direction K thus corresponds in the finished fabric strip to the transverse strip direction CMD, while the weft direction S corresponds to the strip longitudinal direction MD.

[0023] In the circular weaving method carried out by means of the circular weaving machine 10, the figure 1 The seam region 20 shown is woven into the tubular fabric. This seam area 20 thus forms...

Abstract

A fabric belt for a machine for producing web material, in particular paper or paperboard, is constructed with at least two belt segments (16, 16') which are produced by weaving on a circular loom, wherein, during weaving on a circular loom, the belt segments (16, 16') are each formed with at least one belt segment seam region (20) which extends in the warp direction (K) and joins two end regions (22, 24, 22', 24') of a respective belt segment (16, 16') to one another which lie in the weft direction (S), wherein, in the fabric belt (26), an end region (24) of a belt segment (16) is joined to an end region (22') of another belt segment (16') in a fabric belt mock-seam region (34), and an end region (22) of a belt segment (16) is connected or is to be connected releasably to an end region (24') of another belt segment (16') in a fabric belt seam region (40).

Description

technical field [0001] The invention relates to a fabric belt for the production of web material, especially paper or cardboard. Background technique [0002] Such fabric belts, which are used, for example, as so-called forming screens in paper machines, are usually equipped with endless structures. For this reason EP0573524B1 proposes to produce such a fabric belt by a circular weaving method and is made entirely of polyamide material. This means that both the weft threads running in the longitudinal direction of the tape due to the circular weaving method and the warp threads perpendicular to the weft threads are made of polyamide material, since warp threads and weft threads made of polyamide material are particularly suitable for this loads occurring in such machines, although polyamide materials have relatively poor shape stability compared to other polymeric materials such as polyester. This means that, under the loads that occur, primarily the weft threads running i...
