Embodiment Construction

[0038] figure 1In order to better understand the invention, a highly schematic schematic diagram of a finished stretch fabric 1 constructed according to the invention is first shown. It should be noted that here, for reasons of clarity, only the basic structure 3 is shown and no other additional components are shown.

[0039] The stretch fabric 1 here has a plurality of strips 2 which are arranged next to each other in the cross-machine direction (hereinafter referred to as CMD) and connected to one another. The individual strips 2 are connected to each other by seam regions 4 .

[0040] figure 2 A schematic diagram of a single strip 2 showing the basic structure 3 . The basic structure 3 can be embodied or produced in different ways here. On the one hand, a plain weave structure with woven seam loops 5 can be realized at the lateral edges 6 . Such structures can be produced in large widths on conventional textile machines.

[0041] Furthermore, it is possible and conce...

Abstract

A fabric (1) for use in particular in the press section of a machine for producing fibrous webs, such as paper, board or tissue webs, comprising a basic structure (3) and at least one A layer of staple fibers arranged on and connected to the basic structure (3). The web (1) consists of a plurality of strips (2) in the form of a sheet with a basic structure (3) part and at least one staple fiber layer part, wherein the strips (2) are placed on two sides of each other. There are seam rings (5) on the opposite edge (6), the seam rings are respectively connected with the seam rings (5) of the edges (6) of the adjacent strip (2), and wherein there is a seam The edges (6) of the sewing loops (5) are oriented in the transverse machine direction of the stretched web (1).

Description

technical field [0001] The invention relates to a stretched wire, which is used in particular in the press section of a machine for producing fibrous webs, such as paper, cardboard or tissue webs, and also to a Methods. Background technique [0002] Stretched wires exist in paper machines in various forms. Depending on the location, the stretcher wires have different tasks, in addition to supporting and guiding the paper web, they are also used, inter alia, for dewatering. The water which is present in the paper web to a gradually decreasing extent as it passes continuously through the machine must be drained in a suitable manner, without damaging the paper web here or causing the paper web to dewater due to mechanical or hydraulic pressure during dewatering. process to generate marks. [0003] Especially in the press section, gentle dewatering is of importance, since here provision is already made for the smoothing of the paper web. After the initial dewatering in the f...
