Problems solved by technology

[0004] Disadvantages of the known drying sieves are in particular that their edges tend to unravel due to the manufacturing process, and thus during the running time yarns slip out and the woven surface formations unravel.

Embodiment Construction

[0033] figure 1 A cover 1 is shown schematically, which can be used in particular as a drying screen in a machine for producing fibrous webs, for example paper or cardboard webs.

[0034] In the applications mentioned, woven drying screens are frequently used, as in the exemplary embodiment shown. Another embodiment can be made of helical coils, which overlap each other and are connected to each other by patch cords. Such an embodiment is not the subject of the present invention.

[0035] For clarity, figure 1 Only a part of the drying screen surface is shown as a weave of interdigitated yarns 2 , 3 . The yarns 2, 3 can be constructed in a known manner from PET, PPS, PCTA, nylon, Kevlar or similar, known and suitable materials for the application mentioned, in any desired cross-section Monofilament or multifilament.

[0036] The cover 1 is constructed in the form of a textile sheet with two edges 4 oriented in the machine direction (hereinafter referred to as MD) and two ...

Abstract

A clothing, in particular a drying screen (1), for a machine for producing a fibrous web such as a paper web or cardboard web, is designed as a textile sheet element made of yarns that cross each other substantially at right angles, which yarns are oriented substantially in a machine direction (MD) and in an machine transverse direction (CMD), wherein the sheet element has two edges (4) oriented in the machine direction (MD) and two edges (5) oriented in the machine transverse direction (CMD), and wherein the clothing (1) can be joined together in the machine to form a continuous belt by means of seam elements (6), which are formed by the MD yarns or detachably or undetachably connected to the MD yarns at the edges (5) oriented in the machine transverse direction (CMD). The clothing (1) is calendered by the input of energy only in border regions (7) that extend along the edges (4) oriented in the machine direction (MD) and / or along the edges (5) oriented in the machine transverse direction (CMD), whereby in the border regions the MD threads are welded to the CMD threads and the thickness and / or permeability of the clothing (1) is reduced.

Description

technical field [0001] The invention relates to a covering according to the preamble of claim 1 for use in a machine for producing a fibrous web, for example a paper or cardboard web. A cover means in particular a drying screen used in the drying section of a machine for producing a fibrous web. The invention also relates to a method for producing such a cover according to the preamble of claim 18 . Background technique [0002] Covers can be found at different locations on a paper or board machine and fulfill different tasks, which also include guiding and supporting the fibrous web and its dewatering. In the forming section, the forming screen is responsible for the primary dewatering, in the pressing section the fiber web is guided on the press felt through the nip in order to thereby further remove the moisture contained in the fiber web, and in the drying section The machine is transported through the machine and the fiber web is further dried thanks to the support of...
