Papermachine fabric

Abstract

The invention relates to a papermachine fabric having a batt structure extending over the entire width of the fabric, the batt structure comprising at least one ultrathin elongated fiber batt which extends over a part width of the fabric and has a thickness of 0.3 mm or less.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] The present application claims priority under 35 U.S.C. § 119 of German Patent Application No. 10 2005 023 390.2 filed on 20 May 2005, the disclosures of which is expressly incorporated by reference herein in its entirety. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The invention relates to a papermachine fabric for use in a paper, board or tissue machine. [0004] 2. Description of Background [0005] In order to reduce the production costs for papermachine fabrics, the aim of current developments is often to provide modularly constructed papermachine fabrics. [0006] One possibility for the modular construction of papermachine fabrics consists in providing carrier or reinforcing structures which are built up from basic elements that are prefabricated and joined to one another, such as threads and / or flat structures such as films or the like. [0007] In the production of papermachine fabrics, use is currently made of ...

AI Technical Summary

Benefits of technology

[0009] The object of the present invention is to propose a papermachine fabric having a batt structure whose properties can be adapted simply to the respective customer-specific requirements and which, moreover, can be produced more cost-effectively than the papermachine fabrics with a batt structure known from the prior art.

[0011] As a result of providing at least one ultrathin batt section which extends over part of the width of the batt structure and has a thickness of 0.3 mm or less, it is possible to build up the batt structure from one or more of the ultrathin and cost-effectively prefabricated batt sections in accordance with the specific requirements on the fabric, irrespective of its overall thickness and overall width.

[0018] A plurality of such ultrathin fiber batts can then be joined flatly to one another in order to form at least one part of the batt structure. In this way, the batt structure can be built up simply and cost-effectively from the prefabricated ultrathin batt sections virtually in any desired thickness graduation and with virtually any desired properties in accordance with the customer requirements.

[0025] In this case, it is both possible for the ultrathin batt sections of an ultrathin fiber batt to have the same thickness or for at least one of the ultrathin batt sections of the ultrathin fiber batt to have a different thickness than the remaining ultrathin batt sections of the ultrathin fiber batt. In the last-named case, it is also conceivable for a plurality of ultrathin batt sections to be arranged above one another and jointly to have a height which corresponds to the height of the adjacent ultrathin batt sections of the same ultrathin fiber batt adjacent to the former. In this way, it is possible to form an ultrathin fiber batt having a uniform height.

Problems solved by technology

As a result of using the relatively thick fiber batts, limits are placed on the variability in the production of the batt structures.

In the case of the known fiber batts, this often requires individual production of the fiber batts specifically for the respective customer requirements, which often makes the costs for the production of such fabrics expensive.
