Abstract

The invention relates to a paper machine fabric that comprises at least two separate layers that are formed of at least two separate yarn systems, one forming the paper side and composed of longitudinal and crosswise yarns (1, 2) and one forming the wear side and composed of longitudinal and crosswise yarns (3, 4), the yam systems being arranged to form structures independent of each other in the longitudinal and cross directions of the fabric. The structures are bound to each other by means of a binding yarn system, whereby the binding yarns (5) in the binding yarn system are arranged to form part of the layer on the paper-side surface. Each binding yarn (5) of the binding yarn system is arranged on the wear side to bind in the weave pattern repeat to more yarns than on the paper side.

Description

technical field

[0001] The present invention relates to a paper machine fabric comprising at least two separate layers formed from at least two separate yarn systems, wherein one yarn system forms the paper side and consists of longitudinal and transverse yarns thread, another yarn system forms the wear side and consists of longitudinal yarns and weft yarns, the yarn system is arranged to form structures independent of each other in the longitudinal and transverse directions of the fabric, and with binder yarns A system of threads binds these structures to each other, wherein the binding yarns of the system are arranged to form part of a layer on the paper side surface. Background technique

[0002] Traditional two-ply paper machine fabrics are formed from one longitudinal yarn system and two transverse yarn systems. An example of such an approach is US Patent Publication 4,041,989. Since there is only one longitudinal yarn system, the papermaking wire is thin and prone to...
