Abstract
A paper machine fabric that includes 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 and one forming the wear side and composed of longitudinal and crosswise yarns, the yarn 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 in the binding yarn system are arranged to form part of the layer on the paper-side surface. Each binding yarn 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.
