Abstract
The machine felt includes an insert having two sides and two ends, a layer of aligned longitudinal threads enclosing the two sides and two ends of the insert and coupling eyes formed by the layer of aligned longitudinal threads enclosing the two ends of the insert. The insert is enclosed by folding the layer of aligned longitudinal threads over the insert or by placing the insert within the layer of aligned longitudinal threads having a cylindrical configuration.
