A covering for use with a paper, cardboard, tissue or fibrous web making machine, the covering including a plurality of films laminated together, the films including a polymer material. The plurality of films each having a plurality of perforations penetrating a thickness of each film. The perforations being configured to form drainage channels through the covering. At least one of the films having perforations had filler particulates distributed through the polymer material of the film. The filler particulates having been substantially removed from the polymer material to form the perforations in the films.

This invention relates to a paper machine mesh, in particular a forming mesh, including an upper fabric layer, whose outer side forms a paper side, and a lower fabric layer, whose outer side forms a machine side of the paper machine mesh, and tie threads extending in the longitudinal thread direction, which connect the upper fabric layer and the lower fabric layer to each other, wherein the upper fabric layer is formed at least by the tie threads and, woven therewith, upper transverse threads extending transverse to the tie threads, wherein the lower fabric layer is formed at least by the tie threads and, woven therewith, lower transverse threads extending transverse to the tie threads, wherein each lower transverse thread is held respectively by several tie threads in that each of these tie threads continually crosses the respective lower transverse thread on the outer side of the lower fabric layer, and wherein at least some of the tie threads holding a respective lower transverse thread are separated from each other by at least one tie thread not holding the lower transverse thread in that the lower transverse thread continually crosses the non-holding tie thread on the outer side of the lower fabric layer. The mesh also includes several lower transverse threads for which an identical number of non-holding tie threads is always arranged respectively between consecutive tie threads respectively holding the lower transverse thread.

This invention relates to a paper machine covering such as a mesh, in particular forming mesh, having an upper fabric layer which is repeated in upper repeats and whose outer side forms the paper side of the mesh, having a lower fabric layer whose outer side forms the machine side of the mesh, and having tie threads arranged in groups and extending in the longitudinal thread direction, which connect the upper fabric layer and the lower fabric layer to each other, wherein the upper fabric layer is formed at least by the tie threads and, woven therewith, upper transverse threads extending transverse to the tie threads, in that the tie threads of each group alternate in sections when weaving with the upper transverse threads in the longitudinal thread direction, thus jointly creating an upper longitudinal thread run which is repeated over the length of the upper repeat in the longitudinal thread direction, wherein the lower fabric layer is formed at least by the tie threads and, woven therewith, lower transverse threads extending transverse to the tie threads, wherein the tie threads of each group cross when switching from weaving with the upper transverse threads to weaving with the lower transverse threads and vice versa, thus forming intersections. The tie threads of at least one group are woven with the upper and lower transverse threads such that at least two consecutive intersections are arranged over the length of the upper repeat in the longitudinal thread direction.
