Abstract
A paper machine clothing has a substrate with an upper side, a lower side, two lateral edges and a usable region between the two lateral edges. The usable region is formed with a multiplicity of through-channels that extend through the substrate from the upper side to the lower side. The through-channels are non-cylindrical with a cross sectional area becoming smaller when going in a thickness direction of the substrate from the upper side to a middle region of the substrate between the upper side and the lower side. An upper rim of at least one of the plurality of through-channels directly contacts an upper rim of at least one other neighboring through-channel of the plurality of through-channels. There is also described a method of producing such a paper machine clothing.
