Abstract
A paper machine clothing has a plurality of through-channels formed in a usable region. The through-channels extend through the substrate to connect the upper and lower sides. The through-channels are non-cylindrical with a cross-sectional area becoming smaller along a thickness direction of the substrate from the upper side to a middle region of the substrate. 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, wherein the upper rims of both neighboring through-channels have at least three common local maxima, including two outer common local maxima and one intermediate common local maximum that is located between the two outer common local maxima. There is also described a method of producing such a paper machine clothing.
