Abstract
A substrate of a paper machine clothing has a usable region formed with through-channels that are non-cylindrical with a cross-sectional area becoming smaller from an upper side to a middle region of the substrate. An upper rim of at least one of the through-channels directly contacts an upper rim of at least one neighboring through-channel and the upper rims have common local maximum. A sectional plane parallel to the thickness direction of the substrate defines an intersecting line with a sidewall of a neighboring through-channel. The intersecting line has a convexly shaped first portion, a concavely shaped second portion, and a third portion that is again convexly shaped going from the at least one common local maximum toward the middle region of the substrate. There is also described a method of producing such a paper machine clothing.
