Abstract (en)
[origin: WO2020015915A1] The invention relates to clothing for a machine for producing a fibrous web, in particular a paper, board or tissue web, the clothing comprising a substrate (20). The substrate has a top side (22), an underside (24), two side edges and a useful region between the two side edges. The useful region has a plurality of through-channels (30), which connect the top side (22) to the underside (24) of the substrate (20). The inner surface (32) of at least one through-channel (30), preferably of the majority of all the through-channels (30), more preferably of all the through-channels (30) in the useful region of the substrate (20), has a mean roughness depth (Rz) that is greater than 4 µm, preferably greater than 6 µm, more preferably greater than 8 µm. The invention further relates to a method for producing clothing of this type by means of a laser.
