Abstract
A method for producing a paper machine clothing includes the following steps: a) providing a film-like substrate having an upper face and a lower face opposite the upper face; b) forming a pattern of holes in the substrate by boring a multiplicity of holes, which connect the upper face to the lower face, into the substrate by way of at least one laser light source. A bore hole strategy is applied which ensures that, in temporal sequence between the forming of a first hole and an immediately adjacent second hole in the pattern of holes, at least one further hole of the pattern of holes is formed in the substrate which is not immediately adjacent either the first hole or the second hole in the pattern of holes.

A method of producing a paper machine clothing, comprising the following steps:
- providing a film-like substrate having an upper side and a lower side opposite the upper side;
- forming a pattern of holes in the substrate by boring a multiplicity of holes connecting the upper side with the lower side into the substrate with at least one laser light source;
- in the forming step, applying a bore hole strategy which ensures that, chronologically between an introduction of a first hole and a second hole that is immediately adjacent the first hole in the pattern of holes, at least one further hole of the pattern of holes is introduced into the substrate which is not immediately adjacent the first hole or the second hole in the pattern of holes;
- and
- wherein a spacing distance between two holes that are introduced chronologically in direct succession into the substrate is at least two times as great as a smallest spacing distance between two immediately adjacent holes in the pattern of holes.

- and
- using scanner optics for displacing a laser beam from the laser light source in jumps on the substrate, for carrying out the bore hole strategy.
