Abstract:
A flame trap filter including a grid structure, wherein the grid structure determines grid openings which are bordered by intersecting strip sections, and/or wherein the grid structure is formed by a laid scrim. A method for producing a grid structure of a flame trap filter includes the step of allowing a substance to solidify on a substrate, in order to form at least one strip section of the grid structure. Alternatively or in addition, the method includes the step of compressing a material for the flame trap filter or a semi-finished product of the flame trap filter at points, e.g. by mechanically deforming the material or the semi-finished product, in order to form at least one strip section of the grid structure.
