In a flame arrester arrangement which is formed from two metal strips ( 8, 9 ) which are wound together to form a disk having an approximately circular outer circumference and of which a first metal strip ( 8 ) is a smooth strip and the second metal strip ( 9 ) is a fluted strip having defined fluting, the two strips ( 8, 9 ), by bearing against one another, forming defined gaps ( 11 ) for passage of a fluid and being held in position relative to one another by fixing pins inserted into radial bores ( 6 ), the radial bores ( 6 ) can be incorporated without deforming the gaps ( 11 ) even in the region of the bores ( 6 ) by virtue of the fact that the bores ( 6 ) are incorporated by spark erosion without deforming the fluting formed in the second metal strip, such that the gaps ( 11 ) are also present in the region of the bores ( 6 ) in the manner defined by the fluting.
