The invention relates to a production method for a burner fabric membrane () consisting of special steel fabric layers for burning fuel/air mixtures. Additional passages () in the fabric () are produced by the displacement of the fabric and the mouths of the passages protrude from the membrane surface (). 11. Method for production of a burner woven fabric membrane () ,{'b': 1', '8, 'a) wherein the membrane () preferably consists of metal woven fabric layers () composed of inorganic material such as stainless steel,'}{'b': 8', '1, 'b) with the ability of a premixed and ignitable fuel/air mixture, which is combustible on the surface of the membrane (I), to flow through the woven fabric () of this membrane (), and'}{'b': 2', '3', '1', '4', '8, 'c) with a connection of the two sides (, ) of the membrane (), aside from by way of the woven fabric itself, by way of additional passages () in the woven fabric () for the fuel/air mixture, as an additional pass-through for the premixed fuel/air mixture,'}wherein{'b': 4', '8, 'd) these additional passages () are produced by means of at least partial displacement of membrane woven fabric (),'}{'b': 5', '6', '7', '8', '4, 'e) wherein this displacement takes place by means of mandrels or pins (, , ) that penetrate into the membrane woven fabric () and determine the orifices of the additional passages (), and'}{'b': 9', '11', '12', '3', '3', '1', '2, 'f) wherein after displacement, the orifices (, , ) of the passages project out of the surface (), on the surface () of the membrane () that faces away from the inflow side () of the passages, in the flow direction of the fuel/air mixture, or wherein fibers exit from the walls of the passages, toward their inside.'}2. Production method according to claim 1 ,whereinat least two woven fabric layers or fiber wovens are used in the production of the membrane, and wherein these woven fabric layers or fiber nonwovens are disposed one on top of the other and sintered to one another.3. ...
