Definitions

• the invention relates to an incandescent body consisting of a fabric tube with at least one open end, wherein a fireproof fastening material is provided for fastening the hose ends to a burner or to a molded part for a burner of an incandescent lamp.
• the invention relates to a burner of an incandescent lamp with a rotationally symmetrical surface for fastening at least one end of a filament.
• Such incandescent bodies consist of a circular knitted carrier material, generally viscose is used, which is mixed with metal salts.
• the incandescent body is usually fastened with a twine either directly on a burner or first on a prefabricated molded part for the burner (the molded part is fastened with the
• Incandescent body placed on the burner by the end user) and then burned and lit in the gas flame.
• the carrier material burns off completely and only the oxide skeleton of the metal salts remains.
• Another way is to select the twine with which the incandescent body is bound to the burner.
• a thread is sewn into the fabric.
• Different burners require different binding of the twine.
• a yarn is drawn into the fastening opening or into the two fastening openings of the incandescent body with more or less stitches during production, after which the end user then pulls the incandescent body either onto a ceramic ring or onto an elongated one-part or two-part burner and pulls the yarn ends tightly together and ties them with a knot.
• the incandescent body is drawn together and pre-knotted during the production process, the diameter of the opening remaining in this way being specified to the nearest tenth of a millimeter.
• the fixing material has an influence on the durability of the filament.
• the twine is the most common method of fastening the filament.
• the selection of the twine is subject to various criteria. It must be resistant to high temperatures, should retain textile properties even at high temperatures and should neither become hard nor brittle, and the knot must hold tight.
• the use of a metal clip instead of a twine has also been proposed.
• US Pat. 5116220 describes a round metal clip which is adapted to the shape of the burner but is to be operated manually by the consumer and which connects the incandescent body to the Burner holds tight and is carried through the fabric similar to the twine during production.
• the user-friendliness of this metal clip is at the expense of the durability of the incandescent body on the burner, which is lower than the incandescent bodies attached by means of twine.
• the metal clip described above was improved in US Pat. # 5639231 and describes a similar metal clip. Modified shape so that the oxide structure is no longer pressed onto the burner by the metal clip.
• the advantage over the above Metal clip lies in the improved durability of the filament on the burner and the durability achieved is comparable to the durability of a filament fastened with twine.
• the object of the invention is to provide an incandescent body or a burner for incandescent bodies, which independently of the o.a. Fastening materials has an increased durability of the filament when exposed to bumps and impacts.
• a glow body consisting of a fabric tube with at least one open end, a fireproof fastening material for attaching the hose ends to a burner or to a molded part for a burner of an incandescent lamp is provided in that at least one open end of the incandescent body and at least on the side facing the burner or the molded part for the burner at least one further, preferably connected to the incandescent, fireproof material is provided between the burner and the incandescent body and as a result the incandescent body has increased mechanical durability on the burner.

• the incandescent body in the sense of the invention wears out in a completely different way than the conventional incandescent body.
• the conventional incandescent body is destroyed by successively separating the oxide structure from the twine until it is no longer held by it and falls off the burner. If the incandescent body produced in the sense of the invention is exposed to shocks, impacts and vibrations, the oxide structure no longer separates from the binding yarn and is therefore held on the burner for a considerably longer time.
• This incandescent body is destroyed underneath the attachment, specifically in the incandescent body itself, so that the durability of this incandescent body depends only on the nature of the oxide structure from which the incandescent body is made and on the shape of the burner.
• the further refractory material connected to the incandescent body thus serves, when the incandescent body is subjected to shocks, impacts and vibrations, as a protective medium which prevents the oxide structure from separating from the fastening material which serves as a binding medium.

After the sewing thread has been sewn around the incandescent body according to the usual method, it can also be worked in again around or along the opening of the incandescent body and thus becomes the protective medium in the second circulation.
