Abstract: Mechanically producing a self-extinguishing candle (50) made of powdered material in a molding device, comprises: (a) separating the wick of the candle to be produced in the current cycle; (b) withdrawing the wick tube with wick which is projecting through the wick tube end from a starting position in the mold cavity; (c) folding the protruding section of the wick; (d) withdrawing the wick tube again with the wick; (e) filling the mold cavity with the powdered material; (f) pulling the wick tube from the mold cavity; (g) pressing the candle; and (h) removing the candle from the mold cavity. Mechanically producing a self-extinguishing candle (50) made of powdered material in a molding device comprising a mold cavity (4) loadable by press die for the candle, an axially movable wick tube (9) arranged in the mold cavity for receiving a wick of the candle, a cutting device (13) arranged outside the mold cavity for cutting the wick, a filling device (16) for filling the mold cavity with the powdered material, and a wick feed, comprises: (a) separating the wick of the candle to be produced in the current cycle, which is guided as a continuous wick from the wick storage through the wick tube from the wick prepared in the previous cycle, which is removed from the mold cavity candle by the cutting device; (b) withdrawing the wick tube with wick which is projecting through the wick tube end from a starting position in the mold cavity such that the wick tube end is arranged at an intermediate gap within the mold cavity on the mold cavity end and wick section protrudes on the mold cavity end; (c) folding the protruding section of the wick such that wick section is placed transversely to the longitudinal direction of candle within the mold cavity; (d) withdrawing the wick tube again with the wick such that the folded-over section of the wick is placed in the mold cavity at a safe distance from the mold cavity end; (e) filling the mold cavity with the powdered material, and pre-compacting the powdered material; (f) pulling the wick tube from the mold cavity relative to the wick; (g) pressing the candle while fixing the wick in the candle body with the safety margin of folded-over wick section for forming candle base by the mold cavity; and (h) removing the candle from the mold cavity by feeding the wick for the next candle to be produced in the wick tube, which is repositioned in its initial position of the wick storage, where the above mentioned steps are cyclically repeated. An independent claim is also included for a self-extinguishing candle comprising a candle body having a base and a head, and a wick embedded in the plug body and protruding at the head, whose bottom end is folded in a wick section transversely to the direction of the wick, and a safe distance of the folded-over bottom end of wick section for the base of the candle.
