Abstract
A catalytic heating means is disposed in a heating chamber of a tubular body member defining a hair winding portion. The curling device includes a supply of a liquid fuel and aspirating means for vaporizing the fuel and mixing the vaporized fuel with air to supply a vaporized fuel/air mixture to the catalytic heating means. A self-contained ignition means proximate the catalytic heating means is provided for initiating the oxidation of the vaporized fuel/air mixture in the presence of the catalyst. The catalytic heating means includes a woven sleeve with an unravelled end to act as a flame arrestor and increase ignition efficiency.
