<p>A device for heating an article, especially a heat recoverable article, by means of a gas heating tool 7 comprises an element 1 which is preferably hollow and is heated by a flame from the tool, means 11, 12 for positioning the article within the element and a support 2 for retaining the element on the heating tool. In use, a flame from the tool is directed on to the element and the article is heated over a major part of its surface by radiant heat emitted by the element while being shielded from the flame by the element. Preferably the element is shaped so that the flame is guided around a major part of the article thereby increasing the uniformity of heating of the element. The device is particularly suitable for applying heat recoverable end caps on to mineral insulated cables. <IMAGE></p> |
