Abstract
The present invention provides a low mass, flexible heat transfer member which is made of a suitable material to transfer heat, as well as a plurality of independent heat generating members to provide zoned heat along a portion of the length of said heat transfer member. The heat generating members are encased in an electrical insulation material which is secured to the heat transfer member. The consolidated structure, i.e. the heat transfer member and heat generating members constitute a flexible strip. The ends of said flexible strip are actually sections of the heat transfer member and these ends are respectively looped around two pins, or studs, and over the respective loops there is positioned an associated slotted hollow tube. The slotted hollow tube is formed to be located in a base of a machine with which the flexible heating means is used. When the hollow tubes are located in the base, the consolidated structure, made up of said heat transfer members and heat generating members, can be spring loaded to be held in tension which enables the flexible strip to follow an item which is being heated.
