Abstract
A close quarter electric resistance heater comprises a ribbon heater element that is woven between ribbon support segments and within a heater shell. The ribbon support segments form an annulus on each end of the heater and are linked to each other using connectors. The connectors space the ribbon support segments apart from each other to facilitate the weaving of the ribbon element along the inside of the heater shell for heating purposes. The connectors also link the ribbon support segments to the shell. The ribbon heater element has faces that are wider than its edges and the ribbon heater element is woven on the support segments such that the edges face the heater shell. This configuration minimizes the migration of the ribbon heater element towards the shell and possible short circuiting of the heater.
