Abstract:
    A resistor element assembly for a glass sheet heating furnace and a method of replacing a resistor element. A resistor element is built by placing successively in longitudinal direction ceramic elements, with a resistance wire wound therearound. Between the ceramic elements are fitted ceramic spacer blocks. A compaction spring can compresse the resistor element at all operating temperatures. The resistor element can be replaced by releasing said spring from the support frame and by pulling the resistor element out of a furnace by utilizing a core pin extending through the entire resistor element.
