In a continuous annealer the wire (1) passes over a pulley (3) to which is applied a voltage V and over a pulley (4) earthed via a fixed resistor (6). The resultant current in the wire heats it to the annealing temperature. A second fixed resistor (8) is in series with a variable resistor (7) set to produce a reference voltage. If the voltage drop across the two fixed resistors differs, an error signal is developed by a circuit connected to terminals (9 and 10) and used to change the level of power supplied to the annealer and thus stabilize the temperature of the wire. <IMAGE> |
