Abstract
A method for regulating the supply of energy to a sealing device for the sealing of thermoplastic material includes supplying electric energy to a sealing device pressed against the combined thermoplastic material with whose help the said electric energy is converted to thermal energy. The amount of energy supplied to the sealing device is variable to compensate for heat losses brought about by heat leakage during the sealing opertion. An arrangement for carrying out the method is also disclosed.
