Sealing device for the sealing of thermoplastic material.

摘要

The invention relates to a method for regulating the supply of energy to a sealing device for the sealing of thermoplastic material, the electric energy being supplied to the sealing device pressed against the combined thermoplastic material with whose help the said electric energy is converted to thermal energy and that the amount of energy supplied to the sealing device is compensated for heat losses brought about by heat leakage during the sealing operation.
