HEAT-SEALING METHOD AND DEVICE FOR IMPLEMENTING SAME

摘要

The invention relates to a device which is used for the heat-sealing of a thermoplastic synthetic film to a thermoplastic synthetic container. The inventive device comprises at least one thermal electrode (11) which is made from a material with high thermal conductivity. The aforementioned electrode is equipped with a metal section (30) having electrical connection terminals (31) at the ends thereof. A heat flux sensor (32) comprising two electrical connections (33) is also provided, and the lower face thereof is fixed mechanically to the upper part of the above-mentioned section (30). In addition, the upper face of said heat flux sensor (32) is fixed to the lower face of a thermal capacitor (34) which is made from a material with high thermal diffusivity and conductivity. Furthermore, a thermocouple (35) is mounted in a cavity in the metal section (30).
