The method is aimed at indirectly determining the energy absorbed by a conducting layer ( ) forming part of a strip of packaging material ( ) to be sealed transversely. The method is based on measuring parameters correlated with the power supplied by a current source ( ) to the packaging material ( ) during sealing, and with the temperature of the conducting layer ( ). The temperature measurement takes into account the temperature of the product to be packed, the characteristics of the packaging material, and the characteristics of the mechanical sealing members; correct cutting of the packaging material after sealing is also determined; and the parameters are monitored by measuring associated quantities and by comparison with permissible values.

A regulator cone of substantially cylindrical form is disclosed with four generally V-shaped grooves on its outer circumferential surface. Two of the grooves define primary grooves that extend along the entire active length of the regulator cone. The other two grooves define secondary grooves that extend along the portion of the active length of the regulator cone where the primary grooves have their largest cross-sectional area.
