METHOD AND UNIT FOR WRAPPING AN ARTICLE IN A SHEET OF THERMOPLASTIC WRAPPING MATERIAL |
摘要 |
In a method for wrapping an article in a sheet of thermoplastic wrapping material, the temperature of an at least partly metal belt (5) looped and induction heated to seal wrapping material (4) is detected by detecting a first signal (S1) related to the voltage (V) applied to the belt (5), and a second signal (S2) related to the current (I) circulating along the belt (5); and by calculating the electric resistance (R) of the belt (5) being related to the temperature (T) of the belt (5).
