    摘要: There is described a heating induction sealing device (30) for forming a seal (14) in a packaging material (15,11) comprising an electrically conductive element and advancing, in use, along a first direction (A); the sealing device (30) comprises at least one inductive element (31); inductive element (31) comprises a first and second leg (200;201) within which alternate currents flow, in use, in opposite direction; first leg (200) is configured to induce, in use, a first portion (300) of an eddy current within an area (202) to be sealed of packaging material (15,11); second leg (2O1) faces first leg (200) along a second direction (C); second leg (201) is configured to induce, in use, a second portion (301) of eddy current within area (202) to be sealed of packaging material (15,11); first and second leg (200;201) have a length in a third direction (B) parallel, in use, to first direction (A) and transversal to second direction (C); first and second leg (200;201) are nonsymmetrical with respect to third direction (B), so that seal (14) is formed as continuous along second direction (C).
