Induction sealing device for heat sealing packaging material for producing sealed packages of pourable food products |
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 along a direction (A); sealing device (30) comprises one first inductive element (31) and one second inductive element (32); first inductive element (31) comprises a first portion (35) facing second inductive element (32) and defining with second inductive element (32) a passage (28) for packaging material (15,11); and a second portion (36); sealing device (30) is selectively arrangeable in a first configuration, in which alternate currents flow within first and second inductive element (31,32); first portion (35) and second inductive element (32) are configured to generate a first magnetic flux (M1) transversally to direction (A), when sealing device (30) is arranged in first configuration; second portion (36) is configured to generate, in use, a second magnetic flux (M2) with a main component parallel to direction (A), when sealing device (30) is arranged in first configuration. |
