There is described an induction sealing device (15) for heat sealing packaging material for producing sealed packages of pourable food products and fed in a first direction (A). The sealing device (15) has induction means (20, 21) interacting with the packaging material by means of a pair of first active surfaces (26) and a pair of second active surfaces (25) interposed between the first active surfaces (26) in the first direction (A) ; and the second active surfaces (25) have, in the first direction (A), a width (L1) greater than the width (L2) of the first active surfaces (26) at least along most of the length of the first and second active surfaces (26, 25) in a second direction (B) perpendicular to the first direction (A). |
