Abstract
The present invention relates to an induction sealing device for heat sealing of packaging material. The sealing device comprises a conductor partly encapsulated in a supporting body for cooperation with the packaging material during sealing. The coil conductor has a reduced cross sectional area at at least one position along the coil conductor so as to concentrate the magnetic flux induced by the coil conductor at the at least one position. The invention also relates to a method of heat sealing a packaging material using the induction sealing device.
