An inductor for transverse sealing a packaging material tube filled with food product comprises a main body comprising first and second sealing surfaces facing the packaging material during a sealing state, a recess in the main body for receiving a knife during a cutting state, and an electric conductor arrangement, in the main body for inducing eddy currents in the packaging material during the sealing state. The first/second sealing surfaces each comprise a top section, an inner sealing section between the recess and the top section, and an outer sealing section between the top section and an outer edge of the inductor. The inner sealing section is inclined towards the recess, and the outer sealing section is inclined towards the outer edge, so that product in the tube is pushed away from a sealing band of the tube as the first/second sealing surfaces are pressed towards the sealing band.

Inductor for transversal sealing, a packaging machine comprising the inductor for transversal sealing and a method thereof

An induction heat sealing device for providing a transversal sealing of a tube of packaging material, said induction heat sealing device comprising a main body comprising a first and a second sealing surface arranged to face the packaging material during a sealing state, a recess provided in the main body for receiving a knife during a cutting state, wherein the first and second sealing surface are placed on opposite sides of the recess, and an electric conductor arrangement in the main body, for inducing eddy currents in the packaging material during the sealing state, wherein at least part of the first and second sealing surface are inclined and provided with a first and a second top section, respectively, such that particles in a product inside the tube are pushed away from a sealing band of the tube as the sealing band is pressed towards the first and second top section.

Induction heat sealing device and a method for transversally seal a tube of packaging material
