  • Patent number: 12122547
    Abstract: An induction heat sealing device for providing a transversal sealing of a tube of packaging material, said induction heat sealing device including a main body including 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, provided 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 held inside the tube are pushed away from a sealing band of the tube as the sealing band is pressed toward the first and second top section.
