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.

Abstract: An induction heat sealing device (300) for providing a transversal sealing of a tube (104) of packaging material, said induction heat sealing device (300) comprising a main body (302) comprising a first and a second sealing surface (314a, 314b) arranged to face the packaging material during a sealing state (S), a recess (308) provided in the main body (308) for receiving a knife during a cutting state (C), wherein the first and second sealing surface (314a, 314b) are placed on opposite sides of the recess (308), and an electric conductor arrangement (306a, 306b, 306c, 306d), provided in the main body (302), for inducing eddy currents in the packaging material during the sealing state (S), wherein at least part of the first and second sealing surface (314a, 314b) are inclined and provided with a first and a second top section (316a, 316b), respectively, such that particles in a product held inside the tube (104) are pushed away from a sealing band of the tube as the sealing band is pressed towards the first an

Abstract: The present disclosure relates to an induction sealing system for heat sealing packaging material for producing sealed packages of pourable food products, said sealing system may include a sealing jaw and a counter-jaw. In some embodiments, the sealing jaw may include at least one inductor device having at least one active surface configured to contact said packaging material; at least one flux-concentrating insert; a supporting body including heat-conducting material, said supporting body housing, said at least one inductor device and said flux-concentrating insert; and an interactive surface configured to press against said packaging material. In some embodiments, the counter-jaw may include at least one pressure pad made of elastomeric material, said at least one pressure pad configured to provide a counter pressure to the sealing jaw, wherein said at least one pressure pad has an arched convex contact area with height in the direction towards the sealing jaw.

Abstract: The present invention relates to a sealing band for a sealing jaw arrangement, comprising a contact surface and an opposite bottom surface, a first portion adjacent to the contact surface and a second portion adjacent to the bottom surface. The portions are separated by a waist, and said sealing band is symmetrical along a first axis that extends perpendicularly from a middle of the bottom surface, and the waist between the first portion and the second portion is located closer to the contact surface than to the bottom surface. The invention also relates to a counter jaw for holding the sealing band, and to a sealing jaw arrangement comprising such a counter jaw and a heating jaw.
