AN INDUCTOR FOR TRANSVERSAL SEALING, A PACKAGING MACHINE COMPRISING THE INDUCTOR FOR TRANSVERSAL SEALING AND A METHOD THEREOF

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.

A method accurately detects biting of a foreign object in a packaging machine. A control apparatus controls a packaging machine that sequentially seals and/or cuts a packaging material transported in a first direction using a rotor. The rotor is arranged to have a tangent to its outer circumference portion in contact with the packaging material extending in the first direction. The rotor is drivable and rotatable by a driver. The control apparatus includes an information obtaining unit that obtains information indicating a rotational position of the rotor and a status value of the driver in predetermined cycles, and a determination unit that determines a presence of an abnormality in a sealed portion of the packaging material using, from the information obtained by the information obtaining unit, a status value of the driver corresponding to a rotational position of the rotor falling within a predetermined range or being a predetermined position.
