The magnetic field concentrator (306, 406a, 406b) is injection molded in said main body (302, 402a, 402b). For this purpose the main body (302, 402a, 402b) is provided with at least one hole (312a, 312b) to gate material for forming said magnetic field concentrator (306, 406a, 406b) into an interior of said main body (302, 402a, 402b).

A method for quality control of a packaging system is provided. The method comprises receiving a record of packaging identification data, wherein the record of packaging identification data being related to a package. Next, identifying and receiving a record of machine data using said record of packaging identification data, wherein said record of machine data being related to a machine set up used when producing said package. Thereafter, identifying a packaging quality parameter to be checked based on said record of machine data, and requesting a record of packaging quality data related to said packaging quality parameter.

An ultrasonic sealing apparatus for paper packages achieves more stable ultrasonic sealing by cooling the horn during ultrasonic sealing which would otherwise be unstable due to heat imparted to a horn by continuous sealing. An end portion of a horn of a casing that includes the horn and a converter, or the horn, a booster and the converter is cooled by supplying air to a frame portion exposed toward an anvil side.

An anvil is provided in an ultrasonic sealing machine, in which vibration applying surfaces of a pair of horns and an abutment surface on an end face of the anvil cooperate with each other to bond a laminate. The abutment surface includes left and right welding surfaces which are disposed in the extending direction of the vibration applying surface and protrude toward the horns to face two vibration applying surfaces. The left and right welding surfaces each have an area per unit length in the extending direction, which continuously or step-wisely increases with an increase in distance from a center of the seal area, which is a region where the two vibration applying surfaces are adjacent to each other.

A work station for a packaging machine comprises a tool structure and a tool movable relative to the tool structure by means of a drive. The drive comprises at least one countermagnet which is operatively connectable to an electromagnet and movable relative to the electromagnet. The drive further comprises a mechanism by means of which the movement of the tool is unidirectionally coupled to the relative movement of the countermagnet relative to the electromagnet.

An apparatus for packing articles, wherein the packing is formed by at least one web material, wherein typically a plurality of individual juxtaposed runs of web material and a number of more or less packed articles are conveyed on the runs, wherein the apparatus includes first mechanism which, during packing of articles, joins the web material continuously in its longitudinal direction, as well as other mechanisms for producing individual joints and for separation of the articles in a transverse direction of the web material, wherein the mentioned other mechanisms are arranged on moving means adapted to move in the same direction and at the same speed as the web material and the articles being packed, called the X-axis, and in a direction towards the web material and the articles arranged thereon, called the Y-axis.

The present invention relates to an induction sealing device for heat sealing packaging material for producing sealed packages. The present invention also relates to a method of manufacturing such an induction sealing device. The device comprises at least one inductor made of an alloy comprising silver and copper.

There is described a sealing device for sealing packages filled with a pourable product within a packaging machine. The sealing device has at least one sonotrode comprising at least a sonotrode head and a vibration control unit connected to the sonotrode head and configured to actuate ultrasonic vibrations of the sonotrode head. The vibration control unit comprises one or more piezoelectric transducer devices configured to generate ultrasonic vibrations to be coupled into the sonotrode head and one or more temperature sensors configured to measure the temperature of the one or more piezoelectric transducer devices for determining and/or monitoring respective operating states of the one or more piezoelectric transducer devices.

A fin sealer and method to seal a radially outwardly directed fin of a tubular web structure by directing the fin through a nip between a first and a second fin sealing rollers while communicating heat to the fin through at least one of the fin sealing rollers is provided. The fin sealer is configured to maintain a nominal face-to-face relation between an outer annulus of the first fin sealing roller and an outer annulus of the second fin sealing roller with a flexible connection between a hub element of the second fin sealing roller with the outer annulus of the second fin sealing roller.
