A magnetizing device in a web processing machine for magnetizing a magnetisable area of a web of packaging material is disclosed. The magnetizing device comprises a first magnetic component having a north pole and a south pole, and a second magnetic component having a north pole and a south pole. Poles of a first and same polarity are arranged adjacent in an opposed relationship and poles of a second and the same polarity are arranged remote from each other.

Method and device for magnetising a package material, and packaging material magnetised with said method

A packaging material comprises a plurality of magnetizable portions thereon, the magnetizable portions comprising at least one spot per package to be formed from the packaging laminate. The packaging material further comprises at least one preparation feature for enhancing finishing of packages, wherein the at least one preparation feature is aligned with a magnetic field mark in the at least one magnetizable portion.

Packaging material comprising magnetisable portions

A packaging material comprising a plurality of magnetisable portions thereon comprising at least one spot per package to be formed from the packaging material is disclosed. At least one of the magnetisable portions provides a first magnetic mark carrying a magnetic field pattern providing position information related to finishing of respective package to be formed.

A packaging material comprises a plurality of magnetizable portions thereon. The magnetizable portions are provided as at least one spot per package to be formed from the packaging material. The spots comprises magnetizable particles.

A packaging material comprises a plurality of magnetisable portions thereon. The magnetisable portions are provided as at least one spot per package to be formed from the packaging material. The spots comprise magnetisable particles and are provided on the side of the paper layer intended to face to the interior of the package.

A packaging material comprising a plurality of magnetisable portions thereon comprising at least one spot per package to be formed from the packaging material is disclosed. At least one of the magnetisable portions, per package, provides a first magnetic mark carrying a magnetic field pattern, and another of the magnetisable portions, per package, provides a second magnetic mark carrying a magnetic field pattern.

A packaging material comprises a plurality of magnetisable portions thereon, the magnetisable portions comprising at least one spot per package to be formed from the packaging laminate. The packaging material further comprises at least one preparation feature for enhancing finishing of packages, wherein the at least one preparation feature is aligned with a magnetic field mark in the at least one magnetisable portion. Methods for writing and reading, respectively, a magnetic mark on a packaging material are also disclosed.

A system and a method for production of a packaging laminate that comprises a layer containing magnetizable particles. The method involves marking faults, such as single spot defects and splices, on the packaging laminate by the application of a magnetic field to make a magnetic mark on the packaging laminate. A packaging device is arranged to sense the presence of the magnetic mark related to a package made from the packaging laminate.

System and method for producing a packaging laminate and packages made from the packaging laminate

A device for fastening an emitter to a housing comprises a manoeuvre element slidable in a first direction, an activating element slidable in a second, fastening direction that is inclined in relation to the first direction, with the first and second elements are interconnected via at least one cam mechanism. In addition, a fastening element is slidable in the second direction, wherein the activating and fastening elements are interconnected via at least one elastic element. The fastening element is adapted to move, in response to displacement of the manoeuvre element in the first direction, between a fastening position in which it produces a fastening force onto the emitter and an open position in which the fastening force is released.

Device for and method of fastening an emitter

The invention refers to a method and device for ventilating a device for electron beam irradiation of a web (W), the method comprising the steps of: providing a first chamber () comprising a web inlet opening () and a web outlet opening () and a web outlet opening (), providing a second chamber () extending inside the first chamber (), the second chamber () comprising a a web inlet opening (), a web outlet opening (), and an electron exit surface () through which electrons are adapted to be emitted into the second chamber (), passing the web (W) through the second chamber (), and creating a flow of a gaseous fluid through both the first and second chambers () in a direction opposite the direction of travel of the web (W) by supplying said fluid into the web outlet opening () of the first chamber () and providing at least one outlet ().

Method and device for electron beam irradiation

The present invention concerns a device for fastening an emitter to a housing comprising a first, manoeuvre element () being slidable in a first direction (, B), a second, activating element () being slidable in a second, fastening direction () being inclined in relation to said first direction (, B), whereby the first and second elements () are interconnected via at least one cam mechanism (). Moreover, the device further comprises a third, fastening element () being slidable in the second direction (), whereby the second and third elements () are interconnected via at least one fourth, elastic element (), whereby the third element () is adapted to move, in response to displacement of the first element () in said first direction (, B), between a fastening position in which it produces a fastening force onto said emitter () and an open position in which the fastening force is released.

The present invention refers to a device for electron beam irradiation of at least a first side of a web, the device comprising a tunnel through which the web is adapted to pass, said tunnel being provided with a web inlet portion, a web outlet portion and a central portion adapted to receive at least a first electron beam emitter provided with an electron exit window through which electrons are adapted to be emitted into the tunnel. The tunnel is being angled at least two locations in each of the inlet portion and the outlet portion in such a way that any X-ray formed during the electron beam irradiation of the web is forced to hit the tunnel wall at least twice before exiting the tunnel.
