The invention refers to a device () and method for sterilizing partly formed packages () in a packaging machine. The device () comprises an inner chamber () and an outer chamber (), the inner chamber () being provided with a sterilization unit (). Further, it comprises a carrier unit (), comprising a separating member () and a package carrying member (), which is being adapted to rotate between a first position in which the package carrying member () is located in the outer chamber (), and in which the separating member () separates the inner chamber () from the outer chamber (), and a second position in which the carrier unit () has rotated a package () into the inner chamber () and in which the separating member () separates the inner chamber () from the outer chamber ().

Device and method for sterilization

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.
