ABSTRACT:
An arrangement for sterilizing a travelling material web comprises a chamber having an inlet and an outlet so that the material web can enter and exit the chamber. Constriction zones are arranged between the inlet and outlet and are connected to one another by an intermediate chamber portion. The constriction zones are designed so that the web material is just able to pass freely between the constriction zones. The intermediate chamber portion is connected to a gas source while each of the constriction zones are connected to a vacuum source.
