The present invention refers to an assembly of a support plate (22) and an exit window foil (20) for use in an electron beam device, said support plate (22) being designed to reduce wrinkles in said foil (20), which wrinkles may arise due to surplus foil arising in the assembly process. The foil (20) is being bonded to the support plate (22) along a closed bonding line (26) bounding a substantially circular area in which the support plate (22) is provided with apertures and foil support portions and in which area the foil is adapted to serve as a portion of a wall of a vacuum tight housing of the electron beam device. The invention also refers to a method for using the assembly in a filling machine, as well as a method of reducing wrinkles. La présente invention concerne un ensemble composé d'une plaque de support (22) et d'une feuille métallique de fenêtre de sortie (20) que l'on utilise dans des dispositifs à faisceaux d'électrons. Ladite plaque de support (22) est conçue pour réduire les rides dans ladite feuille métallique (20), lesdites rides pouvant survenir du fait d'un excès de feuille métallique lors du processus d'assemblage. La feuille métallique (20) est collée à la plaque de support (22) le long d'une ligne de collage fermée (26) délimitant une zone essentiellement circulaire dans laquelle la plaque de support (22) comporte des ouvertures et des parties de support de feuille métallique, zone dans laquelle la feuille métallique joue le rôle d'une partie d'une paroi d'un logement étanche sous vide d'un dispositif à faisceau d'électrons. L'invention concerne également un procédé d'utilisation de cet ensemble dans une machine de remplissage, ainsi qu'un procédé de diminution des rides.
