ABSTRACT:
The invention relates to a device for sealing of the aperture in a weapon cupola for the barrel of the weapon and which permits elevation movements of the barrel. The device comprises an elongate bellows made of plastic material which is divided into two halves which are in contact with each other along the center line of the barrel aperture. The barrel extends out between and presses the two halves of the bellows apart. Because of the bellows-shaped elastic material, this pressing apart can easily take place, and the bellows resumes its shape and covers the barrel aperture both below and above the barrel. In order to cover the gap which arises just above and below the barrel a protective plate is adapted to the bellows and thus participates in the elevation movements of the barrel.
