  • Patent number: 11933590
    Abstract: A method for manufacturing a housing enclosing a pyrotechnic charge and an installation for implementing this method includes inserting a pyrotechnic charge into a charging volume laterally delimited by a rigid cylindrical charging wall and into a lower part by a first element of the housing to be obtained; positioning a second element of the housing to be obtained of cylindrical shape above the inserted pyrotechnic charge and in the extension of the cylindrical charging wall. The second element has a lateral cylindrical wall of the same shape and diameter as the cylindrical charging wall and is able to cooperate with the first element, and jointly translating the second element and the cylindrical charging wall relative to the first element such as to make the second element cooperate with the first element and form the housing enclosing the pyrotechnic charge.
