Abstract
The invention relates to the connection of tubular sections ( ) of combustible propellant charge cases consisting of one or several windings of textile threads which are connected to propellants by binding means. Said charge cases are dimensionally stable and have a high level of mechanical resistance. The aim of the invention is to create a safe, resistant, tight connection and to ensure that cracks do not form unchecked during the connection process. To this end, the tubular sections ( ) to be connected are inserted into each other, said inserted tubular sections ( ) are connected by means of a non-releasable snap connection, and at least one longitudinal cut ( ) is made in an axial direction, extending in the area of the connection.
