The notching device may include an elastic ring for exerting a radial compression force on the shell mouth adjacent the at least one circumferential notch to press a portion of the shell mouth into the at least one circumferential notch, and a device for laterally compressing the elastic ring. The lateral compressing device actuating the elastic ring to exert the radial compression force on the shell mouth.
