Abstract
Abstract A delay charge is filled into a tubular delay charge carrier closed on one end, and the filling height is measured subsequently. Only when the sufficient filling height of the delay charge has been reached, the bottom part of said tubular delay charge carrier is provided with an aperture so that only then the detonating charge of the hand grenade fuze can be ignited.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
87 words
A method for producing a tubular delay charge carrier for a hand grenade fuze, said carrier being open on both sides, a detonating charge being only ignited if a delay charge is contained in said carrier, wherein a tubular delay charge carrier closed on one side by a bottom part is made, said delay charge is filled into said carrier and the filling height is measured subsequently, whereupon said bottom part of said carrier is perforated only if the filling height of said delay charge is sufficient.
Claim 2
Independent Claim
87 words
A method for producing a tubular delay charge carrier for a hand grenade fuze, said carrier being open on both sides, a detonating charge being only ignited if a delay charge is contained in said carrier, wherein a tubular delay charge carrier closed on one side by a bottom part is made, said delay charge is filled into said carrier and the filling height is measured subsequently, whereupon said bottom part of said carrier is perforated only if the filling height of said delay charge is sufficient.
Claim 3
Dependent Claim
81 words
A method according to claim 1, wherein, after filling said delay charge into said carrier, a control piston is inserted until reaching the desired filling height and a punch is arranged at said bottom part of said carrier, whereupon the distance between said control piston and said punch is reduced, depending on the actual filling height said tubular delay charge carrier thereby either being pushed onto said punch, thereby perforating said bottom part, or being further pushed onto said control piston.
