  • the construction shown in FIG. 3B, in conjunction with the pressure stamp 17, carries out the compression and the dome-like rounding of the sleeve tip in the processing station III. This can result in the cardboard material flowing into the very small gap between these edges in the area of the inner edge 36 of the bell 29 and the outer edge of the anvil 31, in particular when the tool is worn, which causes burr formation in the area of the sleeve tip.
  • the cardboard material has already been compressed in the pre-compression and pre-compression device 2 of the processing station II, it can no longer flow as much into the gap between the edge 36 and the peripheral edge of the anvil 31 in the compression and rounding device 3, as a result of which the formation of burrs and tool wear are minimized.

  • stations VII and IX in which hot glue is injected from above with a hot glue nozzle into the inside of the sleeve in the area of the sleeve tip, the sleeve is fixed from below by a counterholder and flanged inwards by a tool coming from above. This is done in two steps: At station VIII, the sleeve edge is folded tightly inwards. At station IX, this flanged edge is further rolled up spirally.
  • FIG. 5 shows a cardboard sleeve 12 produced according to the invention in a longitudinal section at the top and in a plan view from below the sleeve tip 13.

  • the pre-flanging and post-flanging device 8 and 9 ensure that the flanging edge has the largest possible radius. This is important for a solid and tight assembly of the cardboard sleeve 12 serving as a container for phyrotechnical effect material on the propellant tube 16 of the firework rocket.
  • a cardboard sleeve which is sealed on one side and which is particularly suitable for preferred use as a top sleeve on fireworks rockets can be produced in a rational and space-saving manner.
