Definitions
- the invention relates to a method for producing a firework rocket and a firework rocket.
- EP 0653 983 B1 discloses a method for producing cardboard sleeves which are closed on one side and are essentially cylindrical. This known method comprises the following steps: a) production of cylindrical sleeves with a predetermined diameter and predetermined length, b) conical compression of the sleeve wall at one end of the sleeve, and c) compression of the pressed sleeve end and dome-like rounding of the compressed sleeve tip, so that the latter forms a dimensionally stable dome.
- Step b has a further step b1, through which the cardboard material is pre-compacted during the conical compression of the sleeve wall.
- a further step d results in a smoothing of the inner and outer wall in the area of the compressed sleeve end.
- the cardboard material is pressed and compacted between an axially movable pressure ram inside the sleeve and an outer bell that acts against the compressive force of the ram, with the pressure ram and bell having a shape corresponding to the intended pressing or compression Have outer and inner contours corresponding to compression.
- the travel of the plunger is adjustable, and the bell is spring-mounted axially, with the spring travel determining the pressing pressure.
- the dome-like rounding is carried out by an anvil which is arranged immovably inside the bell and against whose concave anvil surface a convex outer surface of the stamp presses the compacted end of the sleeve.
- a printing step e prints ink on the outside of the flattened case tip.
- glue is introduced into the inside of the case in the area of the tip of the case.
- a flanging step g the edge on the open sleeve side is bent inwards.
- the flanging step g comprises a pre-flanging step g1 and a post-flanging step g2, with the edge simply being bent inwards in the pre-flanging step g1 and being further bent inwards in a spiral manner in the post-flanging step g2.
- Manufacturing steps a to e are carried out with the sleeve standing upright on the die, i.e.
- a fireworks rocket that includes a propellant charge tube and a sleeve produced by this known method, which is closed on one side by a dimensionally stable dome and has a flanged edge on the other, open side.
- the sleeve serves as a container for pyrotechnic effect material and is firmly and tightly mounted with its flanged edge on the propellant charge tube.
- This known fireworks rocket is manufactured by first producing such a sleeve by this known method, then filling an effect set comprising pyrotechnic effect material into the sleeve through the opening surrounding the flanged edge, and finally filling the sleeve in this way is plugged with its flanged edge onto the propellant charge tube in a sealing manner.
- a disadvantage of this known method for producing a fireworks rocket is that the inside diameter of the opening at the open end of the sleeve is reduced by the beaded edge that is crimped inwards, and consequently filling in the effect set is made more difficult.
