Definitions

  • the invention relates to a method for three-dimensional forming of sheet material, in particular natural fibers, such. Paper or cardboard, with a deep-drawing piston and a die, through which or into which the material is drawn.
  • thermoformable material so mainly plastic films, can be umgefomt.
  • Papers and cartons are usually deep-pressed, with a significant wrinkling.
  • the object of the invention is to propose a method which avoids the above disadvantages in the forming of paper and cardboard and provides a deep drawing process for these materials.
  • This object is achieved in that the diameter of the deep-drawing piston plus the material thickness of the deep-drawing material at least approximately corresponds to the diameter of the die.
  • Another very advantageous embodiment of the invention is when the die is formed as a plate, which may have a thickness less than or equal to the forming depth.
  • the initially pot-shaped, provided with a cylindrical, oval or angular side wall molding is formed by means of a mold.
  • the desired shape can be generated very easily and also different wall inclinations, conicities are generated.
  • Other forms are conceivable.
  • Shapes are conceivable which have different angles of the side walls over their horizontal extent. Thereby any shapes are conceivable.
  • the forming takes place in such a way that at least one, preferably two conical sections are produced.
  • a flattened cone to the edge can be created.
  • the molding can be closed very well and safely and the contents are protected.
  • the edge can be brought again into an intended contour.
  • breaking over it is also possible to compensate for occurring stresses of the lid and thus to avoid an undesirable drum effect.
  • An inventively very advantageous apparatus for performing the method described above is provided when a die and a deep-drawn piston are provided, wherein the die may have a thickness which is less than or equal to the deep drawing height.
  • a mold for receiving the molding and a forming die which has a conical shape with at least one slope.
  • the vertically aligned walls of the preform can be widened targeted.
  • the forming die has such a slope that the edge of the molding can slide along this, wherein the slope can assume an angle to the horizontal of about 20 °.
  • the free end of the preform does not need to be specifically treated again. Rather, it is enough to expand, to work with this forming die. A length and circumference compensation takes place by sliding along.
  • an edge surrounding the sealing mold acts as a cutting device for trimming the blank and the lid and so the sealing and trimming can take place in one work step.
  • An additional cutting device is conceivable. Instead of a spring, a mechanical control or positive control can be provided.
  • the seal shape and the seal stamp have a contour which is capable of further deforming, pressing and / or breaking at least one edge of the molding.
  • the pressure or sealing force is limited by corresponding spring arrangements, regulations or the like.
  • Another very advantageous development of the invention is also present when a humidification and / or a heater for the material is provided.
  • the results of the forming can be significantly improved again, especially as used paper, cardboard and cardboard is better deformable and deformable.
  • Fig. 1 denotes a paper material blank which is formed by means of a forming die 2 and a die 3 three-dimensionally.
  • the diameter of the forming die 2 plus twice the material thickness corresponds at least approximately to the diameter of the die 3.
  • the die 3 is formed as a recess in a material plate, preferably a steel plate.
  • the paper material blank 1 is pressed with the forming die 2 through the die. Thereby, a cup-shaped Umformling 34 with a bottom 35 and cylindrical walls 36 is formed.
  • the forming die 2 can either be pressed so deep into the die 3, that even an edge remains, so the Umformling 34 is not completely pushed through the die 3, or the forming die 2 is pressed so deep into the die 3, that just no more edge stops, and the Umformling 34 is pushed at least as far into the die 3 or through this, that it just ends in the Mattritze 3, or falls through it.
  • the die 3 can be made relatively thin, that is, the thickness of the die 3 can be significantly thinner as the height of the Umformlings 34. Important is during the forming process, the deflection of the horizontally lying, flat paper blank in the three-dimensional, pot-shaped shape into it.
  • a hold-down which holds the flat lying material against the die 3 and allows a targeted, defined and controlled slipping of the flat material can be provided.
  • the forming 34 is placed in a conical shape 4.
  • a correspondingly shaped punch 5 moves from above into the forming part and expands it.
  • the Umformling is brought into a conical shape and pressed between the mold 4 and the punch 5.
  • Both punches 5 and 4 can have - as shown in the embodiment - two or more conical sections. A combination of conical and cylindrical sections is conceivable.
  • the thus formed forming 40 is filled and then closed with a lid 41.
  • the lid 41 is flat and is sealed to the Umformling.
  • Other covers and other connection methods are conceivable.
  • the forming member 40 is placed in a corresponding mold 6 and broken with a punch 7 from above. At the same time, the lid 41 already laid on is connected to the forming 40.
  • the mold 6 is movably mounted in a holder 8 so that upon depression, i. Breaking the edge at the same time the edge and the lid 41 can be trimmed.
  • edge between form 6 and holder 8 can be used.
  • a separate separator is conceivable.
  • the mold 6 can be loaded in the holder 8 by means of a spring. Likewise, a mechanical or hydraulic control is conceivable.
  • a three-dimensional cup or a three-dimensional capsule is thus formed in a simple manner from a flat paper or cardboard material.
  • Such capsules can be used, for example, for the preparation of hot or cold drinks such as known coffee capsules made of plastic.
  • these capsules may be equipped with a barrier layer or else be packaged individually or multiply.
