  • ie residues are removed mechanically with the aid of special tools.
  • a package is known to remove, which comprises a carrier layer of paper, cardboard or cardboard.
  • the carrier layer is coated on one side with a decorative layer and has a carrier layer partially severing the predetermined bending line, ie a folding groove.
  • the predetermined bending line divides the packaging into adjacent packaging regions, which in the folded state enclose a predefinable bending angle with one another.
  • an extended in the direction of the predetermined bending line wedge-shaped material recess is provided in the carrier layer, which has a wedge angle which is equal to the bending angle.
  • the material recess is produced by means of two laser beams, ie by means of laser beam energy.
  • the two laser beams are aligned with each other so that they enclose the wedge angle with each other.
  • a piece of material is cut out of the carrier layer by means of the laser beams, to thereby produce the material recess.
  • a disadvantage of this method is that the piece of material must be removed. Thus, at least one additional process step is required, so that the package or its blank is very expensive and therefore time-consuming and costly to produce.
  • a first aspect of the invention relates to a blank for producing a three-dimensional structure, in particular a packaging, a display or the like.
  • the blank comprises at least one layer of paper, cardboard, in particular corrugated cardboard, or plastic.
  • the at least one layer has at least one folding groove, which is produced by means of laser beam energy.

  • Cross-section which has a different shape of a wedge shape. So that, for example, the packaging can be filled with at least one product, in particular by machine, it is necessary that restoring forces act on the blank in its folded or bent state along the at least one folding groove. These restoring forces ensure that the blank and thus the packaging erect at defined locations and can be filled in the sequence.

  • the blank and thus the packaging weakens so that the restoring forces are no longer sufficient or lost, so that the above-described, in particular mechanical and thus fast filling or gluing and / or bonding is no longer possible.
  • a wedge-shaped folding groove is then a so-called dead grooving.
  • a wedge-shaped folding groove is therefore unsuitable in the field of the automatic production of blanks and packages as well as the automatic filling of the packages.
  • a further disadvantage of a wedge-shaped folding groove is that on one of the side on which the folding groove is arranged, the further side of the blank facing away can cause damage, in particular cracks, in the region of the folding groove when the blank is folded along the folding groove. Due to such damage, packaged goods received in the packaging can escape from the packaging. Furthermore, the further side is a visible side of the packaging visually perceptible by a user of the packaging, so that such damage adversely affects the visual impression of the packaging.

This means that the layer is weakened most strongly by the folding groove at the groove bottom, since the groove bottom is adjoined in the depth direction of the folding groove by only a very small residual wall thickness of the layer.
  • the layer or blank is conventionally particularly susceptible to damage in the region of the groove bottom, in particular on the visible side, when the blank is bent. Since now the groove base arcuate, in particular round or elliptical, is formed or has a planar extension, forces and force peaks arising during folding can be kept particularly low. This does not cause damage even if the blank is folded several times along the folding groove. In addition, the restoring forces can be adjusted particularly needs-based by these embodiments of the groove bottom.

  • Such a folding groove allows a defined folding or a defined and advantageous bending of the material of the layer along the folding groove, so that the effect of a creasing arises. As a result, the resulting restoring forces can be adjusted in a targeted manner and damages the blank when folding.
  • a second aspect of the invention relates to a method for producing a blank for a three-dimensional structure, in particular a packaging, a display or the like, in which on at least one side of at least one of paper, cardboard, especially corrugated cardboard, or plastic formed layer of the blank at least one folding groove of the at least one layer is produced by means of laser beam energy.

  • a line 70 is shown along which a topography of the folding groove 14 in an in Fig. 21 shown graph 72 is illustrated.
  • the path along the line 70 in the transverse direction of the folding groove 14 in the unit millimeter is plotted, while on the ordinate 76, the topography in the unit millimeter is plotted.
  • a course 78 illustrates the topography of the folding groove 14.
  • the folding groove 14 by means of the laser beam is particularly accurate to produce, the topography of the folding groove 14 is not or only slightly different from the topography of the adjoining the folding groove 14 areas 30 of the inside 26.
  • Fig. 22 shows another plan view of the folding groove 14 to illustrate their embodiments.
  • Fig. 23 shows by means of the laser or its laser beam, the blank 10, in particular at its outer edges and / or inner contours, are cut so that thereby also an outer contour of the blank 10 by means of Laser beam can be tailored to demand, accurate and fast.
