Definitions

  • the present invention relates to a method of producing a female embossing tool.
  • the invention relates to a female embossing tool.
  • the invention relates to a pair of embossing tools, comprising a male embossing tool and a female embossing tool.
  • the invention also relates to an embossing module for flat elements for forming packages, equipped with a female embossing tool.
  • a flat element processing machine for example a printing, cutting or folding-gluing machine, is used in the packaging industry, for example to print, cut or fold and glue flat elements, such as cardboard sheets. These printed sheets are then used to make cardboard boxes.
  • machines of the platen press type perform cutting and embossing
  • machines called folder-gluers perform the folding and gluing of blanks or blanks of cartons, to form a package.
  • the embossing step makes it possible to give relief to the sheet of cardboard, for functional reasons and in particular to form pre-folding lines, or for purely aesthetic reasons.
  • the present invention relates to an embossing module provided with a pair of male and female embossing tools, including such a female embossing tool.
  • the invention relates to a method of embossing a carton blank using such a pair of embossing tools.
  • the document EP 0879197 presents an example of platen cutting and embossing machine.
  • the cutting and embossing tools are inserted into the machine and used to cut cardboard sheets.
  • the document WO 2014/135265 presents a machine with rotary embossing tools.
  • the embossing arrangement placed in an embossing cassette is equipped with an upper rotary embossing tool, positioned parallel to a lower rotary embossing tool.
  • a continuous strip of cardboard is embossed thanks to this cassette.
  • the document EP 1932657 discloses a device for embossing braille characters on cardboard blanks with rotary embossing tools.
  • the result of the embossing is a functional relief used for Braille messages on some packaging boxes, especially on the drug boxes and allow tactile reading of the messages.
  • the male and female embossing tools are manufactured, in particular by machining, with protuberances on the surface of the male tool and complementary recesses on the surface of the female tool. Consequently, if the manufacturer wishes to make small series, the cost of manufacturing each pair of tools does not allow to do it with a low cost for each package. Thus, for the manufacture of packaging for consumer goods, these embossing tools being made to measure, they are only affordable for large series, for example of the order of 50,000 to 200,000 boxes. minimum. Small series, in particular of the order or less than a thousand boxes are only possible for high value products, or in the field of luxury. In addition, the order of the tools must be passed well in advance, because of the time necessary to their realization.
  • the manufacturer seeks to obtain the best complementarity of shape between the protuberances on the surface of the male tool and the depressions on the surface of the female tool, and this in order to obtain a deformation of the material ideally without pinching, and without crushing too much reduction in the thickness of the carton, or at least with a minimum of these phenomena.
  • An object of the present invention is to provide a method of making a female embossing tool free from the limitations of known female embossing tools. Another object of the invention is to make the manufacture of packaging more flexible with different embossing arrangements, in order to be able to manufacture small or medium series of packaging. Another object of the invention is to provide a means for obtaining a female embossing tool adaptable to multiple male embossing tools to avoid making new complete tooling for each desired relief modification to the surface of the carton.
  • This method of implementation applies in particular during the first use of the female embossing tool or a female embossing tool already previously returned to an initial form of departure, with its peripheral face devoid of or hollow.
  • the embossing is defined, by way of non-exhaustive example, as any mechanical deformation operation of the flat element by crushing between a positive shape provided with one or more convexities or protuberances, ie the male tool, and a negative form, provided with one or more concavities or recesses, ie the female tool.
  • the embossing can thus be a conventional embossing, grooving, creasing, or others.
  • the material having shape memory properties is defined, by way of non-exhaustive example, as being a deformable material capable of passing from an initial form to a final form.
  • the material having shape memory properties also has the ability to recover its original starting shape if it is subjected to specific conditions depending on the type of material.
  • a flat element is defined, by way of non-exhaustive example, as a sheet, plate, continuous web material such as paper, cardboard, corrugated cardboard, laminated corrugated cardboard, flexible plastic, for example polyethylene (PE), polyethylene terephthalate (PET), bioriented polypropylene (BOPP), or other polymers, or other materials.
  • the flat support is defined, by way of non-exhaustive example, as being a sheet intended to form a cut, and then a packaging box after folding-gluing.
  • this process makes it possible to very quickly produce female tools, without increasing as significantly as today the cost price of each package compared to large series of the order of several hundred thousand dollars. packaging, for example.
  • This method of implementation applies in particular during the second use or a subsequent use of an embossing tool initially having a shape corresponding to a previous use, that is to say with a peripheral face provided with hollow.
  • the material is selected from shape memory metal alloys, and polymeric materials having shape memory properties.
  • the step of wearing the outer face of the female embossing tool in selected conditions, ie the transformation can be done by heating, UV irradiation, or others.
  • embossing embossing à la carte is performed on the flat element with the same female embossing tool, being able to vary in particular the arrangement, the shape, the length, the width, the depth of the lines or any other geometric shape of grooving or embossing.
  • the packaging manufacturer potentially has an unlimited series of possible hollows and therefore possible reliefs for the flat element.
  • the method of producing the female embossing tool is so simple and quick to implement that the overall cost of the pair of embossing tools is reduced by almost half and essentially covers only that of the embossing tool.
  • Male embossing tool both the same female embossing tool has become adaptable to many configurations.
  • the present invention also relates to a planar female embossing tool forming a tool for a platen press for embossing flat elements for forming packages, which comprises a plate with an outer layer made of a shape memory material.
