Definitions

  • the invention relates to an embossing tool for chemical and / or physical connection or embossing of one or more layers of sheet-like materials, with two embossing dies that are at least opposite one another on a contact line, on which embossing points and / or embossing surfaces are arranged, which are at least along the contact line of the embossing dies partially overlap.
  • the invention further relates to a method for producing an embossing mold for such an embossing tool and the use of an embossing mold as a master mold for a counter mold. A method for producing chemically and / or physically bonded or embossed layers of sheet-like materials is also described.
  • a web-like material consisting of several layers is conventionally bonded by placing the layers between two rollers, at least one of which introduces the impressions into the web-shaped material, these impressions generally being provided by positive locking, but also by chemical-physical measures. Connection points are established.
  • the resulting web-like material can then optionally be further processed, for example cut to the known hygiene tissue.
  • embossing In the embossing process, a distinction is made between game embossing, in which an embossing roller runs against a smooth counter-roller, which may have an elastic coating.
  • a die roller and a male roller run against each other and create a connection of the web-shaped materials through the resulting embossing.
  • the fine embossments on one side of the web-shaped material are concave inwards and protrude convexly on the other side. These convex raised areas give the embossed material a rough character and should therefore be avoided.
  • FIG. 7 shows a sectional view through a cellulose cloth which consists of four webs 14, 15, 16 and 17, which are formed between an embossing roller and a counter-roller on embossments 19, 19 'by the wild embossing process get connected.
  • the axes of rotation of the embossing roller and the counter roller are designated by the reference numbers 25 and 26, respectively.
  • the web intake, which is caused by the different flow path of the webs 14, 15, 16 and 17, is shown with the dimension arrow 18 or 18 '.
  • the different web feed results from a longer path of the web from web 17 to web 14.
  • the points 19 and 19 'connected by the embossing lie deeper than the raised surface 20 and higher than the surface 20' of the cellulose cloth.
  • the raised embossing surfaces 21 and 22 or the opposing surfaces 23 and 24 each lie in a plane parallel to the axes 25 and 26 of the rollers.
  • the embossing surfaces of the individual embossing molds lie in a plane parallel to the axis of rotation when working with cylindrical embossing tools, since only for such designs can machining be carried out on commercially available cylindrical grinding machines, in which the cutting tools move past a rotating embossing cylinder. As a result, the optical design of the surface structure of the web-like material is severely restricted.
  • an embossing tool that the embossing surfaces are at least partially at different distances and / or at certain angles to a reference line or a reference surface of the embossing molds are arranged progressively.
  • the individual embossing surfaces are therefore not necessarily in a surface symmetrical to the embossing mold axis, since there is no need for machining on commercially available cylindrical grinding machines.
  • Embossing surfaces that are not in one plane at an equidistant distance from the embossing mold axis have different circumferential speeds with the same angular velocity of the embossing surfaces, which can offer advantages if the different friction between the embossing surface and the material to be embossed and the opposing embossing surface is to be used. This result corresponds approximately to that of cold welding.
  • the size, shape, position and distance of the embossing points or embossing surfaces is selected so that the load on each contact line is essentially constant. This procedure can make processes such as counter-bending, creating a bomb, etc. superfluous.
  • Embossing molds can further advantageously consist of a combination of different materials; in particular, in at least one of the embossing molds, a coating of the thermoplastic material containing the embossing surfaces and having an adhesion promoter layer made of an elastomer can be applied to a steel core.
  • the flow behavior of the materials to be embossed between the embossing dies can be influenced by adding fillers to the elastomeric, thermoplastic or thermosetting materials.
  • a filler can be used in the embossing mold in the elastomer plastic of the embossing surface be added, which is expandable and, for example, changes the geometric structure after a master molding process.
  • the material to be embossed can only flow in certain areas and thus experiences a permanent, high plastic deformation.
  • the same effect can be achieved by appropriate shaping of the embossing molds, in that pinch edges are provided which partially allow the flow process or partially prevent it.
  • a laser is used for direct structuring, by etching in a liquid bath or by removal from the ionized state.
  • direct structuring should be understood to mean direct structuring using lasers or also direct structuring using cutting tools.
  • An embossing mold produced according to the above-described method can be used as a master mold for a counter mold, the counter mold having a master mold surface, for example made of a non-hardened polymer or thermoplastic made thermoplastic, which is molded according to the surface structure of the stamp mold, whereby if necessary, the consolidated surface of the counterform is processed further.
  • a master mold surface for example made of a non-hardened polymer or thermoplastic made thermoplastic, which is molded according to the surface structure of the stamp mold, whereby if necessary, the consolidated surface of the counterform is processed further.
  • embossing tool that is constructed in accordance with the present invention, a three-dimensionally shaped embossing is possible for the first time in the area of the opposing embossing surfaces, since the embossing surfaces do not have to be present on the embossing molds in one plane parallel to the embossing tool axis.
  • layers of the same or different materials can be used.
  • thermoplastic foils, metal foils, etc. can be stamped together.
  • a single layer for example of a thermoplastic material, can also be embossed.
  • Combinations of different manufacturing processes can be used for producing the embossing tools for an embossing mold and a counter mold, such as direct structuring-direct structuring; Direct structuring primary molding process, removal from the ionized state primary molding process.
  • Different materials are also possible for the embossing mold and for the counter-mold, for example molds can be opposed to one another, both of which are made of metal or both of a suitable plastic, or one is made of metal and the other is made of plastic.
  • All known methods can be used to apply the various surfaces or layers to a blank for producing an embossing mold.
  • the preferred processes include, in particular, spraying processes, thermal spraying, fluidized bed sintering, vulcanization of rubber, pouring or the application of Heat shrink tubing etc.
  • All known methods can also be used for structuring the embossing mold or the sleeve. These include, in particular, the area and / or depth-variable laser direct structuring, removal from the ionized state or mechanical engraving.
  • FIG. 1 shows in a partial sectional view how hygiene cellulose wipes are produced from four layers 27, 28, 29 and 30 by means of an embossing tool according to the present invention.
  • the web intake which is caused by the different flow path of the individual webs, is marked with the dimension arrow 31 or 31 '.
  • the different web feed originates from a longer flow path of webs 30 and 27.
  • the point 32 connected by embossing lies deeper than the raised surfaces 27 or 30 of the cellulose cloth.
  • the point 33 connected by the embossing lies deeper than the surfaces 27 or 30 of the cellulose cloth.
  • the raised embossing surfaces 34 and 35 or 36 and 37 do not necessarily lie in one plane and parallel to the embossing mold axes 38 and 39.
  • FIG. 2a shows an embossing mold with an elastic coating 40, in which an expandable filler 41 is embedded, which can be expanded after the shape has been produced, for example by means of an original molding process or sublimation.
  • the subsequent expansion causes a jamming at position 42 for the layer 43 to be embossed and thus enables the web-shaped material to flow without the layers being able to flow outwards.
  • Expanding powders are known, for example, from the production of thermoplastic injection molded parts.
  • FIG. 2b shows an embossing mold with an elastic coating 45, which is provided with pinch edges 46.
  • the crimped edges 46 cause jamming at the point 47 of the layer 48 to be embossed, so that the material can flow without the layer flowing outwards during the embossing. Since the material flows only between the crimped edges 46, this leads to a smaller web feed 49 or 49 '. This results in a permanent, plastic deformation, even for very elastic layer materials.
  • FIG. 3 shows an example of possible steps in a method for producing an embossing mold for an embossing tool according to the present invention.
  • An embossing die blank 50 first receives an etch-resistant coating 51, which is then at the locations to be etched through in terms of volume 52 is removed, for example, by means of a laser. After the first etching process, a relief is created, as shown for example in partial image 3b).
  • the etch-resistant layer at point 53 is now removed, and volume is removed again, so that a first step formation occurs, as shown in FIG. 3c). If the etch-resistant layer 54 is now removed and then removed in terms of volume, a further step is obtained, as shown in FIG. 3d).
  • step configurations can also be achieved in the depressions by re-coating the embossing die blank, FIG. 3e), the etching protection is partially removed and the volume removed again.
  • the step formation can be seen in FIG. 3f) at position 55.
  • Layers that represent a passivating surface can also be removed with the aid of a laser, so that deeper structures can be produced than in conventional etching processes. This is especially true for high-alloy and hardened steels, since the passivation layer is formed during the etching, whereby mainly alloying elements are deposited on the surface to be etched.
  • FIG. 4 shows, in a partial sectional view, an embossing roller 56, with the aid of which a counterform 57 is produced in the master molding process.
  • the counter mold 57 has a surface which is archable and consists, for example, of uncured polymer or thermoplastics which have been thermoformed.
  • the embossing roller 56 already has the structure to be molded, which has been produced, for example, by direct structuring using a laser or removal from the ionized state.
  • the structure of the embossing roller 56 is shaped by the countermold 57 by means of a counter-rotating movement of the individual embossing molds uni their axes 58 and 59.
  • the surface of the counter mold 57 can be processed further by removing disruptive material 61 from the surface, so that the finished embossing surface 62 is formed.
  • FIG. 5 shows an embossing mold in which several materials are combined.
  • an elastomer can be used as an adhesion promoter layer 71 between a thermoplastic 72 and a core 70 made of steel.
  • shrinkage stresses which arise due to different coefficients of thermal expansion during the structuring of the layer 72 can also be compensated for.
  • Shrinkage stresses also occur during operation and can also be compensated for. This avoids mechanical damage during operation.
  • FIG. 6 shows how the subsequent bending curve is already taken into account when the embossing surfaces are at a distance from the embossing die axis when the embossing dies are being produced.
  • the distances 73, 74, 75 of the embossing surfaces to the respective embossing mold axis are adapted, as can also be seen in FIG. 5, such that the surface pressure can be the same in the embossing between all opposing embossing surfaces which act on the sheet-like materials .
  • This procedure can make processes such as counter-bending, creating a bomb, etc. superfluous.
  • a wide variety of motifs can be applied to the cylinder as desired, for example by turning, without problems with different surface pressures along the line of contact of the two embossing dies, between which the layers of web-shaped material lie. surrender.
