Definitions

  • the invention relates to a device of the type specified in the preamble of claim 1 and a method for producing this device.
  • rollers of this type usually have rollers with a profiled surface, between which the sheet-like material to be processed - paper, cardboard, plastic films etc. - runs and which press their surface profile into the material.
  • rollers usually have steel rollers, especially with chrome plating.
  • the publication DE 41 25 996 Cl describes a heatable embossing roller with segments arranged next to one another for processing plastic films.
  • embossing structures are to be produced which require the embossing tools to be shaped substantially differently from the rotationally symmetrical shape, their manufacture from the customary, highly wear-resistant materials also becomes very complex.
  • the invention is therefore based on the object of specifying a device of the type mentioned at the outset which is suitable and inexpensive to produce for processing low-strength materials, in particular filter nonwovens, and a method for producing this device.
  • the invention includes the knowledge that, on the one hand, to produce depressions and / or elevations of greater height in sheet-like materials of low strength, to avoid damage to the material to be processed, and to guarantee acceptable tool costs (in the as is well known, production costs and life expectancy), on the other hand, tools with a well-defined radial strength profile are to be provided.
  • This radial strength profile should be selected so that the tool has a relatively low hardness or strength from the outer circumference to at least approximately the maximum embossing depth, but then this increases sharply radially inwards.
  • the strength in the edge area must be selected in accordance with the material to be machined so that precisely shaped, permanent recesses or elevations are formed and tool wear is limited.
  • the shape and strength of the tool in the inner area (the tool core) must be so high that the tool as a whole remains stable in the embossing process even after prolonged use.
  • a preferred embodiment is that the core has the shape of a hollow cylinder.
  • a rotationally symmetrical core By choosing a rotationally symmetrical core, good concentricity of the embossing roller is advantageously achieved.
  • a rotationally symmetrical (cylindrical or hollow cylindrical) core can also be manufactured easily and inexpensively.
  • the circumferential surface of the core can be profiled, ie the shape of the depressions and / or elevations to be formed in the material to be machined can be predetermined entirely or partially in the shape of the core.
  • the layer of lower strength can additionally have areas of different thickness and thus the profiling of the core - picking them up - reinforcing them.
  • it can also be applied as a (damping) layer of constant thickness.
  • the average thickness of the profiled layer is at most 1/20 of the average diameter of the embossing tool.
  • An embodiment of considerable practical importance in the production of packaging material or filter inserts for fluid filters is one in which the profiled layer has cam-like elevations and / or depressions arranged non-rotationally symmetrically for impressing complementary depressions and / or elevations in has the sheet material.
  • the core consists of metal, in particular aluminum, brass or steel, and the profiled layer of plastic, in particular a polyurethane material.
  • a plurality of embossing tools are advantageously arranged next to one another on the support tube, the cores having essentially the same diameter and the profiled layers essentially the same thickness to have.
  • the profiled layer can consist, for example, of a strip of the material of lower strength which is glued to the core.
  • a preferred embodiment consists in that the profiled layer is cast or injection-molded onto the core in a casting or injection mold.
  • This method specified in claim 10 can be carried out particularly elegantly if a polyurethane material is used as the plastic to obtain the profiled jacket shape. Its strength can easily be adjusted to the conditions of the specific embossing process to be carried out with the tools produced by suitable selection and mixing of the monomers and, if appropriate, fillers.
  • an epoxy resin material can be used as the plastic to obtain the profiled shell shape.
  • the original mold used in the claimed process can preferably be produced from aluminum, which can be comparatively easily brought into the required, complicated shape.
  • the claimed device represents a stamping device that can be provided quickly and cost-effectively, in particular for forming stampings with the highest precision in relatively soft materials that cannot be produced by rotationally symmetrical roller profiles. Such embossings are required, for example, in filter manufacture.
  • the claimed method which takes up and implements the construction principle of the device in terms of process technology, represents an efficient and inexpensive manufacturing process.
  • FIG. 1 shows a schematic perspective illustration of an embodiment of the device according to the invention
  • FIGS. 2a and 2b are schematic cross-sectional representations of an embossing roller in two embodiments and
  • Figure 3 is a schematic diagram of the method for manufacturing the device.
  • FIG. 1 schematically shows how a web 1 made of plastic foam material, which is to be provided with a number of different embossing patterns, passes between two embossing rollers 2 and 3, which are each fixed to a hollow shaft 4 or 5, and with this in the direction of rotation indicated by the curved arrows.
  • embossing rollers are shown in the figure from various embossing rings or segments which are axially pushed onto the shaft 4 or 5 and are rotatably held on the latter by means of tongue and groove, with only the upper embossing shaft 2 being shown in FIG. 1 for the sake of clarity all five rings 2a to 2e, from the lower one, through the leaking material web largely covered, embossing shaft 3, however, only the rings 3d and 3e are shown. (In practice, the ratio of the width to the diameter of the rings can deviate considerably from the illustration given, and they do not have to be lined up in a row.)
  • All rings or segments are - what is shown in the figure with the reference numerals 21e and 22e or 31e and 32e only for the rings 2e and 3e - made of a hollow cylindrical aluminum core and one on its outer surface, surrounding it, cast-on polyurethane jacket.
  • the figure shows a configuration in which all rings 2a to 2e produce different embossed patterns in the material web 1, which runs out of the device as an embossed web 1 '.
  • embossing roller is not used, but generally the same, periodically repeating pattern is provided over the entire width.
  • These are from left to right: a fine, irregularly corrugated groove, a raised one , continuous bead, a recessed, continuous bead, hemispherical impressions and prismatic impressions.
  • the rings of the lower embossing shaft 3 each have an embossing contour complementary to the rings of the upper embossing shaft 2 in or on the PU jacket.
  • the embossing pattern in particular if the embossing pattern has only a small depth and should only be present on one surface of the web - the lower embossing shaft should also be smooth.
  • the contours of the segments can also be considerably higher in relation to the thickness of the material web to be processed, so that the embossed elevations and depressions are much more pronounced and have regular walls.
  • FIG. 2a and 2b show two embossing rollers of the type shown in FIG. 1, each in a special embodiment of the core-shell composite, in cross section.
  • the ring 20a pushed onto a hollow cylindrical shaft or a displacement tube 40 and held there in a rotationally fixed manner with a tongue-and-groove connection 41 consists of a rotationally symmetrical steel disc 201a with a cast PU Jacket 202 with a non-rotationally symmetrical embossing contour 202a, which is formed in its entire height from the PU material.
  • FIG. 2b shows an embossing shaft with a similar embossing contour, in which a ring 20b held on the shaft 40 by means of the tongue and groove connection 41 is made of a non-rotationally symmetrical brass disk 201b, into which the course of the embossing contour is incorporated, and one on the same Is circumferentially glued on plastic strips 202b of constant thickness.
  • FIG. 3 shows the method for producing a device using the structure shown in FIGS. 1 and 2a illustrated with a flow chart of the most important process steps.
  • the required embossing contour of the tool is calculated on the basis of the desired surface profile la of a material web 1 to be embossed with the aid of a computer R.
  • the calculated surface profile is converted into an aluminum master form U of the embossing tool by means of a numerically controlled machine tool NC.
  • the optimal diameter of the core 201a of the tool (embossing ring) 20a to be produced is determined , this is produced on a lathe D and provided with the groove for the tongue and groove connection.
  • a permanent form frame FR with a cylindrical recess is produced in accordance with the greatest radial extent (with an addition calculated with the aid of the computer R) and the height of the original form u - again made of aluminum.
  • the original form U is concentrically inserted with a release agent and the space between the frame FR and the original form U is poured out with plastic.
  • the form F for producing the embossing rings is formed in this way.
  • the core 210a is inserted into the mold F after it has been provided with a release agent, the intermediate space is filled with a urethane mixture and the latter is polymerized, the shell 202a which is firmly connected to the core and carrying the embossing contour and the embossing together with the core ⁇ forms ring 2a, which is pushed onto the shaft 40 and fastened by means of the tongue and groove connection.
  • the embodiment of the invention is not limited to the preferred embodiment described above. Rather, a number of variants are conceivable which make use of the solution shown, even in the case of fundamentally different types.
  • materials other than those specified can be used to achieve the required strength profile; this also applies to the molding materials.
  • the embossed profiles shown and the materials mentioned as goods to be processed are also to be understood as examples only.
