Definitions

  • the present invention relates to a method for making decorative emblems, plaques, and the like (hereafter generically called "decorative shapes") which have a cured plastic layer over a decorative surface. More particularly it relates to a method in which a plurality of individual coated shapes are stamped from a single substrate without damaging the plastic coat or deforming the shape during the die cutting operation.
  • U. S. Patent No. discloses a process for mass producing decorative shapes in which a smooth coating of a radiation curable polyurethane composition is applied by flow coating to a foil substrate decorated with a series of designs in the form of individual emblems or plaques and backcoated with a layer of adhesive.
  • a cutting die such as shown in Fig. 3 indivi­dual shapes are stamped from the substrates by pres­sing the shape contiguous with the decorative design with a male punch into a female cutting die. This imparts a domed shape to the decorative emblem.
  • this dome is of aesthetic value, the depth of the dome is difficult to control and the domed shape is difficult to apply to a flat surface or a surface where the radius of curvature is substantially different than that of the dome.
  • a dome is imparted to the shape as it is die cut, it is difficult to obtain decorative shapes having a sharply cut vertical edge, occasion­ally the shape may delaminate, scratch or chip, and there is some edge deformation and silvering of the foil substrate.
  • the adhesive There is also a tendency for the adhesive to ooze from the substrate and contaminate the mold when it is die cut. All of these drawbacks contribute to a reduction in the weather resistance of the cut shape.
  • a typical decorative shape produced in accordance with the present invention and the afore­mentioned U. S. Patent Application is stamped from a laminate including a sheet of aluminum painted or silk-screened on one side with a decorative insignia or graphic which is over coated with a layer of cured polyurethane and coated on the other side with an adhesive composition.
  • the adhesive layer is overlayed with a sheet of release paper.
  • Fig. 1 One exam­ple of this laminate is shown in Fig. 1.
  • the cutting die strikes this laminar structure, due to the relative softness of the polyurethane and the adhesive composition in comparison to the aluminum sheet, the coated substrate moves slightly with the cutting edge of the die. This causes the substrate to bow under the face of the male punch. Bowing involves the drawbacks mentioned above. In particu­lar, bowing irreversibly domes the decorative shape and produces a shape with poor edge characteristics, which is subject to delamination and has poor wea­ther resistance.
  • the present invention provides a method for obtaining essentially flat decorative emblems, plaques and the like with a sharp vertical edge.
  • individual decorative shapes are die cut from a laminated substrate on which a series of decorative designs are reproduced, which designs are overcoated with a layer of cured plastic.
  • the invention uses a cutting die set in which a pressure platform is resiliently mounted in a female cutting die. The pressure platform pre­vents the substrate in the area of the decorative shape from bowing under the punch by sandwiching the shape between the platform and the punch.
  • the pres­sure platform biases the substrate against the male punch with sufficient pressure to prevent it from bowing on the face of the male punch.
  • the male punch forces the substrate into the cutting die by depressing the pressure platform.
  • the tension in the platform mount is adjustable such that the platform provides enough resistance to prevent the substrate bowing without otherwise scratching or deforming the plas­tic coat.
  • the press opens, and releases the substrate.
  • the plat ­form under its resilient mounting returns to its pre-cutting position and insodoing the shape which is now cut from the substrate, is reinserted in the substrate selvage for carriage to a punching station where the shape is ejected from the substrate and collected.
  • a 2-working station cutting die set is employed wherein shapes are simultaneously cut and reinserted into the substrate at one station and punched or ejected from the substrate and collected at the other.
  • the sub­strate from which the shapes are cut and ejected is supported on a resilient table for both operations.
  • the mouth of the female cutting die is provided with a steel rule knife.
  • the knife mini­mizes the cutting force and delamination, reduces aluminum burring, and provides a sharp vertical edge and also cleanly cuts adhesive and release paper.
  • the present invention is a process for forming decorative shapes such as that illustrated in cross-section in Fig. 1.
  • a typical shape com­prises a substrate 10 which is coated on the back side with a layer of adhesive 12.
  • a sheet of release paper 14 releasably laminated to the layer of adhesive 12.
  • the top or graphic surface 13 of the substrate 10 is preferably provided with a layer of primer or a subbing layer 16 on which a decora­tive design or insignia 18 is painted or silk screen printed.
  • This design is overcoated with a clear plastic layer 20 which beautifies the image and imparts wear and weather resistance to the object.
  • Plastic coating 20 is optionally overcoated with a further protective film 22 such as a film of poly­ethylene.
  • FIG. 2 A composite for mass producing these shapes is shown in Figure 2 wherein an array of designs 24 is formed on graphic face 25 of a sheet of substrate 26.
  • the design areas present a laminar construction as in Figure 1, however, for simplicity only the plastic coat 28 is separately shown and the lami­nated substrate is generally designated 26 with the understanding that it represents the laminated sub­strate structure as shown in Fig. 1.
  • Alternatives to coating local areas of the substrate are to coat the entire sheet of substrate 26 or only the indivi­dual designs 24 with plastic.
  • the designs may be formed with an edge, dyke or other shapes defined peripheral edge which halts the flow of the plastic at the design edge.
  • the simpler technique however is to deposit an amount of plastic on the design which, when it flows to completion, coats the design and a small amount of the area which immediately surround it, as shown in Fig. 2.
  • the substrate upon which the fluent plastic is coated may be a plastic or metal foil, preferably an aluminum foil 0.003 to 0.020 inch thick.
  • the foil substrate is decorated with an appropriate design or series of designs. More commonly, a series of designs in the form of individual emblems or plaque shapes will be applied to the foil sheet. With a metal foil, the series of designs is preferivelyably applied by silk screen or lithographic printing then the design is enhanced by embossing select areas; although, other means for forming the decora­tive designs may also be used.
  • the foil may be embossed to give a three dimensional effect to the emblem.
  • any suitable primer may be used, such as a silane primer.
  • the decorated-primed substrate is then placed upon a vacuum mat which is situated upon a horizontal vacuum table such as that shown in commonly assigned U. S. Patent No. 4,034,708. Vacuum is drawn against the bottom surface of the foil through the mat to hold the substrate flat and horizontal.
  • the flow characteristics of the fluent plastic and the liquid wettability of the substrate are used to control the spread of the plastic so that it is contiguous with predetermined areas of the foil as well as being uniformly thick. It is also possible to control the plastic flow by use of sharply defined peripheral sides for the substrate or defined areas of the substrate as disclosed in Serial No. 54,548.
  • Flow coating is a path-wise desposition. That is, a multiple orifice nozzle (or nozzles) is passed over the decorated-primed surface of the foil at a steady speed as the substrate is held statio­nary.
  • the number of orifices used may vary depend­ing on the width of the path to be laid down.
  • the thickness sought is between approximately 0.020 to 0.040 inch.
  • the plastic is preferably a fluent polyur­ethane of two component parts (polyol and isocya­nate) which are mixed immediately prior to coating and cure upon heating.
  • a polyurethane of this type is disclosed in commonly assigned U. S. Patent No. 4,100,010.
  • That mixture is one of a poly­ether polyol component ("A"), which may be a difunc­tional, trifunctional and/or tetrafunctional poly­propylene glycol containing a suitable catalyst, and a diisocyanate component (“B”) such as an aliphatic diisocyanate.
  • a catalyst such as a lead or mercury material is used since it promotes a slow cure at room temperature so as to allow time for full flow of the liquid polyurethane before setting.
  • an example of the diisocyanate is Hylene W from E. I.
  • the polyether polyol may be one or more of the Pluracol materials (P-410 or TP-440) from BASF Wyandotte. It may also be a poly­ether-polyester polyol combination, use of the poly­ester polyol making the cured polyurethane more flexible.
  • the ratio of components A:B is preferably 50-60:40-50.
  • a polyester polyol or polylactone polyol could be used in place of the polyether polyol.
  • the polyurethane may be com­pounded from among components listed in the patent as is known to give a more flexible cured plastic.
  • the bond to the substrate remains strong, it is desirable in this invention to have a somewhat flexible plastic coat so that the emblem or plaque may be conformed.
  • some decorative automobile panels are applied to a curved surface.
  • the present invention it is possible to con­form the cured plastic coated panel to that surface.
  • the coated substrate After curing, the coated substrate is cooled and removed from the vacuum table.
  • Individ­ual emblem or plaque shapes are stamped out by a cutting die around the particular emblem or plaque shape. It has been found that by preventing the coated substrate from bowing while die cutting the decorative shape it is possible to obtain a shape which is essentially flat (except in areas where the shape has been pre-embossed to give depth to the decorative pattern) and which has a sharp vertical edge which resists delamination and provides good weather and wear resistance.
  • the shapes are cut from the coated, lami­nated substrate using a die set such as that illus­trated in Figs. 4 or 5. The die sets shown in Figs.
  • a conventional cutting die set is shown in Fig. 3A.
  • This die set comprises a punch holder 40 which is mounted in die cutting relation with a die holder 42.
  • Punch holder 40 is coupled to a press ram (not shown) by shank 43, and die holder 42 is clamped or otherwise mounted to the press bed at ears 45.
  • the punch holder 40 and die holder 42 are aligned by a plurality of guide posts and guide bushings (not shown).
  • the press is mechanically actuated but a hydraulic press may also be used.
  • a male punch 46 is mounted on the punch holder 40 with a surrounding stripper plate 44.
  • the plate 44 contiguously frames the male punch 46 and is mounted for resilient reciprocation on a set of spring-shoulder screw assemblies comprising die springs 49 and 51 carried on shoulder screws or stripper bolts 48 and 50.
  • a set of spring-shoulder screw assemblies comprising die springs 49 and 51 carried on shoulder screws or stripper bolts 48 and 50.
  • two shoulder screws are shown, another pair of shoulder screws, located on the back side of the stripper plate is not seen in this schematic sectional view.
  • a threaded connection is provided between the plun­gers 48 and 50 and the stripper plate 44.
  • the stripper plate 44 holds the substrate in place during the cutting operation and cleans any selvage clinging to the punch 46.
  • the position of the stripper plate may be lowered or raised by inserting a shim under the shoulder or body of the shoulder screw. To increase spring pressure, a shim may be inserted under the die spring or a higher pressure die spring can be used.
  • Die holder 42 carries a female die 54 having a cutting edge 56, a die face 58 and a female die cavitiy 60.
  • the female die 54 is positioned on the die holder 42 such that the female die cavity 60 opens on an outlet passage 62 formed in the holder 42.
  • Shapes having a laminar construction such as shown in Fig. 1 are cut from a substrate by positioning the substrate 26 on the face 58 of the female die 54 with its graphic side 25 down and its design area in alignment with the mouth or cutting edge 56 of the die.
  • the press is closed as shown in Fig. 3B, the substrate 26 is engaged by the stripper plate 44 and the punch 46.
  • the punch 46 descends into the die cavity 60, the springs 49 and 51 on the shoulder screws 48 and 50 are compressed and the area of the substrate contiguous with the design is engaged by the stripper plate 44. Due to the relative softness of the layers on each side of the substrate 26, the substrate is pulled into the die cavity 60 and bows under the punch 46 as shown by the bow 68 in Fig. 3B.
  • bowing is prevented by holding the substrate flat on the punch face using a pressure platform which is resiliently mounted in the female cutting die. Furthermore, because cut shapes can no longer be collected from an opening in the base of the female cutting die cavity, they are reinserted in the substrate selvage by the platform after they are cut and ejected by a separate operation which is conveniently performed at another working station in the die set.
  • the die set comprises a punch holder 80, a die holder 82, a right working station 84 and a left working station 86.
  • the shape is cut from and reinser­ted into the substrate 26.
  • the cut shape is ejected from the substrate by a punch.
  • the die set is mounted to the press ram by shank 85 and fixed to the press bed at ears 87.
  • the right station 84 includes a female cutting die 90 which is mounted on the die holder 82.
  • the female cutting die comprises a die cavity 92 in which a pressure platform 94 is resiliently mounted on a spring and shoulder screw assembly comprising spring 96 and shoulder screw 98.
  • a plurality of spring shoulder screw assemblies are used to support the platform depending on the size of the shape cut.
  • the shoulder screw 98 is threaded and screws into the platform 94.
  • the platform in the die cavity and the tension on the spring 96 can be adjusted to provided just enough pressure to prevent the substrate from bowing without deforming the plastic coating over the graphic using shims in a manner analogous to that previously described for the stripper plate 44 in Fig. 3.
  • the mouth of the die cavity 92 is equipped with a knife 100.
  • a punch 102 is mounted on the punch holder 80 and framed by a contiguous stripper plate 104.
  • the stripper plate 104 is mounted on a set of four spring shoulder screw assemblies wherein two assemblies are shown in the view with springs 106 carried on shoulder screws 108 which are threaded at the bottom where they connect to the stripper plate 104. Engagement of the stripper plate is adjusted as earlier described.
  • the left station 86 comprises a second punch 110 mounted on the punch holder 80 and a female die 112 having a die face 114 which is mounted on the die holder 82 such that the die cavity 116 opens into a collection passage 120 formed in the die holder 82.
  • Punch 86 is framed by a stripper plate 115 which is mounted for reciproca­ting movement on spring-shoulder screw assemblies 115a and 115 b .
  • Plate 115 functions analogous to plate 104 and holds the substrate flat as the cut shape is ejected and removes selvage from the punch 110.
  • the pressure platform 94 is shown resiliently mounted on a spring shoulder screw assembly, those skilled in the art will understand that the spring shoulder screw assemblies illustrated herein may be replaced by other types of resilient mounts including rubber blocks and compressed air or hydraulically actuated cylinders.
  • Fig. 4b Operation of the die press is shown in Fig. 4b wherein the substrate 26, which typically has an array of cured plastic coated designs thereon as shown in Fig. 2 is positioned in the right station 84 with its graphic side 25 facing the punch 102 and its design contiguous with the cutting edge 100 of the die.
  • the pitch of the designs on the substrate is such that a second cut design is simultaneously located over the die 112 in the left station as the first design is cut.
  • the size of the die assemblies in the right and left working sta­tions usually dictate that a third cut design be idle between the right and left station as the cutting and ejecting operation proceed.
  • the punch 102 engages the substrate 88 and presses it against the pressure platform 94.
  • the tension in the spring 96 is such that the pressure platform 94 resists the descent of punch 102 with sufficient tension to prevent the substrate 26 from bowing under application of the punch 102 without otherwise scratching, compressing or deforming the design shape 24 or its clear plas­tic coating 28.
  • the tension spring 96 and the pressure in platform 94 is adjusted using shims or through the selection of the die spring, such that the substrate is not distorted by cutting and the cut part is returned to the selvage for carriage to the ejecting station. If the spring tension is too much, the part is distorted, if it is too low, it is not returned to the selvage.
  • the platform 94 is depressed below the upper edge of the knife 100 and the substrate 26 is urged against the knife 100 whereupon a decorative shape 126 is cut from the substrate 26 and forced into the female die cavity 92.
  • the stripper plate 104 engages the portions of the substrate 26 surrounding the shape 126 to prevent those portions from angling around the knife edge 100 and to assist in obtaining a sharply cut vertical edge.
  • the press After cutting decorative shape 126 from the substrate 26, the press opens and punch 102 disenga­ges the substrate. As pressure on platform 94 is released, the platform returns to its original position slightly above the edge of the knife 100 and insodoing reinserts the shape 126 into the substrate 26. At this time, stripper plate 104 is still in pressing engagement with the substrate such that the substrate does not cling to the male punch 102 and the platform 94 is able to reinsert the shape 126 into the substrate without lifting the substrate off the face of the female cutting die.
  • Fig. 4 illustrates a completely automated system in which decorative shapes are continuously cut at the right working station and ejected from the substrate at the left working station with each stroke of the die set, the ejection operation at the second station can be performed manually. In this case, a cutting die set having only the right station 84 produces a substrate from which the cutout shapes can be pushed, for example, by hand.
  • Figs. 5A and 5B illustrate another embodi­ment of the invention.
