Definitions
- the process includes the steps of electropolishing the surface of the engraved roller, plate or die, electroplating a deposit of a metal having a high to medium levelling effect and brightness over the entire surface of the roller and plating the roller with a metal characterized by a relatively lower levelling effect, as a finishing coatmg.
- the present invention relates to a new and improved embossed roller, plate or die which is obtained by electropolishing the surface of an engraved roll'er in order to enhance the sharpness of the features of the engraving, electroplating a deposit of a suitable metal having a high or medium levelling effect, such as copper, over the entire surface of the roller and a second plating with a metal having a lesser levelling effect such as chromium, as a finishing coating.
- the new and improved roller thus obtained is capable of reproducing fine and delicate designs from an original pattern thereby providing high fidelity in the reproduction operation.
- the present invention provides a new and useful procedure for modifying embossing rollers, plates or dies so as to produce articles having the desired surface patterns or designs which are characterized by exceptional fidelity in every dimension.
- Using the modified roller of the present process there is obtained a reproduction so accurate and complete in every detail that it is difficult to distinguish the reproduction from the original design.
- the reproduction is so faithful that even weavers imperfections are duplicated with exact fidelity when the master original involves a cloth or like material.
- the embossing roller obtained by the process of the present invention can thus reproduce articles so faithfully that there is scarcely any limitation with respect to the type of design or pattern which the master original may have.
- modified embossed roller obtained by the process of this invention may also reproduce, in a 2- or 3- dimensional configuration, any design or pattern such as that found on the surface of drapery material, upholstery, tablecloth fabric, leather, reptile or animal skin, wood, tapestry, carpeting, crinkle foil, linoleum and the like.
- a new and improved embossed roller by subjecting a machine engraved or electroformed roller to a combination of steps involving l an electropolishing step followed by (2) a bright metal plating step with a metal characterized by a high or medium levelling effect, to produce a combined brightening and smoothing effect on the roller.
- Illustrative metals are copper, iron, nickel, and the like.
- a second plating step which is used as a finishing coating for the roller and the second plating is suitably effected by the use of a metal having relatively lower levelling effect such as chromium or nickel.
- the second plating step provides a hard coating surface which is resistant to corrosion and erosion while at the same time enhancing the textured pattern of the end desired product.
- the order of aforesaid steps is not critical as the electroplating with a metal having a low levelling effect can precede the electroplating step wherein a metal having a high levelling effect is used. These steps can then be followed by the electropolishing step.
- the shape and configuration of the embossing rollers, plates or dies employed in conjunction with the new method of the present invention is not critical and it is to be understood that any roller, plate or die of practically any shape suitable for imparting the desired grain or texture to the material which is to be embossed is acceptable for use in conjunction with the present process.
- the roller, plate or die can be made of a wide variety of materials including ferrous or non-ferrous metals such as aluminum and aluminum alloys.
- ferrous or non-ferrous metals such as aluminum and aluminum alloys.
- the advantages of aluminum rollers are that such rollers are characterized by better heat transfer, easier machining and less weight then steel rollers.
- it is also possible to utilize effectively plastic rollers having a metal coating on the surface and illustrative plastic rollers are those fabricated from polyvinyl chloride, rigid urethanes, and the like.
- embossing rollers, dies, plates and the like are conventional and the particular method employed for engraving is not critical to the success or operability of the present process.
- the embossing rollers, plates or dies can be engraved by many procedures and illustratively, by hand, by machine, chemical or photochemical techniques.
- modified roller, plate or die which can successfully impart a natural grain to paper, aluminum foil, synthetic materials such as polypropylenes, urethanes, cellulose, synthetic fabrics, and the like, and even to a material such as wood.
- the modified rollers obtained by the present process can be applied to any material that can be embossed whether such material is a synthetic or a natural substance.
- modified rollers of the present process when applied, for example, to the reproduction of kidskin, the resulting product is characterized by a glossy and shiny brilliance, an excellent feel or touch; the product looks like a skin which has actually been blended in.
- the present invention accordingly represents an important improvement in the art since it avoids the disadvantages associated with the use of conventional embossed rollers.
- the new and improved process of the present invention involves a combination of steps including l electropolishing the embossed roller, modifying the roller with (2) a bright metal plating and (3) a second metal plating step.
- the metal used in the first plating step in generally ductile and bright having a high or medium levelling effect on the surface of the roller. Suitable metals include for example, copper, nickel or iron. It has been found that the use of copper is most suitable.
- a metal having a relatively lower levelling effect such as, for example, chromium or nickel, is used.
- the electropolishing step is a conventional one involving an anodic treatment over the roller thus producing both a smoothing and brightening effect.
- the electroplating procedures used are also conventional and involve utilizing the roller as the cathode in an electrolytic bath.
- the electroplating enhance the surface characteristics of the roller, plate or die so that said roller imparts to the material to be embossed, a lustrous leatherlike finish.
- Any suitable or conventional electrolyte can be used in the electoplating bath.
- a plurality of electroplating steps is employed in order to secure the desired surface characteristics comparable to those of the original material.
- the first electroplating step is effected by use of a metal having a high or medium levelling effect such as copper followed by a second electroplating step using a metal having a relatively lower levelling effect such as chromium.
- a modified roller, plate or die which is capable of reproducing unusual textured effects and especially those requiring fine and delicate designs, on various substrates such as, for example, vinyl fabrics. It is thus possible to obtain, for the first time, a reproduction of any textured surface characterized by great fidelity and extreme dimensional accuracy. Further, the reproduction capacity of the modified roller obtained by the present process exceeds the limits of machine engraving as there is no limitation with respect to shape, size, design or pattern.
- EXAMPLE A 6 foot embossing roller was engraved with the best smooth kid grain available.
- the embossing effects previously obtained on a polyvinyl chloride fabric were unsatisfactory since the fabric was characterized by a dull-plastic look and there were tool marks noted on the fabric including parallel lines. While there was some improvement in the texture of the fabric by subjecting it to electropolishing, the fabric still did not compare favorably with the natural grain or texture of kid grain.
- the embossed roller composed of a conventional steel such as SAE 1035 was stripped of metals previously plated. The roller was then hung in a tank which was steel lined, said tank functioning as a cathode while the roller functioned as the anode.
- electrolyte contained phosphoric acid and chromic acid
- any electrolyte suitable for electropolishing steel, aluminum or copper can be used depending upon the cylinder metal or material.
- the roller was subjected to a copper flash from a cyanide bath having the following composition and under the following conditrons:
- the plating bath determines the levelling effect i.e., the ability to deposit inrecessed areas.
- the product obtained by use of a modified roller prepared by the foregoing combined electropolishing and electroplating steps is characterized by a glossy, shiny brilliance possessing the touch" and feel of kidskin.
- the product is also characterized by an elegant appearance and simulates, in every detail, the appearance and texture of kidskin leather.
- rollers, dies, and the like can be made of any material having a conductive surface.
- embossing rollers, molds or dies can be used on many material substrates such as synthetic materials, paper, wood, metal, and the like. Still further, as electroytes, various substances: can be suitably employed.
- a method which comprises embossing a substrate with an engraved embossing master surface which has been subjected to the following succession of steps:
- a method according to claim 1 wherein the engraved master surface is a roller, plate or die.
- a method according to claim 1 wherein the levelling action is effected by subjecting the master surface to the electroplating action of copper, or iron.
