Definitions

  • the present invention relates in general to the art of embossing and printing, and more particularly, to an apparatus and method for simultaneously embossing and valley printing elongated substrates such as polymer louvers and the like.
  • Elongated louvers such as vertically and horizontally oriented slates of the type used in window treatment assemblies are well known in the art and commercially available in a wide variety of designs.
  • the formation of louvers usually occurs through a forming machine, such as but not limited to, an extruder which produces an elongated continuous louver from a hot melt thermoplastic material such as polyvinyl chloride (PVC) and the like.
  • PVC polyvinyl chloride
  • the window treatment industry has recognized the desirability of forming a decorative pattern on at least one exposed surface of the louver. By providing various decorative patterns, various effects can be obtained so as to provide a wide variety of products which will appeal to the consumer, as well as satisfying various decorating goals.
  • Kierson, U.S. Patent No. 5,311,814 discloses an assembly for forming or embossing a decorative pattern on at least one exposed surface of an elongated slat preferably of the type used in vertical blinds.
  • the assembly includes a pair of driven rollers which are designed, dimensioned and configured to engage opposite sides of a slat immediately subsequent to its formation by a - 2 - plastic extruder.
  • the exterior surface of one of the rollers has a decorative pattern formed thereon, and when forced into confronting engagement with an exposed surface of the slat, the decorative pattern is transferred by an embossing technique.
  • embossing technique for laminated plastic panels is disclosed in ellen, U.S. Patent No. 3,481,818.
  • U.S. Patent No. 5,339,730 discloses a method for printing and embossing sheets of paper made of cellulose wadding and with two or more plies. The method discloses applying ink to one of the sheets as it travels around a first embossing roller prior to being bonded with a second sheet which passes around another embossing roller. The resulting printed pattern is sandwiched between the two sheets which are glued together.
  • U.S. Patent No. 4,112,189 discloses a process for multicolor valley printing and embossing of flooring material.
  • the apparatus includes a rotatable embossing and printing roll having an engraved surface contour representing a decorative pattern to be embossed and printed on a sheet of flooring material.
  • a plurality of rotatable pattern - 3 - rolls are arranged in operative engagement with the surface of the embossing and printing roll.
  • Each pattern roll is designed to receive a different color ink and to transfer the ink to a discrete surface area of the embossing and printing roll in a manner such that certain portions of the surface area thereof receive one color ink from a single pattern roll and other portions thereof receive overlapping layers of different color inks from at least two pattern rolls.
  • the pattern rolls are formed with raised portions corresponding to predetermined discrete raised surface areas of the embossing and printing roll to which ink from such pattern roll is to be applied. From the foregoing, it can be appreciated that there is the requirement for maintaining proper alignment between the pattern rolls and the engraved surface of the printing and embossing roll. To accomplish this registration, the embossing and printing roll, the pattern rolls, as well as the inking rolls of the ink transfer system are all operatively linked together by a gear train which is driven by a motor.
  • the aforementioned single drive system as disclosed in Terwilliger suffers from a number of disadvantages. For example, it is important that the surface speed of the pattern roll be matched to the surface speed of the printing and embossing roll. Otherwise, an improper layer of ink will be transferred, either being too little or too much, which will adversely impact on the appearance of the resulting printed and embossed material.
  • the disclosed single drive system provides no ability to adjust the individual surface speeds as may be required to accommodate variations in roll diameter, either initially or during the embossing process. There is further disclosed in Snyder, U.S.
  • Patent No. 3,850,095 an apparatus and method for embossing and valley printing of carpets with a hot melt ink.
  • hot melt ink is - 4 - transferred from a pickup roll immersed in the liquefied hot melt ink to a transfer roll. From the transfer roll, the hot melt ink is transferred to a inking roll which is in operative engagement with a printing and embossing roll.
  • Snyder suffers from similar disadvantages noted with respect to Terwilliger in the inability to control the surface speed of the inking roll and printing and embossing roll.
  • An object of the present invention is to provide an apparatus and method for embossing and valley printing elongated substrates using a three roll angular offset gravure printing system.
  • Another object of the present invention is to provide an apparatus and method for embossing and valley printing elongated substrates wherein the surface speed of the rolls may be controlled independently to allow for the accurate inking of the printing and embossing roll with the proper amount of ink transfer.
  • Another object of the present invention is to provide an apparatus and method for embossing and valley printing elongated substrates wherein the printing is accurately aligned with the embossed areas of the substrate.
  • the present invention discloses and describes a three roll angular offset gravure printing system wherein the third roll is also an embossing roll.
  • the embossing roll is backed up with a fourth roll for hydraulic embossing and printing on the substrate surface within the nip formed between the third or fourth rolls.
  • the substrate is in the nature of an elongated louver which is formed from hot extruded PVC material. It is, however, to be understood chat the present invention is suitable for embossing and valley - 5 - printing other substrates for other applications for use in decorative coatings and the like, as well as materials other than PVC.
  • the first roll in the apparatus of the present invention is a pickup roll which picks up ink from a supply thereof, such as an ink bath.
  • the ink is doctored from the pickup roll surface, leaving a precise amount of ink for transfer to a second roll, which is a rubber coated transfer roll having an unpatterned surface. This is achieved without ink smearing by gearing the first and second rolls to a first drive motor.
  • the transfer roll is also maintained at the same surface speed as the surface of the printing and embossing roll, i.e., the third roll, by providing the embossing roll with a separate drive motor that maintains the correct relative speed therebetween.
  • the relative surface speed is measured by independent speed sensors with indicators which allow for controlling the speed either manually or by computer operation.
  • Ink from the transfer roll is transferred through kiss contact with the printing and embossing roll so that only the high points or raised areas on the top surface of the roll become inked.

Abstract

L'invention concerne un appareil et un procédé permettant de gaufrer et d'imprimer en vallée des substrats allongés et se présentant sous la forme d'un système d'impression en creux à trois rouleaux décalés angulairement, lequel système est également conçu pour le gaufrage. L'appareil permet une maîtrise indépendante (164, 152) de la vitesse de surface d'un rouleau de transfert (122) lorsqu'il transfère une couche d'encre à des parties saillantes exposées du rouleau d'impression et de gaufrage (166). Le maintien du rouleau de transfert (122) et du rouleau d'impression et de gaufrage (166) à une vitesse de surface sensiblement identique permet de transférer l'ancre, sans faire de taches, et selon l'épaisseur adéquate pour permettre une impression en vallée sur plusieurs substrats, tels que des persiennes et similaires.
