Definitions

  • This invention concerns a method to produce decorative lining sheet for furniture elements and lined elements thus produced for furniture items of a container type, such as cupboards, etc., as set forth in the respective main claims.
  • this invention concerns a method to produce a decorative lining sheet which is applied to suitably shaped filler cores so as to form lined elements for furniture items of a container type.
  • the invention is applied to the furniture industry and especially to the production of lined elements for furniture items of a container type, the elements including a filler core of compressed wood chips, medium density fibreboard or foamed material and having their front surface smooth or shaped with mouldings, cornices, ornaments, etc.
  • the lined elements made for furniture items of a container type by the method according to the invention can be used in the production of furniture either as sidewalls or work surfaces, or as small doors and/or doors for cupboards, etc.
  • the plastic material most commonly used nowadays is PVC.
  • the PVC sheet is supplied at present in rolls and is printed with a roller that prints the desired decorative design on the PVC.
  • the decorated PVC sheet is varnished thereafter for protective purposes and is possibly embossed to obtain in relief the imprint of the design, with a view to designing the pores of the wood, for instance.
  • the decoration and colours produced on the PVC sheets possess a definition which is not always satisfactory from an aesthetic point of view.
  • the PVC sheet has to be deformed in the hot state so as to adhere to these complex surfaces.
  • This deformation produces stretching and division of the design and/or colours into small grains with an effect which may make the finished product unacceptable to users.
  • the purpose of this invention is to provide a method for the production of decorative lining sheets for lined elements for use in furniture items of a container type and also to provide the lined elements for furniture items of a container type thus produced.
  • lined elements can be employed as doors, work surfaces, walls, etc. in the construction of the furniture items of a container type.
  • the decorative lining sheet consists of a neutral sheet of styrene resin or polyolefin which is decorated thereafter according to one of the methods described hereinafter.
  • styrene resin employed may be, for instance, polystyrene, methacrylate or ABS, whereas the polyolefin used may consist, for instance, of polythene or polypropylene with some technical-productive contrivances according to the application in question.
  • the neutral sheet of polystyrene or polyolefin is produced with techniques of the state of the art, for instance by extrusion of the granules of resin; the sheet thus obtained is then decorated with the desired decorative design.
  • the decorated sheet of polystyrene or polyolefin then undergoes a varnishing step for protective purposes and is possibly embossed to produce designs in relief on its surface.
  • the step of decoration of the sheet of polystyrene or polyolefin is carried out by transfer printing of the type employed for printing decorations on woven fabrics.
  • Transfer printing methods using dry heat of the Sublistatic, Thermochrome, conventional heat or infrared vacuum types may be employed.
  • the desired decorative design imparted in a counterpart form to a supporting substratum consisting, for instance, of a sheet of polythene or paper is transferred by the combined action of heat and pressure or by sublimation of dyes onto the sheet of polystyrene or polyolefin.
  • the transfer of the decorative design from the supporting substratum to the sheet of polystyrene or polyolefin is carried out by calendering, for instance, by passing the two facing sheets through a pair of suitably heated rollers pressed together.
  • the fields of pressure employed in the method according to the invention are between about 8 and 15 bar on the pressure roller, while the working temperature in the zone of contact is between about 105° and 130°C.
  • the step of decoration of the sheet of polystyrene or polyolefin is carried out by the rotogravure method used, for instance, to print newspapers.
  • Rotogravure for transfer of decorative designs to the sheet of polystyrene or polyolefin differs substantially from the printing of newspapers owing to the substantial difference of the inks employed, the working temperatures during drying of the inks and the different speeds of application.
  • the decorative designs in the method according to the invention are etched directly on the roller.
  • the ink employed to produce the design has to be suitable to produce designs on the sheet of polystyrene or polyolefin.
  • the type of ink employed in the method according to the invention is different from those used at present in transfer printing on woven fabrics or hides owing to its greater mechanical strength and to its special feature of not becoming yellow in the long term.
  • the lining sheet thus produced is then applied by means of a method of the state of the art to a suitably shaped filler core consisting of compressed wood chips, medium density fibreboard or foamed material.
  • the costs of production of the decorative lining sheet are considerably less inasmuch as the cost of the roller to produce the decoration on the supporting substratum is much lower than the cost of the roller used to print the PVC.
  • the designs produced with this method possess a much better definition than those which can be produced with the methods of the state of the art, and the decorative lining sheets have aesthetic characteristics better than those of the present PVC decorative lining sheets.
  • the decorative lining sheet produced with the method according to the invention is such that, even when the sheet is deformed to adhere perfectly to the surface of the filler core, the design does not separate into small grains; this is so because the ink does not stretch even when the sheet of polystyrene or polyolefin is stretched.
  • the reference numbers 10-110 in the attached figures denote generally a method to produce decorative lining sheet 11 employed to decorate a shaped filler core 21 so as to constitute an element for furniture items 12 of a container type, such as cupboards for instance.
  • the decorative lining sheet 11 consists of a neutral sheet 13 of polystyrene or polyolefin, to which the desired decoration is applied with the method according to the invention.
  • a design which reproduces a counterpart of the decoration to be produced on the neutral sheet 13 of polystyrene or polyolefin is made 15 by rotogravure on a supporting substratum consisting, for instance, of a sheet of polythene or paper 14.
  • the decorated sheet 11 of polystyrene or polyolefin then undergoes a varnishing operation 17, whereby a layer of varnish to protect the design is applied by techniques of the state of the art.
  • the decorated sheet 11 of polystyrene or polyolefin is now applied 20 to the filler core 21 with techniques of the state of the art so as to obtain a lined element 12 for furniture items of a container type, such as cupboards etc.
  • the design is transferred to the neutral sheet 13 of polystyrene or polyolefin by a rotogravure operation 22.
  • the transfer of the decoration to the neutral sheet 13 of polystyrene or polyolefin is performed with a suitably etched roller, which leaves the ink on the support to be decorated.
  • the decorated sheet 11 of polystyrene or polyolefin undergoes thereafter operations of varnishing 17 and possible embossing 18, as described above, before being fitted 20 to the filler core 21.
  • Fig.3 is a diagram of a plant 23 to produce lined furniture elements 12 according to the method of Fig.1.
  • a sheet of polythene or paper 14 fed from a first roll 24 is brought to cooperate with a printing roller 28 to apply the decoration to one of its faces and is then brought to cooperate with a neutral sheet 13 of polystyrene or polyolefin fed from a second roll 25.
  • the sheet of polythene or paper 14 and the neutral sheet 13 of polystyrene or polyolefin are passed, face to face, between a pair of suitably heated calendering rolls 26 pressed together.
  • the fields of pressure used in the method according to the invention are between about 8 and 15 bar on the pressure roll, while the working temperature in the contact zone is between about 105° and 130°C.
  • the design is transferred from the sheet 14 of polythene or paper to the neutral sheet 13 of polystyrene or polyolefin owing to the heat and pressure.
  • the sheet 14 of polythene or paper is now without any decoration and is separated from the decorated sheet 11 of polystyrene or polyolefin.
  • the sheet 14a of polythene or paper, now without any decoration, is re-wound on an appropriate take-up roll 30 for subsequent removal, while on the other hand the decorated sheet 11 of polystyrene or polyolefin is brought into cooperation with a varnishing means 27.
  • the decorated sheet 11 of polystyrene or polyolefin cooperates with an embossing roll 19 before being wound up to form a wound decorated roll 29 of polystyrene or polyolefin 11.
  • This decorated roll 29 of polystyrene or polyolefin 11 is employed in plants to line filler cores 21, whereby the decorated sheet 11 of polystyrene or polyolefin is applied, for instance by adhesives, to the filler core 21 to produce a lined element 12 for furniture items of a container type according to the invention.
  • the wound decorated roll 29 of polystyrene or polyolefin is unwound to cover a filler core 21, to which a layer of thermo-activated adhesive has been applied beforehand.
  • the filler core 21 on which the decorated sheet 11 of polystyrene or polyolefin is supported is brought to cooperate with a press 31, for instance, of a type with a suitably heated diaphragm, which deforms the decorated sheet 11 of polystyrene or polyolefin so as to make it adhere to the outer surface of the filler core 21.
  • the filler cores 21 are fed on a conveyor belt 33.
  • the decorated sheet 11 of polystyrene or polyolefin now adhering to the filler core 21 is then sheared by a momentarily activated shears 34, and the lined filler core 21 is sent to a trimming station 32 to provide a lined furniture element 12.
