Werkwijze en middel voor het maken van sculpturen en reliefs aan meubelen, deuren enz.Method and means for making sculptures and reliefs on furniture, doors, etc.

Aanvrager: Gerrit Jan van Rossem, te Westdorpe.Applicant: Gerrit Jan van Rossem, in Westdorpe.

De onderhavige uitvinding heeft betrekking op een werkwijze en een middel voor het maken van sculpturen, reliefs en versieringen aan meubelen, deuren, kasten enz., met behulp van een op een polymere kunststof gebaseerd mengsel, dat op natuurlijk hout gelijkt.The present invention relates to a method and a means for making sculptures, reliefs and decorations on furniture, doors, cabinets, etc., using a polymeric plastic-based mixture resembling natural wood.

5 De werkwijze heeft in het bijzonder betrekking óp een werkwijze voor het reconstrueren en/of repareren en/of geheel of gedeeltelijk nabootsen van antiek houtsnijwerk voor ornamenten op panelen van kastwanden, deuren en betimmeringen.The method relates in particular to a method for reconstructing and / or repairing and / or mimicking in whole or in part antique carvings for ornaments on panels of cabinet walls, doors and paneling.

Werkwijzen voor het opnieuw vervaardigen van dergelijke ornamenten van 10 houtsnijwerk in hun geheel of van delen daarvan, die door beschadiging verloren zijn gegaan, zijn bekend.Methods for remanufacturing such carvings ornaments in whole or in parts thereof which have been lost due to damage are known.

Het nadeel van de bekende werkwijzen is, dat zij bijzonder tijdrovend en arbeidsintensief zijn, aangezien zij geheel of grotendeels op handarbeid berusten en een grote manuele vaardigheid vereisen.The drawback of the known methods is that they are particularly time-consuming and labor-intensive, since they are wholly or largely manual labor and require great manual skill.

15 Her repliceren van sculpturen en ornamenten door middel van industriële vormgevingsmethoden zoals persen en vacuumvervormen heeft het nadeel dat het machinale werk door het visuele uiterlijk of althans door betasten daarvan te onderscheiden is van origineel houtsnijwerk, doordat het oppervlak niet de kenmerken van houtsnijwerk bezit.Replicating sculptures and ornaments by means of industrial design methods such as pressing and vacuum forming has the drawback that the mechanical work can be distinguished from original wood carvings by the visual appearance or at least by touching them, because the surface does not have the characteristics of wood carvings.

20 Gezocht werd naar een werkwijze waarmede de genoemde nadelen kunnen worden ondervangen en werkstukken kunnen worden verkregen die zonder chemisch onderzoek niet van oorspronkelijke ontwerpen zijn te onderscheiden en toch met behulp van weinig tijdrovende arbeidsgangen kunnen worden vervaardigd . 1 8303947A method has been sought which can overcome the above-mentioned drawbacks and obtain workpieces which cannot be distinguished from original designs without chemical research and yet can be manufactured with little time-consuming processes. 1 8303947

Gevonden werd een werkwijze als in de aanhef vermeld, die volgens de uitvinding is gekenmerkt doordat men een mal met een negatief oppervlak van het oorspronkelijke of het gewenste model vervaardigt uit met textielve- J 4 - * -2- zels versterkte epoxyhars met amineverharder,indien het oorspronkelijke stuk onvolledig of beschadigd is, dit bijwerkt met hetzelfde mengsel van textielvezel-versterkte epoxyhars met verharder, en de mal vervolgens geheel laat uitharden.A method as mentioned in the preamble was found, which according to the invention is characterized in that a mold with a negative surface of the original or the desired model is manufactured from epoxy resin reinforced with textile fibers with amine hardener, if the original piece is incomplete or damaged, it updates with the same mixture of textile fiber reinforced epoxy resin with hardener, and then allows the mold to fully cure.

5 Na het volledig uitharden, waarvan de tijdsduur wordt bepaald door de temperatuur en die wordt vastgesteld door bevoelen met een houten staafje, wordt het inwendige oppervlak van de mal geheel bestreken met een dunne laag van de vloeibare epoxyhars met verharder gemengd met zuiver kwarts-zand, waarna men weer laat uitharden en daarna het oppervlak bestrijkt 10 met een niet-polair vormlossingsmiddel.5 After complete curing, the time of which is determined by the temperature and determined by feeling with a wooden rod, the internal surface of the mold is completely covered with a thin layer of the liquid epoxy resin with hardener mixed with pure quartz sand then allowed to cure again and then the surface is coated with a non-polar mold release agent.

Dit wordt goed uitgewreven.This is well rubbed out.

Daarna vult men de zo verkregen negatieve mal met polyurethaanhars met vulmiddel in houtkleur laagsgewijs afgewisseld met een vullingslaag van polyurethaanhars met zuiver kwartszand en naturel textielvezels.The negative mold thus obtained is then filled with polyurethane resin with filler in wood color, alternated in layers with a filling layer of polyurethane resin with pure quartz sand and natural textile fibers.

15 Na het uitharden van de polyurethaanhars wordt het vormstuk uit de mal getild, goed afgewreven en verder als een houten werkstuk behandeld door polijsten en boenen met boenwas.After the polyurethane resin has hardened, the molding is lifted out of the mold, rubbed well and further treated as a wooden workpiece by polishing and polishing with wax.

Het oppervlak van het werkstuk vertoont nu nauwkeurig hetzelfde patroon van houtnerf en onregelmatigheden als het natuurlijke hout.The surface of the workpiece now shows exactly the same pattern of wood grain and irregularities as the natural wood.

20 De uitvinding wordt nader toegelicht aan de hand van de bijgaande tekening.The invention is further elucidated with reference to the annexed drawing.

Deze toont een verticale doorsnede van de mal met daarin het werkstuk tijdens de vervaardiging volgens de uitvinding.This shows a vertical section of the mold containing the workpiece during the manufacture according to the invention.

In de figuur is (1) de laag epoxyhars met textielvezels, (2) de laag epoxyhars met kwartszand, (3) het laagje vormlossingsmiddel en (4) de 25 houtkleurig ingekleurde en gevulde polyurethaanhars en (5) de polyurethaanhars met kwartszand en textielvezels.In the figure, (1) is the layer of epoxy resin with textile fibers, (2) the layer of epoxy resin with quartz sand, (3) the layer of mold release agent and (4) the wood-colored and filled polyurethane resin and (5) the polyurethane resin with quartz sand and textile fibers.

De uitvinding omvat tevens de volgens de beschreven werkwijze verkregen mal en de in deze mal verkregen werkstukken, alsmede de toepassing daarvan, in het bijzonder voor binnenarchitectuur, woninginrichting, herstel 30 van antiek houtwerk en andere oudheden en kunstvoorwerpen, en voor het fabriceren van deuren en lambrizeringen.The invention also includes the mold obtained according to the method described and the workpieces obtained in this mold, as well as the use thereof, in particular for interior architecture, home furnishings, restoration of antique woodwork and other antiquities and works of art, and for the manufacture of doors and paneling.

Het uiterlijk van de volgens de beschreven werkwijze verkregen panelen, 8303947 · 4 / -3- 1 sculpturen en ornamenten is zonder chemisch onderzoek niet van hout te onderscheiden.The appearance of the panels, 8303947 · 4 / -3-1 sculptures and ornaments obtained according to the method described cannot be distinguished from wood without chemical research.

Het voordeel ten opzichte van oplijmen is vooral gelegen in de ongevoeligheid ten opzichte van temperatuur en relatief vochtgehalte van de lucht 5 en het niet optreden van lijmvoegen, scheuren en kromtrekken.The advantage over gluing lies mainly in the insensitivity to temperature and relative moisture content of the air 5 and the absence of glue joints, cracks and warping.
