Metodo di applicazione di foglie in metallo prezioso su pelle e similpelle Campo della tecnica dell’invenzione. Method of applying leaves in precious metal on leather and imitation leather Field of the technique of the invention.

La presente invenzione riguarda un metodo di applicazione di foglie in metallo prezioso su pelle e similpelle. Il metodo à ̈ semplice da usare e non richiede attrezzature particolari. Inoltre, le foglie in metallo prezioso, sono protette dall’abrasione. The present invention relates to a method of applying precious metal leaves on leather and imitation leather. The method is simple to use and requires no special equipment. In addition, the precious metal leaves are protected from abrasion.

Stato dell’arte State of the art

Foglie di metalli preziosi in particolare d’oro sono state utilizzate fin dai tempi antichi per dorare cornici e mobili. Un antico metodo utilizzato per la doratura prevede una prima fase denominata imprimitura, consistente nella preparazione del fondo con colla di coniglio, una seconda fase denominata ammanitura, consistente nel passare a strati 350 gr. di gesso di Bologna in mezzo litro di colla di coniglio e nel levigare ogni strato con carta abrasiva, una terza fase in cui si passa il bolo diluito, una quarta fase in cui si stende la foglia d’oro sul bolo, un'ultima fase della doratura à ̈ la brunitura con pietra d'agata. Leaves of precious metals, particularly gold, have been used since ancient times to gild frames and furniture. An ancient method used for gilding involves a first phase called priming, consisting in the preparation of the base with rabbit glue, a second phase called ammanitura, consisting of passing 350 gr in layers. of Bologna gypsum in half a liter of rabbit glue and in smoothing each layer with sandpaper, a third phase in which the diluted bolus is passed, a fourth phase in which the gold leaf is spread over the bole, a last phase of gilding is the burnishing with agate stone.

Detto metodo non permette di applicare foglie d’oro o di altri metalli preziosi su supporti flessibili come tessuti, pelle e similpelle. This method does not allow to apply leaves of gold or other precious metals on flexible supports such as fabrics, leather and imitation leather.

Un metodo di applicazione di foglie in metallo prezioso su tessuto à ̈ descritto nella domanda di brevetto CS2009A000008. Il metodo à ̈ finalizzato all’applicazione di foglie in metallo prezioso su tessuto, esso non à ̈ applicabile alla pelle o alla similpelle in quanto in questi materiali non à ̈ presente una trama in cui una vernice può facilmente penetrare e creare una base di supporto per l’applicazione della foglia di metallo prezioso. A method of applying precious metal leaves on fabric is described in patent application CS2009A000008. The method is aimed at applying precious metal leaves on fabric, it is not applicable to leather or imitation leather as in these materials there is no texture in which a paint can easily penetrate and create a base of support for the application of the precious metal leaf.

La presente invenzione si propone lo scopo di superare gli svantaggi e le difficoltà presenti nei metodi proposti dallo stato dell’arte. The present invention aims to overcome the disadvantages and difficulties present in the methods proposed by the state of the art.

La presente invenzione si propone, invece, attraverso un particolare metodo di applicazione di foglie in metallo prezioso di realizzare disegni di qualsiasi tipo con contorni ben definiti, con una superficie liscia e omogenea e con una ottima resistenza superficiale. The present invention, on the other hand, proposes, by means of a particular method of applying precious metal leaves, to produce designs of any type with well-defined contours, with a smooth and homogeneous surface and with excellent surface resistance.

Lo scopo principale della presente invenzione à ̈ conseguito per mezzo di un metodo di applicazione di foglia in metallo prezioso su pelle e similpelle caratterizzato dal fatto che comprende le seguenti fasi: The main object of the present invention is achieved by means of a method of applying a precious metal leaf on leather and imitation leather characterized in that it comprises the following steps:

a) Dopo aver posizionato la pelle o la similpelle e avergli applicato una maschera, su detta pelle o similpelle si applica un collante con solvente e si lascia essiccare; a) After positioning the leather or imitation leather and applying a mask to it, an adhesive with solvent is applied to the leather or imitation leather and it is left to dry;

b) si prepara un impasto di copolimeri acrilici miscelati con una pasta al carbonio e si passa tre volte detto impasto sulla pelle o similpelle; c) ad essiccazione avvenuta si procede con l’applicazione di uno o più strati di vernice trasparente robusta del tipo flatting marino; d) in una fase successiva si procede con l’applicazione di uno strato di missione oleosa a dodici ore contenente resina naturale ed essenza di trementina; b) a mixture of acrylic copolymers mixed with a carbon paste is prepared and said mixture is passed three times on the leather or imitation leather; c) after drying, proceed with the application of one or more layers of robust transparent varnish of the marine flatting type; d) in a subsequent phase we proceed with the application of a layer of oily mission at twelve hours containing natural resin and essence of turpentine;

e) ad essiccazione avvenuta, si stende la foglia di metallo prezioso facendola aderire con una leggera pressione su detti strati e lasciando riposare per 24-48 ore; e) after drying, the precious metal leaf is spread, making it adhere with a slight pressure on said layers and letting it rest for 24-48 hours;

f) si protegge la superficie con una vernice acrilica trasparente, si lascia essiccare e si asporta la maschera. f) the surface is protected with a transparent acrylic varnish, it is left to dry and the mask is removed.

Altra caratteristica à ̈ dal fatto che la pelle o la similpelle si posizionano con un collante rimovibile lasciandolo essiccare per 16-24 ore. Another feature is the fact that the leather or imitation leather is positioned with a removable glue, leaving it to dry for 16-24 hours.

Altra caratteristica à ̈ dal fatto che i copolimeri acrilici hanno caratteristiche elastomeriche ad elevata impermeabilità. Another feature is the fact that the acrylic copolymers have elastomeric characteristics with high impermeability.

Altra caratteristica à ̈ dal fatto che l’impasto di copolimeri acrilici e pasta al carbonio, viene passato tre volte sul pellame. Another feature is the fact that the mixture of acrylic copolymers and carbon paste is passed three times over the leather.

Altre caratteristiche e vantaggi dell'invenzione appariranno chiari dalla descrizione di un modo di realizzazione dell’invenzione, qui appresso, dato a titolo d'esempio non limitativo. Other characteristics and advantages of the invention will become clear from the description of a way of carrying out the invention, hereinafter, given by way of non-limiting example.

Modo preferito di realizzazione dell’invenzione Preferred way of carrying out the invention

Il pellame si posiziona su una base con collante rimovibile e su di esso si applica una maschera del disegno da realizzare con l’applicazione di foglia in metallo prezioso, che nel caso particolare, ma non limitato a questo, à ̈ in oro. The leather is placed on a base with removable glue and on it a mask of the design is applied to be created with the application of a precious metal leaf, which in the particular case, but not limited to this, is in gold.

Per l’applicazione della foglia d’oro il processo prevede sei fasi: For the application of the gold leaf, the process involves six phases:

a) Sulla pelle si applica un collante con solvente in modo da penetrare nello stesso pellame dilatando i pori dello stesso pellame. Il collante si lascia essiccare per 16-24 ore. Man mano che il pellame si essicca diventa appiccicoso. a) A solvent-based glue is applied to the leather in order to penetrate into the same leather by dilating the pores of the same leather. The adhesive is allowed to dry for 16-24 hours. As the leather dries it becomes sticky.

b) Successivamente si prepara un impasto di copolimeri acrilici con caratteristiche elastomeriche ad elevata impermeabilità miscelati con una pasta al carbonio. Questo impasto di copolimeri acrilici e pasta al carbonio, viene passato tre volte sul pellame. c) Ad essiccazione avvenuta si procede con l’applicazione di uno o più strati di vernice trasparente robusta del tipo flatting marino con elevata resistenza e brillantezza. b) Subsequently, a mixture of acrylic copolymers with highly impermeable elastomeric characteristics mixed with a carbon paste is prepared. This mixture of acrylic copolymers and carbon paste is passed three times on the leather. c) After drying, proceed with the application of one or more layers of robust transparent varnish of the marine flatting type with high resistance and brilliance.

d) In una fase successiva si procede con l’applicazione di uno strato di missione oleosa a dodici ore contenente resina naturale ed essenza di trementina. d) In a subsequent phase we proceed with the application of a layer of oily mission at twelve hours containing natural resin and essence of turpentine.

e) Ad essiccazione avvenuta, gli strati sono pronti a ricevere la foglia d’oro che, con una leggera pressione, si fa aderire su detti strati. e) After drying, the layers are ready to receive the gold leaf which, with a slight pressure, is made to adhere on said layers.

Si lascia riposare il tutto per 24-48 ore It is left to rest for 24-48 hours

f) In un’ultima fase si procede alla protezione superficiale con una vernice acrilica trasparente. Si lascia essiccare e si asporta la maschera. f) In a last phase, the surface is protected with a transparent acrylic paint. It is left to dry and the mask is removed.
