1 - Desbobinar a fita de polipropileno ou poliéster, metalizado 3-4;1 - Unwind the polypropylene or polyester tape, metallized 3-4;
2 - Aplicação da camada de silicone aditivado para marcação a laser 5 na face do filme metalizado 3-4 oposta à face metalizada 3 que receberá o adesivo sensível a pressão (PSA) preto ou o chapado de tinta preta; 2 - Application of the layer of silicone additive for laser marking 5 on the side of the metallized film 3-4 opposite the metallized side 3 that will receive the black pressure-sensitive adhesive (PSA) or the black ink coating;
3 - Aplicação da camada de adesivo sensível a pressão (PSA) preto 2 ou chapado de tinta preta 2’ na face metalizada 3, oposta à que contém a camada de silicone aditivado para marcação a laser 5, obtendo assim a fita autoadesiva para marcação de dados variáveis por raio laser 1 ; e 4 - Rebobinagem da fita autoadesiva para marcação de dados variáveis por raio laser 1 acabada feita no rebobinador extremo oposto 102, formando uma bobina de fita autoadesiva para marcação de dados variáveis à laser 1 na qual a camada de adesivo preto de uma dada espira fica colada de modo a poder ser descolada na camada de silicone aditivado para marcação a laser da espira imediatamente seguinte e sobre a camada de silicone de dita dada espira fica colada de modo a poder ser descolada a camada de adesivo de uma espira imediatamente anterior. 3 - Application of the layer of black pressure-sensitive adhesive (PSA) 2 or black paint 2' on the metallized face 3, opposite to that containing the layer of silicone additive for laser marking 5, thus obtaining the self-adhesive tape for marking variable data by laser beam 1; It is 4 - Rewinding of the self-adhesive tape for marking variable data by laser 1 finished on the opposite end rewinder 102, forming a coil of self-adhesive tape for marking variable data by laser 1 to which the black adhesive layer of a given turn is glued so that it can be peeled off on the silicone layer added for laser marking of the immediately following turn and on the silicone layer of said turn, the adhesive layer of an immediately previous turn is glued so that it can be peeled off.
[026] A metalização pode ser constituída pelo uso de um filme já metalizado ou metalização “feita em máquina” quando então o equipamento e processo são providos de dispositivo e etapa de processo adicionais específicos para aplicação da metalização. [026] Metallization can be constituted by the use of an already metallized film or “machine-made” metallization when the equipment and process are provided with an additional specific device and process step for applying the metallization.
[027] No caso do uso de chapado de tinta preta tricromia 2’, o equipamento e processo preveem dispositivo e etapa de processo adicionais específicos para aplicação de camada de adesivo transparente 6 sobre o chapado de tinta preta 2’. [027] In the case of using a trichromatic black paint coating 2', the equipment and process provide for an additional specific device and process step for applying a layer of transparent adhesive 6 on the black paint coating 2'.
[028] Em uma possibilidade, a fita autoadesiva para marcação de dados variáveis à laser 1 é marcada e aplicada na superfície de uma embalagem (caixa) 200 (fig. 4) através de equipamento etiquetador que provê: o avanço da fita; a marcação a laser; o corte; e a colagem dela na superfície receptora. [028] In one possibility, the self-adhesive tape for marking variable data by laser 1 is marked and applied to the surface of a package (box) 200 (fig. 4) through labeling equipment that provides: the advancement of the tape; laser marking; the cut; and gluing it to the receiving surface.
[029] A aplicação das etiquetas pode ser feita conforme previsto na patente BR 20 2015 031036-1 do mesmo Requerente. [029] The application of the labels can be done as provided for in patent BR 20 2015 031036-1 of the same Applicant.
[030] Dentro da construção básica, acima descrita, a fita autoadesiva para marcação de dados variáveis por raio laser 1 , objeto da presente patente, pode apresentar modificações relativas a materiais, dimensões, detalhes construtivos e/ou de configuração funcional e/ou ornamental, sem que fuja do âmbito da proteção solicitada. [030] Within the basic construction, described above, the self-adhesive tape for marking variable data by laser beam 1, object of this patent, may present modifications relating to materials, dimensions, construction details and/or functional and/or ornamental configuration, without leaving the scope of the requested protection.
