Abstract

A Lenticular stamping mechanism for liquid polymers with a controlled LED Ultra Violet light source for applying a metered amount of polymer to a substrate to force and cure it into a lenticular lens shape. Intended for use in or on top of existing (graphic) equipment to (locally) apply a so-called spot lens, a substrate for refinement and security.

Description

i

Lenticular stamping mechanism for liquid polymers with a controlled LED Ultra Violet light source for applying a metered amount of polymer to a substrate and forcing it into the shape of a lenticulaive lens to harden the polymer by means of a lenticular lens. from an Ultra Violet light source.

The invention relates to a stamp cylinder with counter pressure with a vertically movable stamp provided with a transparent cast silicone mold, placed in a cylinder with a sensor-controlled LED Ultra Violet light source which is connected to a metered injection head for liquid bars polymers with the aim of delivering a metered amount of polymer. to be applied to a substrate and forced into shape and hardened, {see appendix fig. 1A sketch of stamping cylinder fig.18 sketch cross-section of stamping cylinder)

The term outrigger cylinder here refers to the vertically movable outrigger mechanism in a cylinder-shaped housing

The term counter pressure refers to the limitation of the vertically movable stamp mechanism

The term vertically movable stamp mechanism refers to the movable stamp in a cylindrical sliding bearing containing a driven cylinder containing a driven stamp and sliding bearing [See appendix fig. 2}

The term Ultras Violet light source means an Ultra Violet lamp placed in the hollow space of the driven cylinder {see appendix fig. 3}

The term metered injection nozzle means an injection nozzle using existing and proven techniques, {not shown in the figures)

The aim of the invention is to place a crystal clear lenticuisire lens positioned on a coded printed substrate in existing and proven techniques in the graphics industry, {see appendix fig.4)

According to the git invention, this can be achieved by a measured amount of transparent

Polymer to be injected into the lower chamber of the driven cylinder by means of a supply, (see appendix fig.6)

The term lower chamber refers to the space that is created when the driven cylinder is in the limited lower position and the punch is in the limited upper position {fig. BA)

According to the invention, this injection can be achieved by providing the stamping cylinder with a round passage connected to the supply to the injection head {see appendix fig. 6B}

According to the invention, the formation of the lens can be achieved by placing the driven cylinder for injecting the polymer in the lower limited position so that the later injected polymer cannot flow away because it is retained by the walls of the driven cylinder. see appendix fig. 7}

According to the invention, this can be further achieved by applying a transparent silicone mold to the stamping cylinder (see appendix fig. 8A} with a center opening as an inlet for the polymer, see appendix fig. 88}

The term stamping cylinder refers to the transparent cylinder in the driven cylinder {see appendix fig, 8B)

According to the invention, this can be further achieved by moving the stamp stamp cylinder to the lowest limited position after injecting the polymer. The polymer is then forced into the shape of the mold.

According to the invention, this can be further achieved by exposing the polymer formed in the lower position of the driven cylinder and the lower position of the stamping cylinder with an ultraviolet light at the frequency that changes the properties of the polymer from liquid to solid form. changes due to hardening. {see appendix fig. 9)

According to the invention this is achieved by making the polymer inlet and driven cylinder of light-tight and UV-resistant material

According to the invention, this is also achieved by providing the inner wall of the driven cylinder with a coating that cannot adhere to the polymer. {see appendix 10A)

According to the invention, a lenticular lens impression is achieved when unlocking the lower boundary of the stamp and cylinder (see appendix fig. 108).

The stamping process of the invention is depicted in Fig. 11

The invention aims to be mounted in existing equipment which then makes it possible to print a lenticular lens on a coded printed substrate

The invention aims to use existing lenticular techniques to place one or more graphically printed codes or images under the polymer lens made, so that they cannot be copied with a copy machine, but can be read with a device, {see fig. 12)

The invention aims through the combination of uniquely printed codes, stamped with positioned lenticular lenses. adding an extra level of security to labels and packaging,
