DETAILED DESCRIPTION OF THE ACCOMPANYING DRAWINGS:
According to this invention, there is provided a magnetic embossing machine.

Figures 1 and 2 illustrate an embodiment of the templates of the magnetic embossing machine as referred by reference numeral 10. Figure 3 illustrates an embodiment of the templates along with the dies placed, therein.

In accordance with an embodiment of this invention, there is provided an operative top metallic plate (12) and an operative bottom metallic plate (14). The operative top metallic plate is configured to sit on top of the operative bottom metallic plate. A sheet to be embossed is placed between these two plates whenever it is to be embossed. In at least an embodiment, the operative top metallic plate and the operative bottom metallic plate are hinged across one edge in order to form a book type template to receive the sheet, in the spaced apart distance between the plates, on to which embossing is to be done. These plates lay out the canvas or platform for locating dies (11). In at least an embodiment, the hinge is configured to provide movement for vertical and / or angular displacement.

The internal sides of each of the operative top metallic plates and the operative bottom metallic plates is a die mounting surface so that it can receive dies which are placed on to it. These surfaces are metallic in nature.

Reference numeral 12a refers to operative inner surface of operative top metallic plates.
Reference numeral 14a refers to operative inner surface of operative bottom metallic plates.

Reference numeral 16 refers to hinge which connects operative top metallic plate to operative bottom metallic plate.

In accordance with another embodiment of this invention, there is provided a die set comprising an operative male die and a corresponding female die. The male die comprises a protruding character that is to be embossed while a female die comprises a complementary slot of the character to receive the protruding character of the male die. This die set’s operative outer surfaces are magnetic in nature in order to enable it to stick to the operative top metallic plate and the operative bottom metallic plate. The operative male die and the corresponding female die are two separate dies between which a sheet to be embossed is placed.

It is to be noted that operative external surfaces of dies are magnetic in nature. These external surfaces are the surfaces on which the templates exert pressure. This specific configuration of the templates being metallic and the dies being magnetic ensures a relatively more stable operation, in that, the dies do not move from their set location once placed on the templates when the templates move to exert pressure on to the dies and the sheet therebetween. Also, this configuration is relatively inexpensive.

A plurality of such male dies and corresponding female dies can be placed across the operative bottom metallic plate in a fashion according to which embossing on the sheet is to be achieved.

First, the female dies in order and fashion are placed on the operative bottom magnetic die. Corresponding male dies are placed on top of it. The operative top metallic plate is brought down on to these located dies. The male dies get magnetically stuck to the operative top metallic plate while the female dies are already magnetically stuck to the operative bottom metallic plate. In a further action, the operative top metallic plate is pulled away, thereby pulling away the magnetically stuck male dies. This forms the setup and orientation. A sheet that is to be embossed is then placed between the two plates on to the female dies. The operative top metallic plate is then brought down with application of substantial pressure so that the male dies leave an embossed pattern on to the sheet. This entire series of actions comprises a single embossing action.

It is to be noted that the arrangement of male dies and female dies with respect to their location of operative top metallic plate and operative bottom metallic plate can be reversed.

The machine of this invention further comprises a foil mounting mechanism to provide a foil so that the embossed portions on the sheet metal can be foil stamped. The foil mounting mechanism may be located on the operative top of the machine so as to dispense foil onto the sheet when it is embossed.

In at least an embodiment, a pressure mounting mechanism is configured for application of pressure on to the operative top metallic plate such that it clamps down on the operative bottom metallic plate with the die sets loaded there between and with the sheet located between the male dies and the female dies.

In at least one embodiment, a naturally decompressed resilient mechanism is provided to interface the operative top plate to the operative bottom plate. This decompressed resilient mechanism, which is advantageously located, ensures that while upon actuation of force, the operative top plate clasps onto the operative bottom plate, with the sheet in between, and with the dies located on respective plates, thereby ensuring embossing, that upon releasing the force, the operative top plate spaces itself apart from the operative bottom plate.

In at least an embodiment, the magnetic embossing machine may be a hydraulically actuated machine, in that a hydraulic mechanism is advantageously employed in order to operate the exertion of force from the operative top plate to the operative bottom plate.

In at least an embodiment, the magnetic embossing machine may be a pneumatically actuated machine, in that a pneumatic mechanism is advantageously employed in order to operate the exertion of force from the operative top plate to the operative bottom plate.

In at least an embodiment, the magnetic embossing machine may be an electrically actuated machine, in that an electrical mechanism is advantageously employed in order to operate the exertion of force from the operative top plate to the operative bottom plate.

In at least an embodiment, the magnetic embossing machine may be a mechanically actuated machine, in that a mechanical mechanism is advantageously employed in order to operate the exertion of force from the operative top plate to the operative bottom plate.

Figure 5 illustrates another side view of the magnetic embossing (100).

Figure 6 illustrates an exploded view of the magnetic embossing (100).

Figure 7 illustrates a top view of the magnetic embossing (100).

In at least an embodiment, the machine comprises a foldable base plate (32). In at least another embodiment, the machine comprises a fixed top plate (36) which is in a spaced apart position from the foldable base plate (32). The top fixed plate provides a downward reactive force when the operative top metallic plate and the operative bottom metallic plate, with dies located therebetween, are exerted against it. In at least yet another embodiment, the machine comprises a bottom moving plate (34) located between the foldable base plate (32) and the fixed top plate (36). Typically, the operative bottom metallic plate (14) the bottom moving plate (34) rests against the bottom moving plate (34). In its initial configuration, the bottom moving plate (34) is spaced apart from the fixed top plate (36). The entire mechanism which comprises the operative top metallic plate (12), the operative bottom metallic plate (14), and the dies are located in the spaced apart region of the bottom moving plate (34) and the top fixed plate (36). The bottom moving plate (34), preferably, is hydraulically actuated. The hydraulic mechanism (40 40ba) is show wherein reference numeral 40a refers to a hydraulic pump and reference numeral 40b refers to a hydraulic cylinder. In a preferred embodiment, owing to this configuration of the bottom plate being moving and the top plate being fixed, a single acting cylinder is provided, thereby providing reduction in inventory and costs of the machine. However, in another embodiment, there may be a double acting cylinder configuration wherein the top plate is moving and the bottom plate is fixed. In either scenario, there needs to be force exerted on the male and female dies located between the operative top metallic plate (12) and the operative bottom metallic plate (14). For all these plates, alignment may or may not be important as long as forces exerted or forces received are synchronous and uniformly distributed.

Figure 8 illustrates a magnetic template along with force plate.

Figure 9 illustrates a hydraulic mechanism for the magnetic embossing machine of this invention.

The TECHNICAL ADVANCEMENT of this invention lies in providing a magnetic embossing machine which is configured in a manner such that it provides free orientation, size, and layout of characters. In other words, the magnetic dies and the metallic plates templates interface with each other in order to achieve a plurality of sizes along with multiplicity of orientations for embossing on a plate, in a single embossing action.
