Description

[Detailed Description of the Invention] The present invention relates to an embossing roll in which a plurality of ring rolls having different surfaces are fitted into a single core roll, and each ring roll is detachably attached to each other.

In more detail, a plurality of ring rolls each having a different type of surface such as an engraved surface, a smooth surface, or a mixed surface with engraved smooth surfaces, and whose inner diameters change linearly from the inner diameter of the inner hole to the outlet, are combined together. This invention relates to an embossing roll that can be attached to and removed from the tapered core roll of a book at any time to change the embossed pattern, especially the embossed pattern that appears in a band shape on the surface of the object to be embossed, for each band as necessary. .

Conventionally, embossing rolls have a fixed pattern engraved on the surface of a metal roll, and each pattern is unique, and each time a different pattern is required, a separate embossing roll must be manufactured. Ta.

Manufacturing a new emboss roll for each embossed pattern requires a lot of cost and is uneconomical.The cost increases the price of the embossed product (sheet product) and also increases the cost of engraving the emboss roll. There are problems in that manufacturing requires a great deal of effort and time.

The inventor of the present invention succeeded in developing a mechanism for replacing only the embossed surface of one roll, thereby solving problems such as slanted rolls.

In this invention, a plurality of ring rolls with different types of surfaces (different types of engravings) are prepared so that they can be fitted into a single roll outside the core (core roll) and connected to each other. If necessary, these ring rolls are combined into a core roll, connected and fixed, and a desired engraved pattern can be incorporated on the periphery of the core roll, or an embossing roll can be freely rearranged.

In other words, the embossing roll of the present invention can be used as a single embossing roll of a plurality of different types.

In the present invention, when incorporating an embossing roll using one core roll and multiple ring rolls, the core roll whose width matches the width when the required number of ring rolls are connected is selected and used. be.

By the way, when the ring roll is inserted and fixed into the core roll and is rotated, the change in the close contact between the core roll and the ring roll will cause dust on the surface of the roll and the stability of the ring roll (preventing dropping). This problem is important in the present invention.

In the present invention, the core roll has a taper, and the ring roll has an inner diameter that extends from the entrance of the inner hole, and the inner diameter is changed according to the taper of the core roll.
This improves the degree of adhesion between the core roll and the ring roll, as well as the stability of the ring roll (prevents slippage).

Various methods are possible for connecting the ring rolls incorporated in the core roll, but for example, the method of connecting the ring rolls with each other with a twist as shown in FIG. A method is adopted in which a provided protrusion is connected to a corresponding hole in an adjacent ring roll.

Furthermore, in order to completely prevent misalignment between the core roll and ring roll that may occur when the embossing roll of the present invention is rotated, grooves or protrusions are provided on the surface of the core roll in the width direction. It is also conceivable to provide a convex or concave line on the inner surface of the ring roll that engages with the concave or convex line.

There may be one or more uneven stripes.

Although metal is generally used as the material for the ring roll, it is not necessarily limited to metal, and in some cases, hard rubber, plastics, etc. can also be used.

Hereinafter, the present invention will be described in more detail with reference to the drawings.

FIG. 1 shows an example of a tapered core roll 1. This core roll 1 is inserted into the ring holes 9 of ring rolls a, b, and c as shown in FIG. 6 and a female screw 5 for connection and fixation.

In this way, the core roll 1 and ring rolls a and b are formed.

By combining the dissimilar surfaces 2, 3, . . . as illustrated in FIG. -- The embossing roll 10 having one is assembled.

In this case, the ring roll of FIG. 2C has a male thread, located at the end when assembled.

By passing the sheet 12 to be embossed between the embossing roll 10 and the back roll 11 assembled in this way, a different pattern surface 1 is formed as shown in FIG.
An embossed sheet 16 having 3, 14 is obtained.

Next, a new embossing roll with an engraved surface 15 is obtained by replacing ring roll b with ring roll d and rearranging it as ring roll atd.

FIG. 5 is a sectional view showing a state in which the tapered core roll 1 is assembled with each ring roll corresponding to the taper, and the embossing roll of the present invention is in close contact with the core roll.

Embossed pattern that appears on the surface of the embossed sheet by the embossing roll of the present invention: d1 Not only the embossed pattern that runs in the vertical direction of the sheet as shown in Fig. 4, but also the engraved pattern on the surface of each ring roll. Depending on how you like it, it can be horizontally, diagonally, island-like, or even all over.
