2. Description of the Related Art Conventionally, a raw material before cutting a foil thread for a fabric or the like by using a cutting machine such as a slitter is provided with an embossed pattern on one or both sides thereof to reduce uneven gloss due to irregular reflection of light. What has appeared is well known.

[0003] Such a raw material is, for example, a material obtained by sticking a synthetic resin film having a metal vapor-deposited layer of aluminum or the like formed on one surface thereof, or a metal vapor-deposited layer of aluminum or the like formed on both surfaces, for example, using Japanese paper or the like as a core material. A material having a synthetic resin film adhered thereto or the like is carried out. Such a raw material is formed between an embossing roll which is appropriately engraved in a pattern and a pressing roll which is called a paper roll and is pressed against the embossing roll. And the embossed raw material that has passed through is wound up on a roll. However, according to the conventional embossing method, embossing can be performed on only one side of the raw material, and embossing is performed on both sides of the raw material.

Next, an example of an embossing method of a raw material according to the present invention will be described in detail.

FIG. 1 is a flow sheet for carrying out the method of embossing a raw material according to the present invention, and 1 is an embossing roll on which a satin pattern or other appropriate pattern is engraved on the surface. A desired heater device is interposed inside 1. Reference numerals 2 and 3 denote pressing rolls called paper rolls disposed on the upper side and the lower side of the embossing roll 1, respectively. The pressing rolls 2 and 3 are pressed against the embossing roll 1, and And the parallel axis. A is a raw material before embossing, and the raw material A is a material in which a synthetic resin film having a metal vapor-deposited layer of aluminum or the like provided on one surface thereof is adhered to a core material of Japanese paper or the like, or What adhere | attached respectively the synthetic resin film which formed the metal evaporation layer of aluminum etc. on both surfaces is used. 5 is a guide roll provided with a cooling portion, and 6 is a cooling device for cooling the raw material A embossed on both sides.
It is a roll.

The raw material A before embossing is unwound from a roll and embossed, and the embossed raw material B is wound up into a roll. The raw material A first passes through an appropriate guide roll 4, and is then transferred to an embossing roll apparatus including a set of three contact rolls including an upper pressing roll 2, a center embossing roll 1, and a lower pressing roll 3. The raw material A is guided between the embossing roll 1 and the lower pressing roll 3, and an embossed pattern is continuously engraved on one surface of the raw material A with the pressing action.

The raw material A having this embossed surface on one side
Is further guided through a guide roll 5 having a cooling portion that can be appropriately cooled as needed, between the embossing roll 1 and the upper pressing roll 2 in a set of three embossing rolls, and the pressing action is performed. Along with the front side of the target web A

It will be engraved more continuously. However, the material to be embossed is preferably a material in which a synthetic resin film obtained by vacuum-depositing metal or the like is adhered to one surface of a material such as Japanese paper as a core material. By embossing at a high temperature of 150 ° C. to 150 ° C., irregularities due to the emboss are deeply engraved on the material.

More specifically, the first method of embossing both the front and back surfaces of the raw material A will be described in detail. The raw material A is wound up as an embossed raw material B. At this time, the raw material A is unwound from the roll, passes through an appropriate guide roll 4 and is transferred between the embossing roll 1 and the lower pressing roll 3 in the embossing roll device. As a result of the pressing action, an embossed concavo-convex pattern is continuously engraved on one side of the raw material A, and then, as shown in FIG. It is guided to two U-shaped rolls 7 and 8 having an inclination angle of 45 degrees in the traveling direction with respect to the core, and the one roll 7
The front and back of the original anti-A to reverse me. That is, for example, the raw material A that has passed through the embossing roll 1 and the lower pressing roll 3 is turned upside down from the lower side of one of the C-shaped rolls 7 and then turned upside down from the lower side of the other roll 8. The original material A is the one of the two rolls 7 and 8 in a U-shape.
7, the front and back are reversed. Thus, the original web A reversed by the other roll 8 is turned over.
After being returned to the transition state, it is guided between the embossing roll 1 and the upper pressing roll 2, and the other surface, which is the unembossed surface of the raw material A, is pressed against the embossing roll 1 surface. Thus, the other surface is also embossed. Next, through a cooling roll 6 having a cooling device as appropriate, a processed material B having both the front and back surfaces of the material A embossed is produced. In such front and back embossing, the width of the embossing roll 1 is at least twice the width of the raw material A, and in some cases, the width of the raw material A is less than half the width of the embossing roll 1, and the raw material A is One side of the embossing roll 1 is embossed to be eccentric to the other end, and then the web A is embossed.
Once you have turned it upside down,
Thus, the raw material A is eccentric to the other end of the embossing roll 1 and the other surface is embossed. The raw material A to be embossed on both sides is preferably a material in which a synthetic resin film in which a metal vapor-deposited layer of aluminum or the like is formed on both sides of a core material is appropriately adhered.

Next, the second method of embossing the front and back surfaces of the raw material A will be described in detail. In the same manner as described in the first method described above, the advancing in different inclination directions having a 45 ° inclination angle is performed. Lead to two rolls 7 , 8
Then, the front and back of the web A are reversed by the one roll 7 , and then the transfer of the original web A is performed by the other roll 8.
After returning to the state, it is further guided to two parallel rolls 9 and 10 having an inclination angle of 45 degrees in the traveling direction.

Therefore, the front and back are reversed, and the other roll 8
The original raw material A is returned to the transition state. This web A is further inverted from the lower side of one of the parallel rolls 9 to the upper side and from the upper side of the other parallel roll 10 to the lower side, whereby the original web A is turned upside down by the one roll 9. to state
Be placed . Then, the reversed web A is turned into the other row.
After being returned to the original transfer state of the raw material A by the roll 10, it is guided between the embossing roll 1 and the upper pressing roll 2, and the other surface, which is the unembossed surface of the raw material A, is
It is pressed against the surface, the other surface is embossed by the pressing action, and the processed raw material B having both front and back surfaces embossed is similarly produced through the cooling roll 6. According to the second embossing method, embossing can be performed at a normal position without having to transfer the raw material to one side of the embossing roll 1 in advance unlike the first embossing method.

[0014]

According to the method for embossing a raw material according to the present invention, a pair of embossing rolls, each of which has two embossing rolls 2 and 3 pressed against an upper side and a lower side of the embossing roll 1, respectively. Since the raw material is subjected to two embossing processes at the same time using these rolls without using a roll device, when embossing both surfaces of the raw material A, both processes are performed in one process.
Surface embossing can be done and produced by the same lot
Therefore, the uneven pattern can be made uniform on both sides , the unevenness of the embossed luster of the product can be eliminated, and unlike the conventional method, the processing time can be remarkably reduced, and the economic effect becomes enormous.

Further, since the three rolls constitute one set, the embossing roll 1 can be pressed uniformly by the two upper and lower pressing rolls 2 and 3, and the pressing force against the raw material can be balanced. A reliable processed raw material B that does not exhibit unevenness and gloss unevenness can be obtained. Furthermore, since the second embossing can be performed by using the preheating, the thermal efficiency is excellent, and there is an effect that a deep uneven pattern can be formed.
