。(Prior art and its problems) In conventional plastic sheet extrusion molding, the method for forming embossed patterns on both sides of a molded product is to move from the mouthpiece G of the extruder F in the direction of the arrow, as shown in the side view in Figure 2. Using three metal rolls, the extruded molten resin sheet D is first passed under pressure between a lower roll A and a middle roll B whose surface is embossed to form a pattern on one side of the molten resin sheet D. Sheet E is then passed under pressure between the middle roll B and an upper roll C whose surface is embossed in the same manner as above to form a pattern on the other side of the molten resin sheet D to form a double-sided embossed pattern. A common processing method is to obtain .

う問題があった。However, in the above conventional method, the molten resin sheet D is cooled while reaching the upper roll C, and the viscosity of the surface of the sheet 59 increases and becomes close to a solidified state, resulting in partial transfer failure or overall The embossed pattern becomes shallower,
There was a problem in that the embossed pattern on the roll surface was insufficiently transferred to the sheet surface, such as the front embossment and the back embossment becoming uneven.

加工方法である。(Means for Solving the Problems) The present invention is a double-sided embossing method for solving the above-mentioned problems, and its gist is to provide a metal roll whose surface is embossed and a metal roll which is also embossed. This double-sided embossing method is characterized by simultaneously applying embossing to both sides of the resin sheet by passing a melt-extruded resin sheet while being compressed between a rubber roll made of rubber.
以下本発明を図面により具体的に説明する。The present invention will be specifically explained below with reference to the drawings.

ート6が得られる。As shown in a side view of an embodiment of the present invention in FIG. 1, the present invention is characterized in that a molten resin sheet 4 extruded from a mouthpiece 8 of an extruder 7 in the direction of the arrow is transferred to a rubber roll ( A metal roll (hereinafter referred to as "Rule 20") with the same embossed surface as 1 (hereinafter referred to as "Rule 20")
The embossed pattern is simultaneously transferred to both sides of the molten resin sheet 4 at the emboss transfer section 5 while being passed under pressure between the molten resin sheet 4 and the molten resin sheet 4. ) 3 while cooling in the direction of the arrow to obtain a molded sheet 6 with clear embossed patterns transferred to both sides.

やすい。The 10th rule 1 is preferably a rubber roll with a shore hardness of Hs 60 to 70. If it is soft below Hs 60, it is difficult to obtain the thickness accuracy of the molten resin sheet 4, and if it is hard and hard above Hs 70, it tends to result in unclear transfer. The temperature condition is the 10th
- Rule 1 is 30-60°C, and 20th - Rule 2 is 100°C.
~180° C. is preferable; below the above ranges, the emboss transfer tends to be insufficient, and above the above ranges, the molten resin sheet 4 tends to stick to the roll surface, causing trouble.

。(Function of the invention) In the present invention, a rubber roll having the shore hardness and temperature conditions as described above is used, and the surface of the 10th rule 1 is embossed, and the surface of the roll 1 is embossed. When the molten resin sheet 4 is pressed under the above-mentioned linear pressure between the metal No. 20-ru 2 under the temperature conditions, the No. 10-ru 1 causes concave deformation at the embossed transfer portion shown in FIG.
Since both surfaces of the molten resin sheet 4 are in surface pressure contact with both rolls 1.2, the temperature of the molten resin sheet 4 itself immediately after being discharged from the nozzle 8 is high, and while the melt viscosity is low, the roll 1.
The embossed pattern can be reliably and clearly transferred to both sides of the molten resin sheet 4 by applying the embossed pattern between the two.

When the embossed patterns of both the 10th and 20th rules are transferred under pressure between the 20th and 20th rules, the embossed patterns of both the 10th and 20th rules are clearly and evenly transferred to both sides of the sheet to obtain a molded sheet with beautiful appearance quality. was completed.
