In the manufacturing apparatus as described above, the synthetic resin 14 in the storage tank 28 is filled into the intaglio pattern 12 of the mold 11 via the application roll 29, and then A part of the outer surface of the synthetic resin 14 filled in the intaglio pattern 12 is scraped off into a mortar shape by the doctor plate 15, and the synthetic resin sheet 4 supplied toward the mold 11 is The storage tank 21 is provided on the lower surface side of the tank via the coating roll 19.
The liquid synthetic resin 20 loaded on the mold 11 is applied, and the side of the synthetic resin sheet 4 on which the liquid synthetic resin 20 is applied is guided to the outer surface of the mold 11 by the pasting roll 30.

At this time, the mold 11 is under a heated state, and the synthetic resin 14 filled in the intaglio pattern 12 of the mold 11 and the liquid synthetic resin 20 of the synthetic resin sheet 4 are joined, The liquid synthetic resin 20
is filled into the recesses on the outer surface of the synthetic resin 14 scraped by the doctor plate 15, and at the same time, the sheet 4 and the synthetic resin 14 in the intaglio pattern 12 of the mold 11 are bonded together, Intermediate product B
is manufactured.

As shown in FIG. 15, the intermediate product B has the liquid synthetic resin 20 filled inside the concave surface 2a formed in the patterned portion 2 of the sheet body 1, and the concave surface 2a side of the patterned portion 2. The synthetic resin sheet 4 is bonded together.

Next, the intermediate product B molded by the mold 11 is peeled off by the peeling roll 31 when the mold 11 is in a cooling state, and then the intermediate product B is peeled off by the peeling roll 31 and then by the intermediate roll 34 and the pressing roll 44. is guided and supplied to the heating cylinder 32 side via
At this time, the intermediate product B in the cylinder 32
The backing sheet 8 is coated with the liquid synthetic resin 35 in the storage tank 36 by the coating roll 37 on the outer surface side of the sheet body 1, that is, on the side opposite to the synthetic resin sheet 4 of the patterned portion 2 of the sheet body 1. It is supplied via a guide roll 45.

Thus, the intermediate product B and the backing sheet 8 guided and supplied onto the heating cylinder 32 are moved by the heating cylinder 32 and the press roll 44.
The backing sheet 8 is integrally adhered to the opposite side of the patterned portion 2 of the intermediate product B from the synthetic resin sheet 4, and at this time, the synthetic resin sheet 4 is pressed so as to bite into each patterned portion 2. The outer surface of the synthetic resin sheet 4 is made uneven in correspondence with the patterned portion 2, and at the same time, the liquid synthetic resin 35 provided on the backing sheet 8 is cured to become the colored layer 9. Thereafter, it is peeled off from the cylinder 32 side via the peeling roll 40, and is wound from the cylinder 32 onto the winding roll 41 as a synthetic resin pattern A.

As described above, the synthetic resin patterned area A shown in FIG. Since the mortar-shaped concave surface 2a provided on the outer surface of each patterned portion 2 is filled with blue synthetic resin 3, the deep blue color appears in the deep part of the concave surface 2a, and gradually becomes darker as the depth of the concave surface 2a becomes shallower. A bright blue color tinged with green is continuously exposed, and the depth change of the concave surface 2a in the pattern portion 2 is continuously exposed to the outside through the synthetic resin sheet 4 in a blur-like manner. In the synthetic resin patterned area A, a light blue colored layer 9 is interposed between the synthetic resin sheet 4 and the backing sheet 8 and between each of the pattern parts 2, and the colored layer 6 is interposed between the synthetic resin sheet 4 and the backing sheet 8. 4
Because it is exposed to the outside, a patterned area that looks like a glassy inlay pattern is obtained on both the front and back sides.

(Effects of the Invention) As explained above, in the present invention, it is possible to continuously change the color tone and brightness of the pattern portion 2 provided on the sheet main body 1, and to make the depth change of the pattern portion 2 externally visible. As a result, it is possible to easily obtain a patterned area made of synthetic resin that has a rich natural feel and three-dimensional effect.
