The foamed sheet is inserted into the foam sheet, brought into contact with the mirror roll 3, and heated by a heating device 4 disposed near the outside thereof to soften or melt the foam sheet surface. The plastic foam sheet 1 is continuously laminated or embossed by being inserted therethrough and brought into contact with the emboss roll contacting surface of the emboss roll 5. In addition, code 2 in the figure
b is a drive roll.

た。 However, in this device, when the plastic foam sheet 1 comes into contact with the mirror roll 3, air is drawn between the plastic foam sheet 1 and the mirror roll 3. When this air is drawn in, an air pocket 6 is generated between the plastic foam sheet 1 and the mirror roll 3. When this air pocket 6 is generated, the plastic foam sheet 1 is distorted, and when the crest processing is applied, the foam sheet 7 is deformed into a wave shape, and the crests are deformed.

が最も良好に得られる。 In the figure, reference numeral 8 is a grooved mirror roll in which a large number of air vent grooves 9 are formed. As shown in FIG. 3, this air vent groove 9 consists of a horizontal groove 9a parallel to the mirror roll axis and a vertical groove 10 along the outer periphery of the mirror roll.
It is composed of a combination of b. The shape of the air vent groove 9 is not particularly limited, such as a V-shaped groove or a concave groove. The width of the air vent groove 9 is preferably 0.1 to 3.0 mm, preferably 0.1 to 0.5 mm. Groove depth is 0.1~
3.0 mm, preferably 0.1-0.5 mm is suitable. The groove spacing for both the horizontal grooves 9a and the vertical grooves 9b is preferably 1.0 to 500 mm, preferably 5 to 100 mm. When the air vent grooves 9 are set within this range, no trace of the air vent grooves 9 remains on the back surface of the plastic foam sheet 1, and the air venting effect of the air pockets 6 generated between the mirror roll 3 and the plastic foam sheet 1 is improved. best obtained.
なお、実施例では第３図に図示したように溝付
鏡面ロール８のエアー抜き溝９として、横溝９ａ
および縦溝９ｂが設けられている例を示したが、
これに限定されるものでなく傾溝としてもよい。 In addition, in the embodiment, as shown in FIG.
Although an example in which vertical grooves 9b and 9b are provided is shown,
The groove is not limited to this, but may be an inclined groove.

従つて変形のない積層シート、紋付発泡シートが
得られ、紋目にも変形が生じるおそれがない。 As explained above, in the air entrainment prevention device of the present invention, since the mirror roll is provided with air release grooves, it is possible to prevent air from forming between the plastic foam sheets.
Therefore, a laminated sheet and a foamed sheet with crests that do not deform can be obtained, and there is no possibility that the crests will be deformed.
