Description
【発明の詳細な説明】
本発明は、熱可塑性樹脂、殊に高流動性熱可塑性樹脂シ
−トの製造法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing thermoplastic resins, particularly highly fluid thermoplastic resin sheets.

'', and is produced by introducing it into the gap between the holes and taking it out while cooling.

ときエアー噛み等の不良を発生することが多かった。本
発明の目的は、上記のドローダウンを防止し、高流動性
の熱可塑性樹脂の押出しを可能とすることにある。However, when the thermoplastic resin has high fluidity, the extruded sheet 2 has a large drawdown between the T-die and the cooling rolls 3, 3', 3'', and when it is guided to the gap between the cooling rolls 3, 3', 3''. Defects such as air trapping often occurred. An object of the present invention is to prevent the above-mentioned drawdown and to enable extrusion of a highly fluid thermoplastic resin.
上記の目的を達成するため、本発明は第２図に示すよう

３′，３″の間に張設することにより、押出しシート２

間隙に導入するものである。In order to achieve the above object, the present invention involves wrapping an endless belt 4 around cooling rolls 3, 3', and 3'' arranged above and below, as shown in FIG.
By stretching between 3' and 3'', the extruded sheet 2
is carried by an endless belt 4 and introduced into the gap between cooling rolls 3, 3', and 3''.
５，５′，５″は無端ベルト４の張設ロールである。5, 5', 5'' are tension rolls of the endless belt 4.
上記のように構成することにより、高流動性熱可塑性樹
脂の場合にも押出しシートはドローダウンすることなく
冷却ロール３，３′，３″に導入される。With the above configuration, even in the case of a highly fluid thermoplastic resin, the extruded sheet can be introduced into the cooling rolls 3, 3', 3'' without drawdown.
尚、無端ベルト４は必ずしも冷却ロール３，３′，３″

It is not necessary to stretch the gap in a meandering manner, and the gap may be stretched between the T-die 1 and the cooling roll 3 at least over only the lowest cooling roll 3. By the method shown in FIG. 2, an extruded polypropylene sheet having an MI of 5 and 10 plates was manufactured using nylon cloth for the endless belt.

なるものである。As a result, it is possible to produce an extruded sheet with a thickness of 1 skin to IQ mosquito. As described above, according to the present invention, the extruded sheet from the T-die can be smoothly guided to the cooling roll without being drawn down, and in addition, since the extruded sheet is drawn down conventionally, the position adjustment range of the cooling roll can be adjusted. However, in the present invention, it can be freely adjusted and extruded sheets can be manufactured in the best condition. Furthermore, the endless belt can be used for embossing, etc. by selecting appropriate materials, and its industrial value is extremely great.
