    • A fused sheet-like body extruded onto a moving cooling body is properly cooled by giving an appropriate amount of charge to the full width of the fused sheet-like body and bringing the fused sheet-like body into close contact with the moving cooling body. A sheet manufacturing apparatus comprises an extruder (3) for extruding a thermoplastic resin having a fusion resistivity of 0.3x10 (ohm.cm) or more, a moving cooling body (5), and a tape-like electrode (10). The sheet manufacturing apparatus further comprises a central portion support member (24) supporting an electrode central portion (12) linearly stretched, an ear portion support member (26) supporting an electrode ear portion (13) displaced toward the downstream side in the direction of the sheet transfer, a pair of displacement adjusting mechanisms for adjusting the displacement X of the electrode ear portion (13), and a travel drive mechanism for driving the tape-like electrode (10) to travel along the width direction alpha of the fused sheet-like body (4a). A method for manufacturing such a sheet is also disclosed.
    • 通过对熔融的片状体的全部宽度给予适当的电荷并使熔融的片状体与移动的冷却体紧密接触,适当地冷却挤出到移动的冷却体上的熔融片状体。 片材制造装置包括挤出机(3),用于挤出具有0.3×10 8(ohm·cm)以上的熔融电阻率的热塑性树脂,移动冷却体(5)和带状电极(10) 。 片材制造设备还包括支撑线性拉伸的电极中心部分(12)的中心部分支撑部件(24),支撑电极耳部(13)的耳部支撑部件(26),该电极耳部部分 片材传送,用于调节电极耳部(13)的位移X的一对位移调节机构和用于驱动带状电极(10)沿着熔融片的宽度方向α行进的行进驱动机构 (4a)。 还公开了制造这种片材的方法。
