SHEET MANUFACTURING APPARATUS AND MANUFACTURING METHOD

摘要

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<8> (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.
