SHEET MANUFACTURING APPARATUS AND MANUFACTURING METHOD

摘要

[Summary] [Problem] Proper cooling of a molten sheet product by bringing the sheet into close contact with a movable cooling member, by properly charging over the whole width of the molten sheet product extruded on the movable cooling member. [Solving Means] A sheet production apparatus comprising an extruder 3 to extrude a thermoplastic resin having a melt specific resistance value of not less than 0.3 × 10 8 (©·cm), a movable cooling member 5, and a tape electrode 10, which has a constitution including a center support member 24 to support the center 12 of the electrode in a linearly stretch state, an ear portion supporting member 26 to support an ear portion of the electrode 13 shifted to the downstream side in the sheet transport direction, a pair of displacement amount adjust mechanisms to adjust a displacement amount X of the above-mentioned ear portion of the electrode 13, and a travel drive mechanism to run the tape electrode 10 along the width direction ± of the molten sheet product 4a, and a production method thereof.
