This device (1A) for producing a thermoplastic resin sheet forms a thermoplastic resin sheet (30A) by extruding melted thermoplastic resin from a die (10A), guiding the thermoplastic resin between a metallic belt (15A) and a third cooling roller (13A), and thereafter cooling and detaching the thermoplastic resin from the metallic belt (15A) while conveying the thermoplastic resin using the metallic belt (15A). Furthermore, the device (1A) is provided with: a warpage-correcting driving roller (18A) for correcting the warpage of the thermoplastic resin sheet (30A); a driving pinch roller (21A); a first load detector (171A); and a second load detector (201A). On the basis of the loads detected by the first load detector (171A) and the second load detector (201A), the sheet tension between the metallic belt (15A) and the driving pinch roller (21A) is controlled to within a predesignated range. |
