Abstract

PURPOSE: To produce a sheet for industrial material with excellent tensile-strength and good piezolelectric property by pressurizing and rolling in stages themoplastic synthetic resin sheet with crystalline chain high molecule structure, using hot rollers and extension rollers.
CONSTITUTION: Thermoplastic synthetic resin sheet 20 with crystalline chain high molecule structure is heated and rolled by heating rollers 2, 2, a hot sheet material guide plate 4, rolling rollers 5, 5 receiving rollers 6, 6. Next, it is extended to a fixed ratio between receiving rollers 6, 6 and an extension roller 9, then rolling distortion being eliminated, it is rolled by the extension roller 9 and moved through guide rollers 10, 10 to be a pressurized and extended sheet 21. Next, side edges are cut by a trimming cutter 11 to finish the pressurization and rolling process. Then, it is again rolled by an extension roller 14 to make the extension amount as fixed and to be wound on a winding reel 17 with extension distortion sufficiently eliminated.
