摘要： According to the present invention, it is possible to easily manufacture a molded plate of a desired size by laminating an unnecessary, inexpensive resin not used as a product in the width direction of a molded plate and simply separating the unnecessary resin after forming the molded plate. Consequently, it is possible to skip a step of cutting the molded plate in the machine direction thereof. Further, it is also possible to skip a polishing step since the cut surfaces of the molded plate in the machine direction thereof can be smoothed. Still further, by arranging a plurality of resins for disposal, it is possible to effectively use the resins when yielding multiple molded plates from one resin sheet.
摘要翻译：根据本发明，可以通过在成型板的宽度方向上层叠不用作产品的不必要的廉价树脂，并且在形成模制板之后简单地分离不需要的树脂，容易地制造所需尺寸的模制板。因此，可以跳过在其成型方向上切割模制板的步骤。此外，由于模塑板在其加工方向上的切割面可以平滑化，所以也可以跳过抛光步骤。此外，通过配置多个待处理树脂，可以在从一个树脂片制造多个模制板时有效地使用树脂。

摘要： A method of producing an embossed sheet includes the steps of allowing a flexible strip-shaped sheet to continuously travel, forming a coating layer by coating the surface of the sheet with a radiation curable resin, transferring a pattern of concavities and convexities on the surface of the emboss roller to the coating layer by winding the sheet around the rotating emboss roller, curing the coating layer by irradiating the sheet which is wound around the roller with radiation, releasing the sheet from the emboss roller, laminating a protective film on one or both sides of the continuously traveling sheet after releasing, and taking up the continuously traveling sheet after lamination in the form of a roll. According to the method, a high quality, defect-free embossed sheet having a fine regular pattern of concavities and convexities on the surface can be produced at high line speed with high productivity.

摘要： This invention provides an indented sheet manufacturing method and apparatus which, by virtue of the use of CO2 gas as a gas accompanying a sheet-form body when the sheet-form body is caused to contact an indenting roller, can reduce the air-inclusion derived transfer defects of conventional techniques. Accordingly, even when the running speed of the sheet-form body is increased to improve productivity, the indented sheet having a regular pattern of fine indentations formed on a surface thereof can be manufactured with high-quality defect-free results. Further, according to the manufacturing method and apparatus of the present invention, the indented sheet having a regular pattern of fine indentations formed on a surface thereof can be manufactured with high-quality defect-free results at a high line speed and with good productivity.

摘要： In a manufacturing method of the present invention, a diffusion sheet having a flat size of a product size or more is laminated to a front surface and/or back surface of a lens sheet having flat size of the product size or more, and the stack is cut along its periphery into the product size, and the lens sheet and the diffusion sheet are bonded to each other at least one or more peripheral points thereof. This eliminates a step for individually cutting a number of films (sheets) into a product size, and a step for aligning the number of films (sheets) for lamination. In addition, the method does not cause a problem of waste of protective sheets, but provides advantages in both cost and quality. There is no problem caused in laminating a number of films, or problems caused by different thermal expansions/thermal shrinkages of a plurality of films.
摘要翻译：在本发明的制造方法中，将具有产品尺寸以上的平面尺寸的漫射片层叠到具有产品尺寸以上的平坦尺寸的透镜片的前表面和/或后表面，并且叠层沿着其周边切割成产品尺寸，并且透镜片和漫射片彼此的至少一个或多个外围点彼此接合。这消除了将多个膜（片）单独切割成产品尺寸的步骤，以及用于对齐用于层压的膜（片）数量的步骤。另外，该方法不会造成保护片的浪费的问题，而且在成本和质量两方面均具有优点。在层叠多个薄膜方面没有问题，或者由多个薄膜的不同的热膨胀/热收缩引起的问题。
