The slits include slits having different slit lengths. A flow quantity of the molten resin at the slit is changed by changing the intervals of the slits, length of the slits or by changing the temperature of the molten resin at the slits.

Abstract: A method for manufacturing a sheet having a fine shape transferred thereon, in which a sheet-like base made of a thermoplastic resin is placed between an imprint mold and an intermediate base and the sheet-like base is then pressed by a pair of pressing plates to imprint the fine shape of surface irregularity of the imprint mold to the sheet-like base. The sheet-like base is pressed such that, when pressing force of the pressing plates is maximum, an imprinting pressure difference is present in an imprinting surface of the imprint mold, a maximum imprinting pressure section is present in the imprinting surface, and a portion where the imprinting pressure is minimum is not present in the imprinting surface. The method achieves uniform and highly accurate shape transfer without trapping of air.

Abstract: An object of the present invention to provide a sheet manufacturing method and a sheet manufacturing die, in which a process of extruding a molten material from the die and winding it around a cooling roller can be performed at a high speed such as 60 m/min or more, and with which a sheet having a uniform thickness and a smooth surface can be obtained. In order to effectively charge the sheet with static electricity, the distance between paths of product portion and end portions of the sheet from a die to a cooling roller is reduced by adjusting the temperature of the sheet at the end portions thereof. The die is constructed such that the sheet is not influenced by deformation of a slit formed in the die, which is caused by heat expansion of the die and adjustment operations.
