Abstract: The present invention relates to a method of producing a prepreg, in which a matrix resin is applied to a reinforcing fiber sheet, where the sheet can continuously run without clogging due to generated fuzz, even at a high running speed, and where the sheet can be efficiently impregnated with the matrix resin. The prepreg is produced by a method which includes a step of allowing a reinforcing fiber sheet to pass horizontally or slantingly through the inside of a coating section storing a matrix resin to apply the matrix resin to the reinforcing fiber sheet, where the coating section includes a liquid pool and a narrowed section which are in communication with each other, where the liquid pool has a portion whose cross-sectional area decreases continuously along a running direction of the reinforcing fiber sheet, and wherein the narrowed section has a slit-like cross-section and has a smaller cross-sectional area than the largest cross-sectional area of the liquid pool.

Abstract: A method for producing a film having a fine irregular pattern intermittently includes feeding a film to be processed intermittently from upstream side to the vicinity of the surface of a die having a fine irregular pattern, transferring the pattern to the surface of the film by pressing the film against the surface of a die, stripping the processed film on which a pattern is formed from the surface of a die, and then feeding a new film to be processed to the die, wherein the processed film is stripped from the surface of a die by gripping and moving the processed film to the upstream side, and then the processed film is fed by a length of intermittent feed to the surface of a die while preventing the processed film from creasing.

Abstract: A method for manufacturing a sheet having a fine shape transferred thereon, in which a sheet base made of a thermoplastic resin is placed between an imprint mold and an intermediate base and the sheet 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 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.
