Title:
表面に微細な凹凸パターンを有するフィルムの製造方法および製造装置
Document Type and Number:
Japanese Patent JP5482202
Kind Code:
B2
Abstract:
Disclosed is a method for producing a film having a fine irregular pattern intermittently by 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. A main roll and an auxiliary roll arranged in parallel with the main roll are employed as a means for gripping a film. The main roll or a roll for smoothing out creases from the processed film is employed as a means for preventing the processed film from creasing.
