Abstract
(EN)
Provided are a film manufacturing method in which uneven thickness of a coating is suppressed for a longer period of time, and a film roll utilizing the method. This method for manufacturing a film (12) using a film manufacturing facility (30) comprises a liquid discharge start step, a liquid deposition step, a preliminary application step, and a main application step. In the liquid discharge start step, discharging of an application liquid (43) from a slot die (44) is started. In the liquid deposition step, the application liquid (43) is brought into contact with a base material (21). In the preliminary application step, a leading-end lip of an upstream block is exposed in a state where the application liquid (43) is applied to the base material (21). After the preliminary application step, the application is continued to form a coating (22) of a layered film (12) which is to serve as a product part.

L'invention porte sur un procédé de fabrication de film dans lequel une inégalité d'épaisseur d'un revêtement est supprimée pendant plus longtemps et sur un rouleau de film utilisant le procédé. Ce procédé pour la fabrication d'un film (12) à l'aide d'une installation de fabrication de film (30) comprend une étape de début de déversement de liquide, une étape de dépôt de liquide, une étape d'application préliminaire et une étape d'application principale. Dans l'étape de début de déversement de liquide, le déversement d'un liquide à appliquer (43) par une filière plate (44) est commencé. Dans l'étape de dépôt de liquide, le liquide à appliquer (43) est mis en contact avec un matériau de base (21). Dans l'étape d'application préliminaire, une lèvre d'extrémité avant d'un bloc amont est exposée dans un état où le liquide à appliquer (43) est appliqué sur le matériau de base (21). Après l'étape d'application préliminaire, l'application se poursuit pour former un revêtement (22) d'un film feuilleté (12) qui est destiné à servir de partie de produit.
