A laminate film manufacturing method is capable of preventing thickness unevenness of a cured layer and preventing wrinkling of the entire laminate film. A laminate film is manufactured by applying a coating solution including an active radiation curable resin to a surface of a first film that is continuously transported in an application part to form a coated film in a lamination part, laminating a second film that is continuously transported on the coated film to sandwich the coated film between the first film and the second film, and in a state in which the coated film is sandwiched between the first film and the second film, winding the first film around a backup roller and irradiating the coated film with infrared rays from an ultraviolet irradiation device while continuously transporting the first film to cure the coated film in a curing part so as to form a cured layer.

A solution casting apparatus includes a drive roller as a conveying means. The drive roller conveys a polymer film peeled from a belt, the polymer film still containing a solvent. The drive roller has corrugation valleys and corrugation peaks formed on a peripheral surface along a circumferential direction of the drive roller. Each of the corrugation valleys and the corrugation peaks has a substantially semicircular cross section. The corrugation valleys and the corrugation peaks are disposed alternately in an axial direction of the drive roller. A pitch Pbetween the corrugation valleys and a pitch Pbetween the corrugation peaks are in the range of 0.01 to 2 mm, and a height Hfrom a lowest point of the corrugation valley to a highest point of the corrugation peak is in the range of 0.01 to 1 mm. A curvature radius Rof the corrugation valley and a curvature radius Rof the corrugation peak are in the range of 0.1 to 0.5 mm.

A web conveying apparatus is provided with a plurality of web guiding rollers. The web guiding rollers convey a web on which a functional material has just been coated in a coating section. Concave portions and convex portions that have a substantially semicircular cross section are alternately formed on a peripheral surface along a circumferential direction of each roller. A pitch Pof the concave portions and a pitch Pof the convex portions are in the range of 0.01 mm or more and 2 mm or less. A height Hfrom a lowest point of the concave portion to a highest point of the convex portion is in the range of 0.01 mm or more and 1 mm or less. A curvature radius Rof the concave portion and a curvature radius Rof the convex portion are in the range of 0.1 mm or more and 0.5 mm or less.

A web winder of a turret winding type is provided with a first spindle secured to a first drive shaft. A second spindle is secured to a second drive shaft. Positions of the first and second drive shafts are changeable in the web winder. A changeover device changes over winding of a web wound about the first spindle to winding about the second spindle. A cutting drum is disposed on a first side with respect to a web path of the web, and has a cutter for cutting the web in a width direction thereof. A receiving drum is disposed on a second side with respect to the web path opposite to the first side. A drum support arm supports the cutting and receiving drums in a rotatable manner and in a manner of contacting drum peripheral surfaces of the cutting and receiving drums on each other.

A coating device for coating a coating solution on a web has a roller and a weir which partially constructs a solution store space. In the solution store space the coating solution is stored. When the web sequentially moves in a direction, the roller rotates and the solution in the solution store space is supplied on the web. Thereby a part of the solution overflows the weir such that another part of the solution may remain on the web to have a constant width in a widthwise direction of the web. A drying device has plural drying zones in which the web is fed after the coating of the coating solution. One of the drying zones is neighbored to the coating device. A top of the plural drying zones is constructed of a blow regulation member so as to confront to the solution on the web. The blow regulation member has holes through which is exhausted a gas evaporated from the layer of the solution on the web.

In a web transporting apparatus that transports a web while floating the web by jetting air from jetting holes formed in a transporting surface to the web, edge rollers that is rotatable and supports edges of the web are provided at both ends of the transporting surface. The web is transported while the edges of the web are supported by the edge rollers, and thus a floating amount of the web can be kept. Also, the supplied air can be prevented from escaping from a space between the transporting surface and the web through the edges of the web, and the web can be stably floated and transported with little air.
