Document Type and Number:
Japanese Patent JP6776165
Kind Code:
B2
Abstract:
Provided are a method for manufacturing and a device for manufacturing a laminated film that can control application width of a functional liquid, maintain uniform film thickness for an applied film, and suppress loss of the functional liquid. A film (10) is delivered in a state wherein a puddle (22) of a functional liquid (21) is in contact with one surface of the film (10) so as to apply the functional liquid (21) to the one surface of the film (10), thereby manufacturing a laminated film provided with the film (10) and a functional layer (20) comprising an applied film (20M) of the functional liquid (21) formed on one surface of the film (10). Here, a sealing material (32) prescribing both end positions of the puddle (22) in the direction of width of the film is disposed aligned to the application width for the functional liquid (21), and the applied film (20M) is formed by the functional liquid (21) by applying liquid pressure to the puddle (22) from outside of the film width of the sealing material (32) while suppressing outflow of the functional liquid (21) from the vicinity of the sealing material (32).
