Deformed example 1
[0189] Although in the first embodiment described above, the case where the first coating liquid Q1 is applied with the first nozzle 12 directed toward the portion of the strip-shaped base material S1 supported by the back-up roll 11b is given as an example. Although described, it is not limited thereto.
[0190] Figure 8 (a) and (b) are figures which show the structural example of the part of coating unit 10A, 10B which concerns on a modification.
[0191] Such as Figure 8 As shown in (a), in the coating unit 10A, the discharge position P1A is set at a position shifted to the +Z side from the backup roll 11b. In this case, the first nozzle 12 applies the first coating liquid Q1 with the discharge port 12a directed toward a portion of the strip-shaped substrate S1 supported away from the back-up roll 11b (for example, a portion offset to the +Z side). When a foreign matter is caught between the lower surface S1b of the strip-shaped base material S1 and the backup roll 11b...
no. 2 approach
[0194] Next, a second embodiment will be described. Figure 9 It is a figure which shows an example of the coating unit 210 which concerns on 2nd Embodiment. In the above-mentioned embodiment, the configuration using the belt-shaped base material S1 formed of a resin material such as PET as the base material has been described as an example. However, in this embodiment, the material of the belt-shaped base material, etc. One embodiment is different. Hereinafter, the difference from the first embodiment will be mainly described.
[0195] Such as Figure 9 As shown, in the transport unit 211 of the coating unit 210 according to the present embodiment, a strip-shaped base material S2 formed of a metal material such as stainless steel is used as the base material. Forming the strip-shaped base material S2 from a metal material makes it difficult to form wrinkles and the like. The strip-shaped base material S2 is formed endlessly, and is stretched between the backup roll 211a, ...
no. 3 approach
[0201] Next, a third embodiment will be described. Figure 10 It is a figure which shows an example of the coating unit 310 which concerns on 3rd Embodiment. In this embodiment, the structure of the conveyance part 311 which conveys the strip-shaped base material S1 differs from 1st Embodiment. Hereinafter, the difference from the first embodiment will be mainly described.
[0202] Such as Figure 10 As shown, the conveying unit 311 has a strip-shaped base material (base material) S1, a base material delivery roller 11a, a backup roll (first roll) 11b, a backup roll (second roll) 11c, and a backup roll as in the first embodiment. 11d, base material winding roller 11e and delivery roller 11f.
[0203] Moreover, the conveyance part 311 has conveyance member S3 and backup roller 311a, 311e. The conveyance member S3 is formed in a belt shape, and is formed in an endless shape using a metal material such as stainless steel, for example. The conveying member S3 is stretched bet...
