Abstract

To provide a web processing device that allows tension adjustment with a simple structure. [Solution] The web processing apparatus according to this disclosure comprises a plurality of small rollers for transporting the web, a large roller that oscillates about a rotation axis and absorbs tension fluctuations of the web, and a processing liquid tank for storing processing liquid. The plurality of small rollers are arranged at equal intervals with respect to the center of the large roller when viewed from the front, and the web transported by the small rollers is transported while immersed in the processing liquid stored in the processing liquid tank.
