The present invention provides a web processing device comprising: a coating unit which coats a long strip of web by using a bar having in an axial direction at least two spiral grooved portions differing in the spiraling direction of the spiral groove; and a cutting unit which cuts the coated web in the lengthwise direction in a coating position along the boundary between the two spiral grooved portions. By using the bar having two spiral grooved portions, any foreign matter can be quickly shoved out to prevent it from inviting a seam flaw and, moreover, the adverse effect of any seam flaw occurring along the boundary between the two spiral grooved portions can be eliminated, with the result that high-quality processed webs can be manufactured at a high yield.
