PROBLEM TO BE SOLVED: To make it possible to uniformly and stably maintain the taking-up state of products by providing the transverse ends of raw sheets with belt-like coating regions of the coating thickness larger than the coating thickness of a central part coating region surface and forming these belt-like coating regions to diagonal stripe patterns. SOLUTION: The coating raw sheets (plastic films) 1 are continuously coated and taken up by using, for example, a reverse gravure coating device, etc. Both ends of the coating part are provided with the longitudinal stripe-shaped belt-like coating regions 3 thicker by 1 to 10μm than the thickness in the central part coating region 2 part, by which the contact pressure between the coating raw sheets (plastic films) 1 during taking-up of the central part coating region 2 part is reduced. The belt-like coating regions 3 are designed to execute pattern coating of such diagonal lines as to generate the force acting on the outer side of taking-up with respect to the tightening in winding of the take-up. As a result, the deformation of the coating raw sheets (plastic films) 1 is prevented.
