摘要： A method of producing an embossed sheet includes the steps of allowing a flexible strip-shaped sheet to continuously travel, forming a coating layer by coating the surface of the sheet with a radiation curable resin, transferring a pattern of concavities and convexities on the surface of the emboss roller to the coating layer by winding the sheet around the rotating emboss roller, curing the coating layer by irradiating the sheet which is wound around the roller with radiation, releasing the sheet from the emboss roller, laminating a protective film on one or both sides of the continuously traveling sheet after releasing, and taking up the continuously traveling sheet after lamination in the form of a roll. According to the method, a high quality, defect-free embossed sheet having a fine regular pattern of concavities and convexities on the surface can be produced at high line speed with high productivity.

摘要： The apparatus is for forming a resin film from a resin for a middle portion to form a resin film main body of the resin film and a resin for edge portions to form both side edge portions in a crosswise direction of the resin film. The apparatus comprises: a feed block which includes a joining part where the resin for the middle portion in a molten state and the resin for the edge portions in a molten state are joined in such a manner as to enclose both side edges in the crosswise direction of the resin film main body with the resin for the edge portions; and an extruding die through which the joined resins are extruded to form the resin film. Thus, a method and apparatus for forming the resin film can avoid the inclusion of the resin for the middle portion in the trimmed-off selvages while preventing the film separation of the resins for the middle portion and for the edge portions, and therefore, increase the recyclability and the productivity of the resin film.
