A method for producing elastic laminates, comprising: feeding a first continuous elastic film, stretching the first continuous elastic film in a transverse direction, applying the first continuous elastic film on an outer circumferential surface of a transfer wheel rotatable around a first axis of rotation, holding the first continuous elastic film transversally stretched on said outer circumferential surface of the transfer wheel, cutting longitudinally the transversally stretched first continuous elastic film on said outer circumferential surface of the transfer wheel so as to split the first continuous elastic film into at least two parallel continuous elastic films, holding said at least two parallel continuous elastic films in a transversally stretched state on said outer circumferential surface of the transfer wheel, applying a first nonwoven web on an outer cylindrical surface of an anvil wheel rotatable around a second axis of rotation parallel to the first axis of rotation, transferring said at least two parallel continuous elastic films from the transfer wheel onto the first nonwoven web held on the outer cylindrical surface of the anvil wheel, applying a second nonwoven web on the anvil wheel above said at least two parallel continuous elastic films, and forming an elastic laminate by joining the first and second nonwoven webs through said at least two parallel continuous elastic films.
