Abstract:
A method of manufacturing a laminated structural body having two web layers with unidirectionally arranged strands sandwiched therebetween, comprising the steps of:delivering a cylindrically curved web in a direction parallel to a central axis thereof in a state where said web is kept in a cylindrical shape, said web having an elongation of 100% or higher in a transverse direction thereof; discharging a polymer liquid from a spinning head, which is disposed in said cylindrical web and rotated about the central axis of the cylindrical web, toward an inner surface of said cylindrical web to spin strands of the discharged polymer liquid and laminate the strands on the inner surface of said cylindrical web, wherein all strands of said discharged polymer liquid are laminated on the inner surface of said cylindrical web; and folding flatwise said cylindrical web with the strands laminated thereon to sandwich said strands between the two folded layers of the web.
