    摘要: A paperboard core suitable for use in winding yarns may include strips of paperboard wrapped about an axis and secured together to form an elongate structure defining a winding surface. A coating of a polymer such as polyvinylidene chloride covers the winding surface. The coating may be applied to the strips of paperboard prior to winding and/or applied to the winding surface after winding. The coating may comprise multiple layers of the polymer, which may be cured individually. The coating may also be applied so as to create a substantially uninterrupted coating along the winding surface. One method of applying the coating is by roll-coating.

    摘要: The present invention relates to a method for manufacturing of a stiffening element (1, 1′, 1″, 2) of composite material, which stiffening element is provided for attachment to a curved shell surface (9), said stiffening element (1, 1′, 1″, 2) comprises a web (3) and at least one flange (5), the outer surface (11) of which has a radius (R) of curvature corresponding with the curvature of said curved shell surface (9) The method comprises the following steps of: providing a substantial flat blank (19) of composite material; and folding said blank (19) along a first folding line (13), the curvature of which is defined by an imaginary three-dimensional intersection line (115) being derived from the radius (R) of curvature of the curved shell surface (9).
