Document Type and Number:
WIPO Patent Application WO/2016/142441
Kind Code:
A3
Abstract:
A method is provided of manufacturing a wrapped object, comprising a first segment (6) and a second segment (7) connected to each other by a curved transition segment (8) having a common tangent with the first segment (6) and a common tangent with the second segment (7), respectively. The method comprises the step of providing a mandrel (9) with a surface structure to define at least part of the shape of the first segment, of the shape of the second segment and of the shape of the transition segment in between, and the step of wrapping, one or more elongate elements (4, 5) over the mandrel (9) and bonding the one or more elongate elements (4, 5) to itself and/or each other so as to provide the first segment, the second segment and the transition segment as a continuous structure. The mandrel is provided with a fortification (11) at least at the position of the transition segment, the fortification (11) being configured to support the one or more elongate elements (4, 5) forming the transition segment (8) against inward-directed forces, with respect to the direction of curvature of the transition segment (8), while wrapping and/or bonding the one or more elongate elements (4, 5) to form the transition segment (8).
