Patent ES-8206364-A1 (ES)
Title: Method of manufacturing a filament wound article
IPC: B65H54/64
Filed: 1981-10-19
Abstract: Elongate articles of non-circular cross section such as those of an airfoil cross section are constructed by winding filamentary material in layers about a form between a pair of spaced turnarounds generally conforming in shape to the cross sectional shape of the form. Adjacent layers are continuously wound by winding the filamentary material across the edges and outer face of each turnaround while reversing the direction of relative longitudinal displacement between the filamentary material and the form. The shape correspondence between the turnarounds and the form effect a minimization of expanse between the turnaround edge and form surface, thereby minimizing bridging of the filamentary material between those two members.
