Abstract
A universal pin ring for use in securing filament in a stationary position with respect to a mandrel during a filament winding process is disclosed. In the preferred embodiment, the universal pin ring has two rows of pins along its length. The pins of the first row are adapted to serve as anchor pins to secure filament in a stationary position with respect to a mandrel. The pins of the second row are adapted to serve as guide pins to cause filament to quickly conform to the contour of a mandrel after turning of the filament during filament winding, thereby minimizing the size of the turnaround area. In some applications, both rows of pins would serve to anchor filament. In other applications the guide pins serve both to guide filament and to anchor filament that has slipped from an anchor pin. Reinforcing ribs and flex grooves on the universal pin ring are also disclosed.
