FILAMENT WINDING APPARATUS ABSTRACT OF THE DISCLOSURE A filament winding apparatus (10) has a bobbin slidably, nut non-rotatably, received on a tube mounted to a base. A cylindrical case (14) has an internal circumferential groove (20) with gear teeth (21,22) which mesh with an orbiting cylindrical bail (38). A base mounted sun gear (36) located within the case (14) meshes with bail gear teeth (42) driving it along both a circular path and about itself as an axis. A filament (46) to be wound passes through an eyelet (24) axially mounted to the case (14), through the bail (38) and secured to the bobbin. Rotation of the sun gear (36) winds the filament onto the bobbin while not subjecting the filament to sharp bending stresses, and during which frictional engagement is distributed over extended eyelet (24), bail (38) and filament (46) surfaces.
