ABSTRACT:
An apparatus is disclosed for forming concave tape wrapped composite structures. The apparatus utilizes a mold having a cylindrical concave surface with a mounting plate mounted for rotation at each end thereof about a point on a longitudinal axis of the concave surface. A longitudinal shaft is mounted to each mounting plate a selected distance from the longitudinal axis and extends parallel thereto. A tape dispenser carriage is mounted to the longitudinal shaft and is movable along the length thereof. A radial shaft is mounted through the tape dispenser carriage such that the longitudinal axis of the radial shaft passes through the longitudinal axis of the concave surface and along a radius of the concave surface. A composite tape dispenser is mounted at the lower end of the radial shaft and in a preferred embodiment of the present invention a rack and pinion gear system is utilized in conjunction with both the longitudinal shaft and the radial shaft to allow tape to be applied to the entire concave surface of the mold.
