Abstract
A method of manufacturing a filament wound article is practiced by winding overlying filamentary layers on a form such that those portions of the wound layers which are covered by overlying layers include incomplete or discontinuous portions thereof whereby portions of the layers which are not covered by overlying wound layers are of a minimum thickness for enhanced accuracy in the approximation of a desired smooth thickness profile.
Claims6
A method of forming a tapered filament wound article by winding a band of juxtaposed filaments about a form having a longitudinal winding axis, said method being characterized by the steps of:
- (a) defining first, second and third longitudinally spaced stations on said form, said second station being located between said first and third stations, the girth of said form at said first station being greater than at said third station.
- (b) continuously winding said filament band about said form between said first and third stations until the entire girth of said form at said second station is covered with a layer of said filamentary material of desired thickness while portions of the girth of said form at said first station remain uncovered with said filamentary materials and
- (c) continuously winding said filament band about said form between said first and second stations until the entire girth of said form at said first station is covered with a layer of said filamentary material of desired thickness.
