US Patent 8720067 Contoured roller system and associated methods and resulting articles of manufacture

A contoured roller set and associated systems and methods are disclosed herein. A male roller having a convex surface and a pair of female rollers each having a concave surface can receive a generally thin sheet of material and impart a doubly-curved shape to the sheet. The convex and concave surfaces of the male and female rollers can have a radius of curvature chosen to match a radius of curvature of the sheet of material. The rollers are positioned and shaped to urge the sheet between the female rollers to cause the sheet to curve toward the male roller.
