Abstract
Disclosed is a method and apparatus for shaping a top surface of a product, such as an antiperspirant or deodorant product, to have a compound-curved shape. The apparatus includes at least one cutting blade which moves inward and outward in a second direction while the product passes by in a first direction perpendicular to the second direction, such that the cutting blade cuts the top surface of the product to have a desired profile in the first direction. The cutting blade itself can have a desired profile along a third direction perpendicular to the first and second directions, to impart to the top surface of the product a desired profile in the third direction. A plurality of cutting blades can be used, to incrementally remove product material to form a final shaped product surface. The product cut off in forming the shaped surface can be reclaimed for re-use. The apparatus can also include stationary blades, and can be used to form a product having a shaped top surface with a profile having different radii of curvature in the same direction.
