ABSTRACT:
A method and apparatus for shaping a solid antiperspirant stick composition. The antiperspirant composition is produced in a generally cylindrical form having an oval or elliptical cross-section and the method and apparatus disclosed herein form the exposed end of the stick into a domed shape. A shaping mechanism comprises three shaped and heated cutting edges, each of which is arcuately oscillated with respect to the end of the stick within the plane of the major axis of the oval or ellipse. One pre-cut cutting edge is oscillated in one direction and makes a cut partially into one side of the exposed end of the stick. Rough cut and finish cut cutting edges are then arcuately passed through the end of the stick in the opposite direction.
