Abstract
A method for forming shaped fibrous articles. The method involves introducing at least a portion of a fibrous element into a shaping tool and subjecting the fibrous element in the shaping tool to ultrasonic energy. This imparts the shape of the shaping tool to the surface of the fibrous element. The apparatus has a guide-holder to receive and removably retain a fibrous element and an ultrasonic shaping tool which can be applied to the fibrous element. The shaping tool has a recess corresponding to a predetermined shape for the article. Preferably, the shaping tool and guide-holder are reciprocally moveable with respect to one another.
