DEFINITION

Classification: 425/429

(under subclass 425) Apparatus comprising plural means, each imparting a separate diverse motion to the shaping means, which motion contribute to a distributing or compacting function.

(1) Note. Traveling support means for a mold which merely presents a mold to a shaping area are not here; see appropriate subclasses provided for plural molds or subclass 453 for a dynamic mold carrier, per se.

(2) Note. When one of said means is a vibrator directly vibrating a shaping surface, the disclosure is here. However, a tamp rod acting on the stock is not considered means to impart motion to a shaping surface and has been collected in subclass 431. Further, the indiscriminate motion caused by a vibrator is not considered diverse motion for this subclass--thus, it follows that electrical or pneumatic vibrators which produce indiscriminate vibrating motion of a shaping surface are not here but are in subclass 432.
