DEFINITION

Classification: 162/355

(under subclass 354) Apparatus provided with means imparting a shaking or reciprocating motion to the flexible endless band which motion is transverse to the general longitudinal motion of the band.

(1) Note. The motion is usually for the purpose of causing better felting of the slurry during dewatering and forming on the mold.

SEE OR SEARCH THIS CLASS, SUBCLASS:

209, for processes for forming by felting and/or dewatering including the step of vibrating or agitating the slurry on the mold surface.

311, and 313+, for means separate from the mold for treating the stock on the molding surface.
