DEFINITION

Classification: 162/308

(under subclass 289) Apparatus having means positioned adjacent the foraminous forming surface and acting directly on the pulp material before it is removed therefrom.

(1) Note. In this and the indented subclasses may be found devices which in some way modify the characteristics of the finished product by a physical action on the stock either while still in a state of suspension (note subclass 311) or after felting but while still on the mold, but in either case the action on the fibers must occur adjacent the mold surface while the fibers are in contact with the surface.

SEE OR SEARCH THIS CLASS, SUBCLASS:

208, for processes for the treatment of the slurry on the mold surface.

290, for the combination of a forming mold and separate drying means for the product after removal from the mold.

297, for apparatus in which pneumatic pressure or vacuum means act directly on the stock mold surface.

305, for the combination of a foraminous mold and means subjecting the product to pressure after removal from the mold.
