DEFINITION

Classification: 162/315

(under subclass 289) Apparatus having means for bringing a pulp slurry into association with a foraminous mold whereby a fibrous body may be formed thereon.

(1) Note. In this and the indented subclasses may be found either the subcombination of the stock directing means, per se, (note subclass 336, for example) or the directing means in operational association with the foraminous mold.

(2) Note. The directing means may be any instrumentality for either bringing the pulp slurry from the supply and into association with the mold or merely to maintain the slurry against the mold so that felting to form a product can occur. Thus even a claimed cylinder vat (subclass 323) is sufficient structure of a stock directing means for this

subclass in that it maintains the stock against the mold.
