DEFINITION

Classification: 162/218

(under subclass 100) Processes involving depositing fibers on a surface so as to form a product of definite and limited dimensions and shape as distinguished from a web of a definite length.

(1) Note. This and indented subclasses relate to forming articles by "pulp molding".

(2) Note. Processes of this group of subclasses usually result in an article having a nonplanar configuration, but this is not necessary.

SEE OR SEARCH THIS CLASS, SUBCLASS:

109+, for processes of forming webs or sheets which are irregular in configuration, but which irregularity is not such as to destroy its essentially flat condition.

231, for articles, produced by a process classifiable in this or indented subclasses (218+) and not provided for elsewhere.

382+, for apparatus for carrying out the processes of this group of subclasses.
