DEFINITION

Classification: 162/109

(under subclass 100) Processes for producing an essentially flat web or sheet having some irregularity or variation from the plane configuration, which variation is slight in proportion to the web's length and width so as not to destroy its essentially flat condition, and the webs or sheets so produced.

(1) Note. The irregularity may be produced during the deposition of the fibers or by a subsequent treatment of the undried web.

SEE OR SEARCH THIS CLASS, SUBCLASS:

218+, for processes for the production of discrete and finite shaped articles by deposition of fibers, which shaped articles may have a pronounced irregularity and be nonplanar.
