DEFINITION

Classification: 19/304

Fluid propelled to condenser:

(under subclass 296) Method or apparatus wherein fibers are carried or conveyed in a gaseous stream for accumulation, assembly, or collection in web form upon a foraminous or perforate receiving surface or across a fiber entrapment area formed by a plurality of spaced receiving surfaces.

(1) Note. This group of subclasses is distinguished from subclasses 202+ wherein a batt or sheet is formed and subsequently disintegrated; the product of subclasses 304+ is a permanent sheet, web, or batt.

SEE OR SEARCH THIS CLASS, SUBCLASS:

88, and 89, for combined picking, i.e., fiber liberation or separation, cleaning, and fiber condensing.

148, for assembly of a fibrous article by screen condensing.

202+, for combined fiber cleaning and condensing.

205, for conveying fibers in a fluid propelling current or stream to a cleaning operation.

SEE OR SEARCH CLASS 209, Classifying, Separating, and Assorting Solids,

12.1+, 133+, and 250 for delivery of solid material suspended in a fluid to sifters for purpose of this class (209).

264, Plastic and Nonmetallic Article Shaping or Treating: Processes,

517+, for vacuum deposition, collection, or assembly of fibers to form a nonwoven web combined with an operation of this class (264): and subclass 121 for projecting fibers in a moving gas stream in the formation of a nonwoven web by uniting randomly associated fibers as provided for by this class (264).

406, Conveyors: Fluid Current, Appropriate subclasses for mere entrainment and conveyance of fibers in a gaseous medium.
