(under subclass 123) Processes in which a web or sheet is deposited on each of a plurality of separate forming means and subsequently united after substantial felting of each web or sheet has taken place.
(1) Note. This subclass takes processes in which a plurality of separately formed webs are united while one of the webs is still in contact with its forming means, as well as those in which pressure rolls, momentarily in contact with the work, effect association of the webs.
(2) Note. This subclass does not take products. For products of processes classifiable in this subclass, see the appropriate one of subclasses 123+.
SEE OR SEARCH THIS CLASS, SUBCLASS:
123, through 131, for processes of producing multilayer
waterlaid webs or sheets involving the use of a single forming means, or in which a second layer is waterlaid in situ directly on the surface of a previously formed layer, and for products formed by processes classified in this or indented subclasses (132+).
300+, for apparatus for carrying out processes classified in this or indented subclass.
