DEFINITION
Classification: 162/293
(under subclass 289) Apparatus in which an endless molded product is formed on a molding surface of a limited length.
(1) Note. In this subclass may be found, for example, apparatus for producing an endless waterlaid tube of pulp material on a short foraminous core through which the carrier fluid is removed from the pulp, the endless tube as it is formed being continuously removed from the core.
