DEFINITION

Classification: 162/289

(under subclass 232) Apparatus specifically adapted or peculiar to the handling of work of great length relative to its cross-section which work is continually produced or treated.

(1) Note. In this and the indented subclasses may be found, for example, devices for producing from a slurry endless webs of paper, endless tubes of fiber containing material and also means specialized to this class for treating such products after initial forming on a foraminous forming surface whether or not the forming device is claimed.

(2) Note. For devices producing discrete articles search must be made in subclass 375 or the subclasses following it in the schedule.
