DEFINITION

Classification: 156/583.3

With significantly flexible platen:

(under subclass 583.1) Apparatus in which the flexible or resilient nature of the press surface is specifically defined.

(1) Note. Included herein is flexing of the press surface by a pressurized fluid acting either directly or indirectly on the press surface. Press surfaces indicated as merely flexible or resilient are not here unless the flexible or resilient surface is of a specialized nature. For example, alternating of pressure surface shape between planar and nonplanar during pressure application, plural layers of flexible or resilient material, portion only of press surface contains flexible material, etc..
