DEFINITION

Classification: 156/285

(under subclass 60) Processes in which (1) pressure less than atmospheric is applied to the work during the association of the laminae or (2) where a force is exerted by a fluent medium directly onto the work during association of the laminae.

(1) Note. The reduced pressure or the fluid pressure may be applied to bring the lamina into contact or to effect more intimate contact of the laminae.
