DEFINITION

Classification: 156/62.2

(under subclass 60) Processes which include forming a lamina by assembling individually distinct particulate material from a fluent mass and adhesively bonding the particles to each other and then uniting the lamina thus formed to itself or another lamina.

(1) Note. The distinguishing characteristic of this subclass is that the material used in forming the lamina is handled as a fluent mass as differing from those processes in

which each particle is individually handled or positioned.
