DEFINITION

Classification: 100/306

Endless conveyor-type press:

(under subclass 305) Apparatus wherein the means to subject the material to a compressive force includes a pliable movable web or belt supported at its extremities by rollerlike members, against which the material is pressed during the movement of the material by the web or belt from one position to another.
