    after passing through the rollers, the resin compound is passed through a rigid regulating plate disposed downstream of the rollers whereby pressure variation in the resin compound being fed is suppressed and the resin compound is formed into a plate-like shape, having a constant thickness, and wherein the lower film slides on a band-like floor, and wherein said regulating plate is supported by support rods that have adjusting members incorporated therein, and wherein the adjusting members are adjustable in order to maintain or adjust a gap between said regulating plate and said band-like floor.
