The shaft on which the rolls are mounted is of special steel and is carried in self aligning cylindrical double roller bearings of adequate size and capacity, fitted in housings and well sealed with labyrinths to prevent possible
entry of dust, foreign particles or moisture.
The gap between the rolls can be adjusted with the help of setting the position of the floating roll. This is done by adjustment bolts and insertion or removal of steel strips provided with the equipment.
Drive to both rolls is through individual flywheels which may be driven by a single motor or
separately by two motors.
