<p>A beam provides a support for a series of rolls journaled side by side between bearing brackets. The bearing brackets are forked and movable vertically in relation to the beam. The relative movement of the brackets is controlled by, e.g., pressure bellows, diaphragm cylinders, pneumatic or hydraulic cylinders and the like. The rolls are journaled between the bearing brackets in pivot bearings mounted in the furcations of the bearings. Between these furcations there has been journaled a smaller diameter intermediate roll to establish a substantially continuous line of contact together with the rolls. By the aid of the control elements disposed between the beam and the brackets the shape of the contact line is changed as desired.</p> |
