Abstract: A roller head securable to the discharge end of an extrusion machine, wherein the roller head has a pair of rollers each rotatable between a pair of arms pivotable about an axis transverse to the extrusion machine. Each roller is movable with respect to the other roller and to the axis of the extrusion machine by a pair of pressurizable cylinders arranged between the pivotable arms. The rollers are rotatable, even in their separated state, by an articulated drive system which permits roller rotation during machine output and during roller support arm movement. The rollers are permitted to "float" on a hydraulic suspension system utilizing an accumulator wherein the separation of the rollers is dependent upon the volume of extrudite being forced therethrough.

Abstract: A mechanism for inducing a crossing of one axis of a roll with respect to the axis of a second roll on a calender roll machine, to correct for varying amounts of roll deflection under varying operating loads. The mechanism includes a pair of biased levers which are pivoted on a frame diametrically across from one another against a bearing box on a calender roll. The roll has a mechanism at each end thereof. The levers are biased by incrementally movable pistons which when actuated, swing the respective ends of the calender roll in an arc about its midpoint to effectuate the controlled skewing of its axis with respect to the axis of a calender roll thereadjacent.
