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.
