  • Patent number: 5897747
    Abstract: An extended nip press having a concave shoe which is supported on a hydraulic actuator which urges the shoe against a backing roll. A pair of opposed profile control hydraulic actuators apply a pure couple about the load support line formed by a bearing pin which transmits the support load from the hydraulic actuator to the shoe. A leading hydraulic actuator is positioned in front of the load support line and pulls down on the shoe. A trailing hydraulic actuator is positioned behind the load support line and pushes up on the shoe. The leading hydraulic actuator and trailing hydraulic actuator are equally spaced from the load support line and have equal hydraulic actuator area and are connected to the same hydraulic reservoir. Thus the hydraulic actuators exactly balance each other out except for the couple or torque which they apply about the load support line.
