Abstract: A drive mechanism for a paper machine controlled deflection roll or the like having a tubular roll shell driven by a ring gear with driving pinions driving the ring gear and each of the pinions mounted on support shafts with the support shafts carrying planetary gears driven by a sun gear. The sun gear is carried on a power input shaft mounted in vertical slides. The planetary gears are horizontal of the sun gear so that the sun gear can shift and be self-positionable to equalize the load on the gear teeth as the sun gear drives the planetary gears with a thrust bearing on the shaft and helical teeth between the sun gear and the planetary gears.

Abstract: An extended nip press for removing water from a traveling web in a paper machine including a press roll with an elongate shoe having a concave surface facing the roll and forming an extended nip therebetween with the shoe pressed to the roll and mounted to accommodate movement to form a wedge of lubricant between the shoe and a belt with the ends of the belt closed by end walls to contain lubricant within the belt and a flexible radial connection between the end walls and the ends of the belt so that the belt will follow the curvature of the nip beyond the ends of the shoe and will flex only in a single plane of the nip.
