ABSTRACT OF THE DISCLOSURE Method for stabilizing a glide shoe loaded against an inner face of a revolving mantle of a roll adjustable in zones. The glide shoe is supported by an articulated joint on a piston the glide shoe with adjustable pressure. In order to ensure lubrication of the glide face between the glide shoe and the inner face of the roll mantle, within an area of a front edge of the glide face as seen in a direction of rotation of the roll mantle, a shifting and/or steepening of compression pressure applied by the glide shoe through lubricant onto the inner face of the roll mantle is produced by means of a wedge space within the front edge of the glide face, said shifting and/or steepening in turn generating a moment having a direction opposite to a direction of a moment produced by frictional force of the glide face of the shoe. The thickness of the lubricant film is increased by the moment in the area of the front side of the glide face. Moreover, a glide shoe and a press roll or calender roll adjustable in zones for a paper machine make use of the method described.
