摘要：Method for stabilizing a glide shoe loaded against an inner face of a revolvingmantle of a roll adjustable in zones. The glide shoe is supported by an articulated jointon a piston which loads the glide shoe with adjustable pressure. In order to ensurelubrication 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 theroll mantle, a shifting and/or steepening of compression pressure applied by the glideshoe through lubricant onto the inner face of the roll mantle is produced by means of awedge space within the front edge of the glide face, said shifting and/or steepening inturn generating a moment having a direction opposite to a direction of a momentproduced by frictional force of the glide face of the shoe. The thickness of the lubricantfilm is increased by this 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 machinemake use of the method described.
