Latest Patents

Juhani Alajoutsijarvi holds a patent for a "Method for stabilizing a glide shoe of a roll adjustable in zones." This method involves stabilizing a glide shoe that is loaded against the inner face of a revolving mantle of a roll. The glide shoe is supported by an articulated joint on a piston, which allows for adjustable pressure. To ensure proper lubrication between the glide shoe and the roll mantle, the method introduces a shifting and/or steepening of compression pressure through a wedge space at the front edge of the glide face. This innovative approach generates a moment that increases the thickness of the lubricant film, thereby enhancing the glide shoe's performance.
