Latest Patents

Ehrola holds a patent for a "Method for stabilizing a glide shoe of a roll adjustable in zones." This invention focuses on 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. The method ensures lubrication of the glide face between the glide shoe and the inner face of the roll mantle. It achieves this by creating a shifting and/or steepening of the compression pressure applied by the glide shoe through lubricant onto the inner face of the roll mantle. This innovative approach generates a moment that increases the thickness of the lubricant film, thereby enhancing the performance of the glide shoe.
