WRINGER ROLL

摘要

PURPOSE: A wringer roll is provided to prevent the slip of a rubber layer from a roll shell by applying the normal force to between a rubber layer and a roll shell. CONSTITUTION: A wringer roll comprises a cylindrical roll shell(100) and a rubber layer(200). The rubber layer surrounds the exterior of the roll shell and directly contacts to the roll shell. Grooves are formed on at least one of the roll shell and the rubber layer, and protrusion parts(210) inserted in the grooves are formed on the other one. The grooves have a spiral shape. The roll shell is made of metal, and the rubber layer is in a cooled state.
