PUBLISHED NOVEMBER 23, 1971 sesame, 27 3o 22' \llllllllllllllllllllll A method of making a laminated roll for use in magnetic calenders wherein the roll includes a plurality of annular laminations installed on a concentric core under particular loading conditions which confer a stillness that prevents lamination separation in service. The method includes the steps of assembling the laminations in abutment with one another concentrically on a metallic core having a stop on one end and applying an axially directed compressive force to the laminations concurrently with a substantially equal but opposed axially directed tensile force to the core. The loading force applied is equal to about twice the level of loading at which it is desired to permanently preload the laminated roll. The laminations after being placed on the core are permanently locked in place under the compressive and tensile forces applied during assembly of the roll,
