Application of THEODORE BOSTROEM Title: WINDER DRUMS FOR STRIP SLITTING LINES ABSTRACT OF THE DISCLOSURE Apparatus for winding a plurality of metal strips on a non-collapsible drum to form a plurality of coiled strips. In one form of the invention, the drum is formed with spaced slots in the periphery thereof in which are positioned rail members and interconnected wear members. Core members are positioned loosely around the periphery of said drum for receiving the individual slit strips, and expansible hoses are positioned in each slot radially inwardly of the rail. Fluid pressurization of the hoses functions to expand the same and force said rail and wear members radially out- wardly into frictional contact with the core means thereby creating tension in said metal strips and consequent tight winding of the narrow strips on the core means. The pressure can be partially reduced to permit the tightly wound strip coils to slip on the drum surface and the loosely wound strips to continue rotation so as to remove the slack from the strips, thereby compensating for unequal thicknesses of the marginal and median strips. In a further form of the invention, the hoses are positioned in the drum for direct pressure contact with the core members. -1-
