摘要

A method and apparatus are illustrated for converting a brake on a rotating turret arm 12 of a paper unwinding stand 10 from a disc brake unit to a drum brake unit which includes providing an adapter bracket 30 by means of which the turret arm 12 accommodates drum brake structure in place of the disc brake unit. The adapter bracket means 30 includes an attachment flange 32 which attaches directly to a mounting plate 22 of a removed disc brake unit 20. A support flange 34 is carried by the attachment flange which pivotably supports brake shoe means 36, 38 which engage a brake drum 46 adapted for connection to an end 16a of the paper roll shaft 16. The drum is hollow and includes a rotary union 60 through which a cooling fluid is circulated.
