ABSTRACT:
Apparatus for drawing a web of sheet material from a roll wound on a core which is supported to rotate freely about its axis as the web is drawn off the roll. A brake has a movable element connected to a shaft which is rotatable about the axis of the core independently of the core. First and second coaxial members are mounted to turn with the shaft and are mounted for independent axial movement toward and away from the core. When the first member is moved axially into frictional engagement with the core, the core turns the shaft. When the shaft is turning in unison with the core, the second member is moved into interlocking engagement with the core to mechanically connect the core and the shaft.
