Abstract
Improvements in the assembly of the film drums in cinematographic apparatuses, essentially characterized by the fact that the roll is supported on a film concentric with the axis of the drum and operatively arranged to rotate freely on itself, linked by means of support thereof, with respect to a core through which the drum shaft passes in a coaxial arrangement, this core comprising means for coupling to the drum plate and means for retaining said concentric rotating element in the axial direction.
