摘要

Improved reel for rolling films, characterized in that its hub, centered and linked to the winding drum provided with non-slip means by a few protruding elongated points in the marginal holes of the belt, is capable of joining in rotation with two axes of diameter, and reducing suitably the diameter of said recess to allow the passage of the lower diameter shaft, in both cases being perfectly adjusted the reel to the shaft.
