Abstract

Improved expandable shaft, which is specially designed to support carrier coils of a sheet material wound on a tubular core or mandrel coupling to said shaft, and being of the type that incorporate a shaft itself on which a bushing is mounted in the periphery of which a plurality of longitudinally elongated, uniformly distributed flanges, projecting radially to the outside by a deformable pneumatic membrane at the expense of a source of pressurized air that accesses them through an inflation valve, are established. Because said flanges or jaws are located sharply off-center towards the free end of the bushing, while at the other end of said bushing a cone duly fixed thereto is established, so that said cone receives one of the ends of the coil mandrel, which adjusts to the same independently of its diameter, fixing said mandrel the coil at its end through the complementary flanges or jaws.
