ABSTRACT:
The roller comprises a core and a shell secured to said core. The shell is made up of two coaxial pipes, i.e. an inner pipe secured to the core in the middle and an outer pipe fastened to the inner pipe in the middle and at the ends. This allows the shell to be made of small-diameter thin-walled pipes thus reducing the roller deflection and decreasing considerably the weight both of the roller proper and of the equipment utilizing said roller.
