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.
Claims12
A roller for applying a uniform load across the width of a processed sheet material comprising:
- an elongate core;
- and
- an elongate shell assembly defining a hollow interior space, said core being disposed within said interior space, said shell assembly comprising an inner pipe fastened at its mid-portion to the mid-portion of said core and an outer pipe coaxially extending over said inner pipe and fastened to the inner pipe at the mid and end portions thereof, said outer pipe being substantially non-bendable under the load supplied by the roll to the processed sheet material.
