A driving drum comprises a cylindrical body with a lining with cuts fixed thereon. The openings are parallel to the drum axis, which is equipped with control elements of belt deformation and a device for setting difference of deformations of control elements, which are located in the openings in radial planes of the drum with a minimum pitch without limitation of mutual deformation and are rigidly attached by some edges to the base of opening, and the other edges – protrude above the cylindrical surface of lining. The elements of control have elastic components in radial direction and flexible in the plane perpendicular to the axis of drum, their width does not exceed the width of allowable damage of a pulling unit. |
