Abstract
A taper cover segment configured to fit circumferentially around a straight roller is disclosed. The taper cover segment comprising a main body having an inner surface and an outer surface, a plurality of ribs that are monolithic with the main body and extend radially inward from the inner surface of the main body. Each rib has a claw shaped edge that is configured to provide grip between the rib and the straight roller. A plurality of cavities is defined between adjacent ribs of the plurality of rib. A locking arrangement is monolithic with a first end of the main body, and is configured to detachably connect the taper cover segment with another taper cover segment to form a taper cover for encasing the straight roller. The taper cover segment defines a longitudinal axis, and a center of mass of the taper cover segment can be offset from the longitudinal axis.
