Feed rolls with replaceable flute elements

摘要

A fluted feed roll has inner replaceable flute inserts which abut and are bolted to anchor pieces welded in place on a cylindrical roll body. Part of the inner longitudinal edge of the flute inserts bears directly against the surface of the roll body. Traction elements on the outer longitudinal edge of the flute inserts protrude radially outwardly beyond the anchor pieces.
