In various embodiments, a feeding device may comprise a support having feed cylinders arranged in a free end of a respective supporting arm and driven in rotation, wherein the supporting arms in a supported end are journalled in the support on shafts extending in parallel with each other and are pivotable about the shafts between a home position and a pivoted work position, and wherein the supporting arms are mutually connected to each other via a system of articulated links and by means of the links are forced to pivot jointly about their respective shafts, and a movement damping element, which is separate from the support, is integrated in the system of links and independently from the support configured to brake the return movement of the supporting arms from the pivoted position.

A feed roll comprises a roll having a rotary axis, flutes fixed on the roll, mounts fixed on the roll between the flutes, each mount having a seat spaced apart from the outer surface of the roll and replaceable flute elements detachably and matingly engaged in the seats of respective mounts and extending outward beyond the mounts. The replaceable flute insert element comprises an elongated plate body having an inner longitudinal edge, an outer longitudinal edge, and a backing face extending between the inner longitudinal edge and the outer longitudinal edge and the inner longitudinal edge and the backing face configured to matingly engage the seat of the mount. The flute insert element further comprises the outer longitudinal edge being formed with a traction element and the plate body having a plurality of bolt holes therethrough for registering with the bolt holes of the mount element when the plate body and the seat are matingly engaged.
