Abstract: The invention is to friction rolls for working elongate members, e.g., webs or strands, such as crimper rolls, draw rolls, yarn package drive rolls comprising a roll having a generally cylindrical external surface and a ceramic, e.g., alumina, mixtures of alumina and titania, chromia, zirconia, or metallic carbide, e.g., tungsten carbide, coating bonded to the external surface, the coating being laser-engraved, that is, having a plurality of laser-formed depressions having a pattern covering substantially the entire exterior working surface of the roll and providing a uniform, wear-resistant surface texture over substantially the entire working surface.

Abstract: A comminuting and shredding arrangement having a cutting and/or tearing mechanism for comminuting paper cardboard and synthetic materials. A housing is rotatably mounted and has inwardly projecting paddles which feed the material to be comminuted towards a cutting and tearing mechanism operatively mounted in said housing, thereby recycling the material to be comminuted therethrough.

Abstract: In a forage harvester having a rotatable cutterhead and adjacently-positioned shearbar, an upper rear feed roll is mounted above and forwardly of the shearbar for pivotal movement relative to an upper front feed roll by a pair of arms which interconnect the rolls. A tensioning assembly is coupled to each of the arms. An actuatable latching mechanism is connecting to the tensioning assembly and movable to a first position for placing the tensioning assembly in a first condition in which the rear feed roll is biased toward a lower operative position adjacent the cutterhead and shearbar.

Abstract: A towed type wheeled chopping implement is adapted to be connected in trailing relation to a harvesting combine to receive leaves, stalks (such as stover) and the like, of the crop being harvested from the combine. The implement includes a hopper having a conveyor therein for conveying the stover (or crop leaves, stalks and the like) to driven feed rolls which direct the stover into a chopper device, where the stover is finely chopped. The chopped stover material is then directed by conveyor means to a blower device which blows the chopped stover material through a conduit into a collection structure such as a truck body or the like.
