Abstract: A pivoting polishing block assembly comprises a torsion arm having a molded polishing block joined thereto in pivoting relation about the central axis of the torsion arm. The molded polishing block comprises a polishing block holder having a plurality of openings formed therein, and an abrasive pad formed thereover composed of an abrasive, moldable material. An apparatus for cleaning and polishing rolls, which includes the pivoting polishing block assembly, is also provided.

Abstract: Apparatus for automatically polishing run-out table rolls, comprising: (a) a run-out table polisher take-up reel operatively connected to a carrier belt having abrasive material affixed thereto; and (b) control means for paying out and then retrieving the carrier belt onto the run-out table in response to one or more permissive signals indicative of the operational status of the run-out table. A method of automatically polishing run-out table rolls, comprising: (a) receiving one or more signals indicative of the operational status of a run-out table; (b) processing the signal(s) to determine whether a permissive condition for polishing the run-out table rolls exists; (c) in response to a determined permissive condition, paying out from a take-up reel a carrier belt having abrasive material affixed thereto; and (d) retrieving the carrier belt onto the take-up reel.

Abstract: The invention relates to an apparatus and method for polishing run-out table rolls. The apparatus includes a polishing block assembly having linked abrasive blocks and a positioning apparatus to position the blocks in contact with the surface of the run-out table rolls that are to be polished. The method includes the steps of positioning the assembly over the rolls, lowering the assembly into contact with the rolls, transporting the assembly in a linear direction over the rolls to effect the polishing and thereafter removing the assembly from the rolls.

Abstract: The present invention relates to a tandem pneumatic/hydraulic reciprocating cylinder with an integral oil reservoir. The invention may be used to impart reciprocating motion to adjustable apparatus used in the cleaning and polishing of roll assemblies.

Abstract: The present invention relates to an apparatus for cooling a traveling strip of heated material. The apparatus includes a cooling header comprising an external pipe having disposed therein a plurality of internal pipes having discharge holes. The external pipe has an exit which communicates with the discharge holes, and further includes a first chamber which communicates with a source of air and a second chamber which communicates with the first chamber and the internal pipes.

Abstract: Method and apparatus for automatically cleaning a roll for handling sheet stock while in service, including signale ended reciprocally actuated scrubbing of a fully roll surface width polishing surface swingingly engaged with the roll surface to provide effective cleaning action without leaving residual scars on the roll surface. Single ended actuation of the scrubbing action is enhanced with special self aligning bearings.

Abstract: An apparatus is provided for cleaning and polishing the surface of cylindrical rolls. The apparatus is characterized by a shaft connected at each end thereof to end units. The end units are movable toward and away from the surface of the roll to be cleaned and polished. The end units are also adapted to reciprocate the shaft along its longitudinal axis. At least one abrasive stone attachment means, including an abrasive stone, is attached to the shaft such that the abrasive stone can be positioned in substantial contact with the surface of the roll.

Abstract: The present invention relates to a self-adjusting apparatus for use in cleaning the surface of endless belt conveyor belt apparatuses and the like. The apparatus is characterized by a blade tip which is positioned to contact the surface of the conveyor belt at a location where the conveyor belt is in contact with a head pulley, snub pulley, idler roller, or the like. The blade tip is attached to a rotatable and translatable support structure. The support structure comprises a plurality of tortion units which permit the blade tip to move in response to deformations of the surface of the conveyor belt during the operation of the conveyor belt.

Abstract: The present invention relates to an apparatus for use in cleaning scraps of metal and other materials from rollers used in the rolling of sheet stock. The apparatus is characterized by a knife-edge blade which is positioned to contact the surface of such rollers. The blade is attached to a support structure adapted for ready positioning of the blade against the roller.
