  • Patent number: 5211349
    Abstract: An elastomeric sleeve adapted to be mounted on a reel for winding strip into coil form has metal inserts adjacent a gripper slot opening for preventing flat spots in the coil. The sleeve is designed to permit sufficient expansion when the reel is expanded so that the gripper opening is not pulled apart and a widened gap is not formed therebetween. Preferably, slits are provided on the inner periphery of the sleeve for this purpose. Alternatively, a collar can be mounted on the outboard end of the segment bridging the gripper opening for enhanced structural rigidity to prevent the sleeve from pulling apart the gripper opening upon expansion of the reel.

  • Patent number: 4852198
    Abstract: Apparatus is disclosed for brushing the edges of electroplated metal strip to remove excess plating metal therefrom. In a first embodiment for brushing the narrow face edges of the strip, a cup brush is mounted on a carriage having a motor thereon for rotatably driving the brush. The carriage is slidably movable in a transverse direction of the strip. A device urges the carriage inwardly toward the strip so that the brush is maintained in constant contact with uniform pressure against the strip edge. In a second embodiment for brushing the broad surfaces of the strip adjacent to the strip edge, a disc brush is mounted on a carriage having a motor thereon for rotatably driving the brush. Again, the carriage is slidably movable in a transverse direction of the strip. A device urges the carriage inwardly toward the strip so that the brush is maintained in constant contact with a uniform portion of the width of the strip near the edge thereof.

  • Patent number: 4832276
    Abstract: A compound elastomeric sleeve is provided for installation onto a segmented reel for preventing creases in metal strip wound into coil form thereon. A relatively thin, easily compressible outer sleeve is bonded to a thicker, more rigid inner sleeve. The dual hardness compound sleeve prevents creases yet retains its shape sufficiently for easy removal of a coil wound thereon from the reel. The invention includes a method for preventing creases from forming in metal strip which is to be wound into coil form on a segmented reel on which the compound sleeve is mounted.

  • Patent number: 4573620
    Abstract: Apparatus for controlling the jerk or shock loading of the wire rope used to apply tension to move a galvanizing or pickle line's horizontal looper car. The apparatus includes a vertical spindle affixed to the frame of the looper car. A drum having a radially extending arm is provided to be rotatable about the spindle. The arm is provided with an intermediate region to anchor the wire rope and a terminal region to cooperate with a resilient shock absorbing means which may comprise a polyurethane pad. Such shock absorbing means includes a bracket affixed to the looper car frame. A spring-biased bolt connects the arm to the bracket while a resilient pad is provided intermediate the arm and the bracket.
