  • Patent number: 6821345
    Abstract: An apparatus for coating sheet metal strip substrate with lubricant type laminate includes top and bottom roller coaters for pinching the metal therebetween to apply laminate. The roller coaters are movable between engaged and disengaged positions. Pneumatic cylinders for actuating the top and bottom roller coaters are operatively connected such that the top and bottom roller coaters can “float” or move vertically while at the same time pinching the metal strip therebetween. The roller coaters comprise roller coater carriages that carry applicator rolls between support rolls without the need to journal ends of the applicator roll. A spring biased applicator head applies laminate directly to one or more sections of the applicator roll.

  • Patent number: 6521044
    Abstract: An apparatus for coating sheet metal strip substrate with lubricant type laminate includes top and bottom roller coaters for pinching the metal therebetween. Each roller coater includes an applicator roll supported between three contact points provided by two support rolls and the sheet metal surface itself. As such the applicator roll can be without and axle and freely removable. The applicator roll is driven by the movement of the metal strip. The roller coaters are movable between engaged and disengaged positions. When in the disengaged position, support brackets on the top roller coater prevent the applicator roll from dropping and replace the bottom support of the sheet metal. Pneumatic cylinders for actuating the top and bottom roller coaters are operatively connected such that the top and bottom roller coaters can “float” or move vertically while at the same time pinching the metal strip therebetween.
