  • Patent number: 6649220
    Abstract: A compliance mechanism (10) is disclosed for maintaining a fluid applicator (47) in contact with the surface of object (71) for fluid application. The compliance mechanism includes an L-shaped bracket (15) having a first leg (17) and a second leg (19), each leg having a tab. A first dual acting fluid operated cylinder (32) is slidably positioned on the first leg (17) of the L-shaped bracket (15). First cylinder (32) has a piston rod that advances during fluid actuation of the first cylinder. A second dual acting fluid operated cylinder (35) is slidably positioned on the second leg (19) of the L-shaped bracket (15). The second cylinder (35) has piston rod that advances during fluid actuation of the second cylinder (35). A fluid applicator (47) is on first cylinder (32) for applying fluid to object (71). The first cylinder (32) allows fluid applicator (47) to move relative to the object in a second direction whereby fluid applicator (47) is maintained in contact with object (71) during fluid application.

  • Patent number: 5855673
    Abstract: An apparatus for wipe coating a perimeter edge of a panel part as well as simultaneous sections of either or both surfaces adjacent the perimeter edge, in which a wiper strip is advanced into a space between two movable guide blocks and past one or more deflector elements. When the panel part is inserted into the space, a shoulder is formed in the wiper strip to create contact with both a side surface and the perimeter edge, enabling coating of both simultaneously as the perimeter of the panel part is drawn through the space and in contact with the wiper strip. The deflector element can also be movably mounted to allow a variable depth of the side surface to be coated. Two wiper strips can also be used to wipe both sides of the panel part.
