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.
Claims8
An apparatus for applying a wipe coating material to perimeter edge surfaces of a part extending at an angle to side edges of said part, said apparatus comprising:
- a machine frame;
- two aligned guide blocks, each having a guide surface facing the guide surface of the opposite guide block, said guide blocks movably mounted on slide means supported by said machine frame to allow said facing guide surfaces to move toward and away from each other, said slide means including bias means resiliently urging relative movement of said guide blocks towards each other;
- a deflector element interposed between said guide blocks and having an end surface extending orthogonally in a direction across a space between said guide surfaces to form a step with one of said guide block guide surfaces;
- an elongated flexible wiper strip separate from said deflector element extending through said space between said guide surfaces and movable past said deflector element;
- dispensing means for said coating material positioned adjacent said guide blocks and directing said coating material so as to cause said wiper strip to be soaked with said coating material to allow a coating thereof to be wiped onto said part surfaces when said part is inserted between said guide blocks with a section of said side surface against one of said guide block surfaces with a first segment of said wiper strip interposed and a section of said perimeter edge surface urged against said deflector element with a second segment of said wiper strip interposed, said second segment thereby formed into a step shape by engagement of said perimeter edge surface to be in conformity with said side and edge surfaces of said part;
- and,
- index feed means for periodically advancing a fresh length of said strip from a supply thereon into said space between said guide surfaces.
