Edge coating apparatus

An edge-coating apparatus for simultaneously applying liquid coating material to adjacent non-parallel planar surfaces of the edge portions of work pieces, said apparatus comprising:

• a. a flexible endless belt having an inner drive side and an outer liquid-transporting and applying side including
• 1. a first upper surface portion being outwardly and downwardly inclined in a plane different from the planes of the non-parallel planar edge surfaces of the work piece to be coated, an upper edge on said first surface portion of the belt, adapted to be in moving contact, at the point of application of the coating material, with a downwardly facing planar surface of the edge of the work piece being moved past said apparatus, a lower edge on said first surface portion of the belt, adapted to lightly contact, at the point of liquid application, a planar surface on the edge of the work piece which is non-contiguous and non-parallel with said downwardly facing surface thereon, said first upper surface portion on the liquid-applying side of said belt being further adapted to apply coating material to at least two adjacent non-parallel planar surfaces of said work piece edge portion;
• 2. a second liquid-applying surface portion on said belt having a surface configuration substantially similar to that of a portion of the edge of a work piece to be coated thereby, said second surface portion extending from and being downwardly inclined with respect to said first surface portion;
• and
• 3. a substantially vertical surface portion on said belt extending downwardly from said second surface portion,
• b. rotatable mounting means for said endless belt, said mounting means comprising a plurality of pulleys all mounted for rotation in the same horizontal plane;
• c. means for imparting rotation to the mounting means;
• d. means for supplying liquid to the liquid-applying side of said belt at a point preceding the point of liquid application;
• e. for bringing the edge portion of a work piece and the liquid-applying side of said belt into movable contact with each other;
• and
• f. resilient means mounted for reciprocal movement in a horizontal plane for biasing said liquid-applying side of said belt into and maintaining its contact with the edge portion of a work piece being moved therepast.
