Abstract
Improved non-electrostatic spray coating process and apparatus are provided. The process and apparatus of the present invention permit significant reduction in over-spray conditions as well as, the disadvantages and drawbacks associated therewith, without causing corresponding reduction in coating efficiency.
Claims15
An apparatus for spray coating at least one surface of a workpiece having a height H, said apparatus comprising:
- a. a plurality of vertically-oriented, linearly-configured spray means of number N for spraying with a liquid material said surface;
- b. means for conveying said workpiece in a travel path at a velocity V past said spray means, said spray means producing substantially identical elliptically-shaped spray patterns, each said elliptically-shaped pattern having a major axis height h, said spray means including adjustable means for spacing said spray means so that said patterns overlap each other with an overlap factor F within a range of between 10 and 50 percent of said major axis height;
- c. means for determining the position of said workpiece relative to said spray means;
- and
- d. means for activating said spray means to spray only when a workpiece is in a target position in said travel path.
2 more elements
Apparatus for holding a workpiece, and comprising:
- a. a housing having a slot dimensioned for insertion therein of an edge of said workpiece;
- b. at least one jaw means in said housing for bearing upon and locking said edge in said slot, said jaw means being actuable between an open and a closed position, said open position permitting insertion of said edge into said slot and said closed position locking said edge in said slot;
- c. a cam located in said housing for actuating said jaw between said open and closed positions, said cam being actuated by at least one arm mounted to said cam through an opening in said housing.
