Abstract
A method of spraying a powder onto a substrate includes the steps of mounting the substrate in a fixed position; mounting a spray nozzle such that an outlet end thereof confronts the substrate; moving the spray nozzle such that a locus on the spray nozzle moves along a zig-zag pattern; and spraying the powder from the spray nozzle onto the substrate during the movement of the spray nozzle. The step of mounting the spray nozzle includes mounting the spray nozzle to a first oscillation link, and mounting the first oscillation link to a reciprocable slider. The step of moving the spray nozzle includes oscillating the first oscillation link relative to the slider, and reciprocating the slider during oscillation of the first oscillation link. The step of mounting the spray nozzle further includes mounting the slider to a second oscillation link. The step of reciprocating the slider includes oscillating the second oscillation link about a pivot point. The step of oscillating the second oscillation link includes positioning a revolving member in a slot formed in the second oscillation link, and revolving the revolving member. The step of oscillating the first oscillation link includes positioning a further revolving member in a slot formed in the first oscillation link, and revolving the further revolving member.
