ABSTRACT:
A spray of ink, paint, or other marking liquid is formed and sprayed through a stencil member for marking a part with a stencil character. Various means are provided to periodically move the stencil member for removal of marking fluid to keep the system clean. In one system, the stencil member is rotatable and marking fluid is removed periodically by centrifugal force by rotating the member at a sufficient speed. Removal of the marking fluid may be facilitated by the application of solvent or fresh marking fluid. In another embodiment, the stencil member is moved to a marking liquid removal location where the marking liquid is removed by suction, solvent action, and the like. The removed marking liquid may be collected by providing an absorbent member positioned to receive the removed liquid, or by providing collecting gutters or the like.
