Abstract
An automated stencil dryer includes a holder mechanism for holding a stencil, a discharge mechanism for discharging air against a stencil positioned in the holder, and a driver mechanism operatively coupled to the discharge mechanism for automatically moving the discharge mechanism so that compressed air can be discharged fully across the surface of the stencil. In one embodiment, the discharge mechanism includes a pair of air knives disposed parallel to one another on opposite sides of the holder so that the stencil is between the air knives when the stencil is positioned in the holder. The air knives are oriented inward toward the stencil when the stencil is positioned in the holder so that air discharged from the air knives is directed against the stencil. In another embodiment, the discharge mechanism includes a pair of air distribution pipes disposed parallel to one another on opposite sides of the holder so that the stencil is between the distribution pipes when the stencil is positioned in the holder. A plurality of orifices are disposed along each distribution pipe through which air is discharged. The orifices are oriented inward toward the stencil when the stencil is posit…
