ABSTRACT:
A pneumatic handling and recoating apparatus for handling workpieces, such as glass, is provided. The apparatus utilizes a holding device operatively connected to a vacuum assembly. The holding device engages workpieces by vacuum and subsequently releases them by a burst of gas. The burst of gas also facilitates the application of a coating material, such as a stain-retardant agent, to a workpiece upon release from the holding device.
