  • Automatic vacuum feed and hold down assembly for camera system
    Patent number: 4814832
    Abstract: An automatic vacuum feed and hold down system is provided having a transport belt with vacuum grippers, a peripheral vacuum channel surrounding the platen, and a lead edge blow apparatus. In the preferred embodiment the transport belt consists of polyester fabric selectively coated with plastisol sealant to define a window area similarly shaped but smaller than the platen and suction grippers within the window area. In the preferred mode of operation a lifting apparatus raises the belt away from the exposed photosensitive sheet on the platen and the natural curl of the sheet, together with the lead edge blow, cause the sheet to release from the platen. The lifting apparatus then lowers the belt and suction is reapplied to the grippers, whereafter the belt and sheet are raised and advanced to deliver the exposed photosensitive sheet for processing.
