Abstract:
1. A coater for applying thin films onto a sheet-like substrate, the coater having a substrate transport system adapted for conveying the substrate along a path of substrate travel extending through the coater, the substrate transport system including two conveyor loops separated by an upward coating deposition gap, at least one of the conveyor loops traveling around a generally horizontal row of upper rotatable bodies which support the weight of the substrate during conveyance, and traveling around one or more underside rotatable bodies during conveyance, the one or more underside rotatable bodies being positioned below the row of upper rotatable bodies such that upper rotatable bodies at each of two ends of the row of upper rotatable bodies have a conveyor wrap of less than 180 degrees, the coater having a source of coating material adapted for delivering coating material upwardly through said gap onto a bottom major surface of the substrate as the substrate is conveyed along a desired portion of the path of substrate travel, said desired portion of the path of substrate travel extending over the upward coating deposition gap.
