Abstract
A chemical vapor deposition coater, for depositing a stripe of coating material onto a hot glass substrate, comprises a coater body, including upstream, downstream, and side evacuation ducts, seal means for preventing CVD reactant from contaminating the atmosphere exterior to the coater, and independently controlled evacuation means for removing spent reactant from the reaction zone in such a manner so as to produce a stripe of coating material having a uniform thickness across the width thereof.
