Abstract:
1. A method of edge deleting, the method comprising: providing a low-E coating supported by a first major surface of a substrate having a polymer based temporary protective coating provided over at least the low-E coating on the first major surface of the substrate so that the polymer based temporary protective coating is located directly on and over the low-E coating; providing an apparatus, the apparatus comprising (1) a substantially horizontally oriented edge deletion table, (2) an edge deletion unit suspended above the edge deletion table, the edge deletion unit comprising a grinding wheel and a nozzle located proximate to the grinding wheel, (3) an aspirator located adjacent to the apparatus, and (4) tubing connecting the aspirator to the nozzle of the edge deletion unit, wherein at least part of the tubing has a diameter and/or opening of at least about 40 mm; providing the substrate supporting both the low-E coating and the polymer based temporary protective coating to the apparatus such that it advances down the edge deletion table; and allowing the grinding wheel of the edge deletion unit and the aspirator to cooperate to perform edge deletion on the low-E coating supported by the coated article and remove the polymer based temporary protective coating provided thereto, from a common area of interest.
