Abstract

This disclosure relates to the manufacture of lites (glass sheets) which have at least a pair of thin spacers applied thereto which maintain the lites in spaced relationship when stacked upon pallets, wrapped and shipped. The spacers are preferably only partially adhered to the lites, either by weak bonding adhesive or electrostatically, and can be readily removed during end-use applications. The spacers are applied automatically during production runs of the lites, and the spacers are applied from above or from below relative to the path of travel of the lites.
