Abstract
A mechanism for applying adhesive to a sheet comprising a plurality of glue applicators comprising valves or nozzles adapted to form a charge of adhesive at the tip of each. The sheet is moved toward the nozzles to permit adhesive spots to be deposited on the sheet. The nozzles have periods of deactivation after which they are reactivated. A cleaning and moistening sponge (or a tray with appropriate fluids) is provided to maintain the adhesive in the nozzles in usable condition during periods of deactivation so that the adhesive may be immediately used and deposited on the sheet upon reactivation of the nozzles.
