Claim:
An adhesive applicator, disposed in a location for glue application within a path along which sheet sheaves are conveyed, for performing cover-sheet binding processes with a downstream cover-sheet binding means, the applicator comprising: a glue container for receiving hot-melt adhesive; an applicator roll disposed inside said glue container; an apparatus casing internally adapted with said glue container; cooling means disposed alongside a glue application position inside said casing, for post-glue-application cooling of sheet sheaves; and control means for actuating and halting said cooling means, said control means being configured to (1) cool the apparatus casing interior by actuating said cooling means when a sheet sheaf is conveyed toward the glue application position; (2) halt said cooling means when adhesive is being applied to said sheet sheaf having been conveyed into the adhesive application position; and (3) reactivate said cooling means after adhesive has been applied to said sheet sheaf in the adhesive application position.
