  • Apparatus for attaching endsheets without moisture wrinkles
    Patent number: 6093279
    Abstract: A machine for attaching a book cover to endsheets within an adhesive is set forth. The adhesive is applied while it is within a predetermined temperature range. The machine includes a housing, an application roller journalled within the housing, and a metering roller journalled within the housing. The metering roll is axially parallel to the application roller and nearly contacts the application roller at a nip. The region above the nip defined by the application and metering rollers, and two internal seals with the housing is an adhesive reservoir. The adhesive remains in this reservoir before it is applied by the application roller. The machine also includes a level detector which detects the level of the adhesive in the adhesive reservoir. The level detector is coupled to a controller and produces a low level signal when the level of the adhesive is below a predetermined level threshold.
