The i-Web Gluer applies remoistenable glue, rub-off inks, encapsulated fragrances, scratch-off materials, and aqueous coatings in patterns to the bottom side or top side of the web. The unit is installed between the last printing unit and the dryer in the case of remoistenable or coating, at the beginning of the inline for Wet Flap applications and in a multitude of positions for other flexo gluing applications. In all cases, the gluers are supplied with a four roll gluing system. The metering roller is driven by its own variable speed motor and has a manual adjustment for fine adjustment of the gap between it and the Transfer Roll in which the material thickness is created. A Plate cylinder is supplied with a reel rod lock-up for mounting the glue pad. The Impression cylinder has a continuous “Cut-off” size surface with special chroming. The plate and impression cylinders are mounted in eccentrics pneumatically actuated on and off impression. Units include motorized sidelay register for the plate cylinder and motorized 360-degree circumferential registration.
