ABSTRACT:
A glue cell apparatus for applying glue in a web printing unit is disclosed, which apparatus includes one or more self-contained modular units that have a finite width in the direction of the width of the web to which glue is applied. The modular units are carried and mounted upon a rail structure that extends substantially across the full width of the web and a drive shaft is also provided which also extends substantially the same distance. Each of the glue cells preferably has a transfer cylinder that is driven by the drive shaft that is operably connected and driven by the gluing and/or coating machine, and a metering roller subassembly having a metering roller which calibrates the thickness of the layer of glue that is ultimately applied to the web. The metering roller has an internal hydraulic motor which drives the same. In an alternate embodiment, a pan roller subassembly is also provided.
