ABSTRACT:
A glue applicator for applying glue to a paper web used in the manufacture of paper cores is disclosed. A drive roller having a surface of frictional character rotates a glue applicator roller and a doctor roller, these rollers coupled by sprockets and a chain. The doctor roller is adjustable so that a gap between the doctor roller and glue applicator roller may be adjusted, adjusting thickness of a layer of glue applied to the paper web. A motor having an overrunning clutch is coupled to the glue applicator roller and doctor roller, so that during intervals when the paper web is not passing through the glue applicator, the glue applicator roller may be continuously rotated in liquid glue, preventing glue from hardening on the glue applicator roller and doctor roller.
