  • Apparatus for applying glue to cores
    Patent number: 6871814
    Abstract: A glue applicator for a web winding apparatus applies a longitudinal stripe of glue to an elongated core. The stripe of glue may be applied by an elongated wire or bar, by a rotating roller, or by a sprayer. The glued core is moved by a core inserter into position for insertion into the winding apparatus so that the stripe of glue is upstream of the web and in position to contact the web at the start of a new winding cycle. A web pinch pad on the core inserter contacts the web and severs the web at the start of the winding cycle.
