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.
Claims13
A glue applicator for applying a longitudinally extending stripe of glue to an elongated cylindrical core comprising:
- a frame,
- means for supplying elongated cores,
- means for moving a core from a first position at said core supplying means to a second position,
- a glue reservoir,
- an elongated glue applicator movably mounted on the frame for movement between a first position in the glue reservoir to a second position in which the glue applicator extends parallel to and is in contact with a core in the second core position whereby a longitudinally extending stripe of glue may be applied to a core.
A glue applicator for applying a longitudinally extending stripe of glue to an elongated core comprising:
- a frame,
- means for supplying elongated cores,
- a core inserter rotatably mounted on the frame,
- means for moving a core from the core supplying means to the core inserter, and
- a sprayer movably mounted on the frame for movement in the longitudinally dimension of an elongated core for applying a longitudinally extending stripe of glue to a core.
A glue applicator for applying a longitudinally extending stripe of glue to an elongated cylindrical core comprising:
- a frame,
- means for supplying elongated cores,
- a glue applicator roll rotatably mounted on the frame,
- means for moving a core in a direction which extends transversely to the longitudinal dimension of the core from a first position at said core supply means and into contact with said glue applicator roll and to a second position, whereby the glue applicator roll contacts the core along a longitudinal line as the core moves from the first core position to the second core position.
