<p>A labeling apparatus for continuously labeling containers with printed labels from a continuous roll of backing material includes a continuous release liner web of backing material in roll form. The continuous release liner web of backing material has a plurality of labels adhered thereon at spaced-apart label regions using a pressure sensitive adhesive. The continuous release liner web of backing material is configured to allow the labels to be removed therefrom without damaging the labels. A feeding mechanism is configured to continuously dispense the continuous release liner web of backing material with the labels adhered thereon. A peel plate includes a peeling edge over which the continuous release liner web of backing material is drawn by the feeding mechanism. The edge of the peel plate has a shape that promotes a leading edge of the labels to loosen from the continuous release liner web of backing material as the corresponding label region is drawn over the peeling edge. A vacuum roller includes channels extending inwardly from a periphery of the vacuum roller. The channels are in communication with a vacuum source. The vacuum roller is arranged and configured (i) to engage a label at its leading edge prior to a leading edge of the label being loosened from the continuous release liner web of backing material by being drawn over the peeling edge of the peel plate and (ii) to capture the label and direct the label from the continuous release liner web of backing material to a periphery of a container as the vacuum roller rotates by overcoming the bond between the pressure sensitive adhesive and the continuous release liner web of backing material through use of a negative pressure applied to the label through at least some of the channels in communication with the vacuum source.</p> |
