<p>A labeler for applying labels to articles is provided. The labeler includes a label application device having an opening in an end thereof. The label application device is expandable when subjected to pressure. The labeler also includes a positioner for supporting the label application device and moving the label application device between a label pick-up position and a label application position. A vacuum source and a pressure source are also provided which can be selectively connected to the label application device such the label application device is subject to pressure when adjacent the label application position and subject to vacuum for picking up and retaining a label on the label application device at the label pick-up position. The labeler also includes a flow control element having at least one flow control passage therein which defines at least one air flow path through the flow control element to the label application device opening. The flow control passage is configured to allow air flow through the air flow path and out the label application device opening when pressure is applied to the label application device, but being effective to delay the air flow from reaching the label application device opening.</p> |
