Referring to Figure 1, a labeling machine 10, includes a vacuum label wheel 11 which is used to transport labels from a label feeding device (not shown) to articles fed to a labeling station (not shown). Typically, label wheel 11 includes a vacuum chamber which periodically communicates with holes on a peripheral portion of the wheel to provide thereon a vacuum pressure. This pressure is used to hold labels being trans-ported by the wheel from the label feeding device to articles at said station. The vacuum chamber of wheel 11 is coupled by a tube 12 to a valve 13, and valve 13 is coupled by a tube 14 to a vacuum pump 15.
