Abstract
A labelling machine with three pad head where during labelling of articles every other pad is skipped, each pad having vacuum holddown ports in the periphery to temporarily attach a label during the labelling process, a control valve for controlling admission of vacuum to each pad so that a label is attached to and carried by the pad into labelling relation with an article brought forward by a conveyor belt, and a vacuum distributing valve to limit the vacuum supply to the control valve so that no vacuum can be admitted by the control valve to a skipped pad thereby preventing undesirable loss of vacuum to the atmosphere through the absence of a label to close the pad holddown ports.
