Abstract

A system for applying pressure sensitive adhesive labels from a feed web with high position precision onto flat uniform size articles mechanically links the advance of the article to be labeled and the advance of the current label to be applied in unison, so that forward advancement speed of the article and the current label are matched exactly, independent of any speed variation in the application system. This is accomplished using a label following member that comes to rest at the trailing edge of a succeeding label and is freely allowed to follow the succeeding label as it advances on the web spaced downstream of the current label. Such following member is mechanically coupled to a pusher which advances the article to be labelled in the precise speed and relative location of the current label as it advances, thereby accurately placing the current label on the article as it peels from the continuous support web. As the label following member and the article pusher are always in exact unison with each other, any variation in their coupled speed of movement in the system is not significant so precision movement sensors are not required.
