ABSTRACT:
In labelling apparatus for precision application of labels to continuously conveyed articles, labels are applied which have a pressure-sensitive adhesive backing releasably carried by a web. To provide precision in application, the leading portion of the label next to be applied is sensed and is separated from the web. A control device, on receiving a sensed label signal, determines the extent to which the leading portion of separated label extends from the web preparatory to article application. The control device resumes web movement to marry label speed with conveyed article speed in applying label to desired article location.
