Abstract
A labeling machine in which pressure sensitive adhesively backed labels are releasably adhered to a backing strip moving along a path from a dispensing roll to a take-up roll. The labels are removed from the backing strip onto a rotating applicator drum at a first station along said path, and the thus removed labels are transferred from the applicator drum to articles being successively presented at a second station. The improvement comprises a scanning unit, a comparator unit, and a removal unit. The scanning unit is positioned in advance of the first station for reading indicia appearing on the labels adhered to said backing strip. The comparator unit is associated with the scanning unit for comparing the indicia on the labels with a preselected standard and for generating a control signal in the event of a mismatch between the standard and the indicia appearing on an incorrect label. The removal unit is responsive to the control signal for removing the incorrect label from the applicator drum at a location intermediate the first and second station.
