    • 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.
    • 一种标签机,其中压敏粘合背衬的标签可释放地粘附到沿着从分配辊到卷取辊的路径移动的背衬条。 将标签从背衬带上沿着所述路径从第一站从旋转的施加器滚筒上移除,并且将这样移除的标签从施加器滚筒转移到在第二站处连续呈现的物品。 改进包括扫描单元,比较器单元和去除单元。 扫描单元位于第一站之前,用于读取出现在粘附到所述背衬条上的标签上的标记。 比较器单元与扫描单元相关联,用于将标签上的标记与预选标准进行比较,并且用于在标准和不正确标签上出现的标记不匹配的情况下生成控制信号。 去除单元响应于控制信号,以在第一和第二站之间的位置从施加器滚筒移除不正确的标签。
