Abstract
An apparatus for labelling conveyed articles applies glue to the rear surfaces of labels and applies the glued labels to the articles. The apparatus comprises a device for passing the rear face of the label by a glue applicator and then applying the glued label to an article. In the absence of a label on the device, the pad for carrying labels is withdrawn as it passes the glue applicator. The label transferred to a pad is held on its face by the use of vacuum. When a label maintains vacuum on the pad face, a brake in response to the maintained vacuum is actuated to prevent withdrawal of the pad, as it passes the glue applicator. In the absence of a label, the brake is inoperative to allow the pad to withdraw and avoid application of glue to the pad face.
