ABSTRACT:
A scanner assembly for scanning labels for the presence of control marks as the labels are being fed to the labelling head of a labelling machine, the scanner assembly including a cross shaft rotatably supported on the labelling head below the path of movement of the labels, at least one radially projecting support arm on the cross shaft, the support arm being keyed to the cross shaft for slideable movement axially along the cross shaft to enable the position of the support arm on the cross shaft to be adjusted laterally; the outer end of the support arm being enlarged to provide a surface for supporting and guiding the labels along the path of label movement; a recess of predetermined depth in the support arm surface; a label scanning sensor in the recess for scanning labels as the labels move across the support arm surface to the labelling head; and manually operated gear means for rotating the cross shaft and the supporting arm thereon to enable the point where the sensor scans the labels to be moved along a predetermined arcuate path parallel to the direction of label movement during adjustment.
