<p>A labeling machine can rapidly change the size of labels cut from a web of labels to match different diameter containers which are then fed onto containers moving along a conveyor. A labeling drum is positioned adjacent to the conveyor for receiving cut labels and applying them onto containers fed along the conveyor. A cutter assembly is positioned adjacent to the labeling drum for receiving a web of labels, cutting the web, and transferring a cut label onto the labeling drum. The cutter assembly includes a stationary mounting plate and a drive pinion mounted on the plate. A cutter roll frame is received on the mounting plate, and includes a vertically oriented cutter roll with upper and lower ends, a central axis, and a gear at the lower end for meshing with the drive pinion and rotating the cutter roll. The cutter roll gear size is directly proportional to the size of the cutter roll. The central axis of the cutter roll is spaced farther from the drive pinion, and the outer surface of the cutter roll is spaced farther from the label drum for successive larger diameter cutter rolls.</p> |
