<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 (64) is positioned adjacent to the conveyor for receiving cut labels and applying them onto containers fed along the conveyor. A cutter assembly (200) is positioned adjacent to the labeling drum (64) for receiving a web of labels, cutting the web, and transferring a cut label onto the labeling drum (64). The cutter assembly (200) includes a stationary mounting plate (202) and a drive pinion mounted on the plate. A cutter roll frame (230) is received on the mounting plate (202), and includes a vertically oriented cutter roll (232) with upper and lower ends, a central axis, and a gear (244) at the lower end for meshing with the drive pinion and rotating the cutter roll (232). The cutter roll gear (244) size is directly proportional to the size of the cutter roll (232). The central axis of the cutter roll (232) is spaced farther from the drive pinion, and the outer surface of the cutter roll (232) is spaced farther from the label drum (64) for successive large diameter cutter rolls (232).</p> |
