<p>The system changes over label magazine boxes in a labelling machine, the empty one being replaced by a fresh one in the interval between extractor members reaching the extraction point. Two or more boxes can be delivered close together in a direction at right angles to the unstacking direction by means of rails, chains, guides etc. The box in the extraction position can be moved to and fro in the unstacking direction of the labels. The pair of boxes can be moved to and fro together so that either the one or the other is in the extraction position, by a first drive, while a second drive moves the one in this position to and from the extractor member.</p> |
