<p>A labelling machine comprises a label supply spool support (la) for supporting a label spool (1) of label carrying web (lb), a label take up spool support (3a) for supporting a label take up spool (3) adapted to take up a portion of web, and a first motive apparatus (4) for transporting web along a web path between the supply spool support to the take up spool support, and a controller (10). The controller is configured to provide a control signal (10a) to the first motive apparatus, wherein the controller is further configured such that the controller provides a control signal to the first motive apparatus to accelerate the first motive apparatus between a first speed and a second speed by providing a control signal to the first motive apparatus to command the first motive apparatus to accelerate to a predetermined first intermediate speed intermediate the first and second speeds, then a control signal to command the first motive apparatus to accelerate to a second predetermined intermediate speed intermediate the first intermediate speed and the second speed, and then a control signal to command the first motive apparatus to accelerate to the second speed.</p> |
