Abstract:
1. A labelling machine comprising: a supply spool support adapted to receive a supply spool of label web; a take-up spool support adapted to form a take-up spool of the web from which at least some labels have been removed; a motor arranged to turn the take-up spool; a controller to control operation of the motor; and a linear displacement sensor operable to sense linear displacement of the web, and provide a signal indicative thereof; a second sensor configured to sense an edge of a label adhered to the web; wherein a web path is defined between the supply spool and the take-up spool, and the controller is configured: to receive the signal provided by the linear displacement sensor, to monitor linear distance moved by the web along the web path based upon the signal provided by the linear displacement sensor; to determine at least one property relating to the displacement of the web based on the signal provided by the linear displacement sensor, the at least one property being selected from the group consisting of magnitude, direction and rate of displacement of the web; and to control the motor to turn the take-up spool based upon the received signal so as to cause controlled predetermined linear movement of a web along the web path and onto the take-up spool.
