Label loop eliminates inertia in high speed pressure sensitive labeller 

Pago introduced a high speed pressure sensitive labeller that uses an air cushion to support a variable length buffer loop of labels between the unwind and dispensing beak, eliminating inertia in the system and allowing high speed without risk of web snatch or breakage. As a result of the buffer loop system, which allows the label reel of the new Pagomat 6/3 to unwind smoothly in continuous motion while labels are dispensed in intermittent motion to suit product pitch, very high dispensing speeds can be achieved with particularly short labels. Depending on label length, which can be 10-300mm, the new machine can run at dispensing speeds up to 120 metres a minute. In addition, the main drive uses a servo motor with short acceleration times to ensure accuracy at high speed, typically ±0.5mm at the dispensing edge. A separate stepper motor drive with control via a dual dancing roller arrangement with two sensors is employed on the backing paper rewind to eliminate snatch and risk of breakage.
