Label unwinder – motorised, for rolls up to 500 mm
Motor-driven, the label unwinder pays off large rolls and hands the liner to the printer or dispenser right on cue. A sprung tension arm keeps the web calm while the drive copes with outer diameters up to 500 mm. Heavy duty from Arnsberg.
Why the Label unwinder?
Drawing heavy label rolls off by hand means fighting torn liner and uneven running. The label unwinder takes that strain away: its motor actively turns the roll, the stepless control matches the pace to the labeller, and the tension arm cushions every load change.
Why the Label unwinder?
Actively driven roll
Rather than merely dragging the liner through, the motor actively turns the label roll. Across the stepless range from zero to full speed, it synchronises pay-off with the dispenser or print head.
Large master rolls with ease
Where tabletop dispensers and hand feeding reach their limits, the unwinder keeps supplying: outer diameters up to 500 mm and roll weights up to 20 kg run off the mandrel under control.
Plug-and-run on 230 V
The full control sits inside the housing. One plug into the 230 V socket is enough and the unit works, with no separate control cabinet needed at the labelling station.
Docking onto the labelling line
Thanks to the tension arm and a sturdy aluminium profile, pull towards the applicator, inspection or finishing stays even. The unwinder lines up ahead of existing labelling stations.
Custom builds from the works
Your contact is Evotec itself. Differing cores, narrower or wider liners and customer-owned solutions take shape in our in-house special-machine shop.
Rugged and German-made
The torsionally stiff aluminium profile is designed for continuous use across multiple shifts. Design and manufacture take place in Germany, aimed at a long service life.
Drive and control around the label roll
The motor winds liner and labels off evenly while the built-in control holds web tension at a constant value. Print image and dispensing edge therefore stay repeatable.
- Pace stepless from zero to full, tuned to the dispenser
- Reversible running for inside- and outside-wound rolls
- Tension arm catches start-up and stop during pay-off
- Control on board, ready to run on 230 V
Where the label unwinder is used
Label printing in dispatch
Keeps thermal-transfer printers stocked with high-volume rolls, so multi-shift operation skips reloading and print throughput never breaks off.
Applicator on the packaging line
Passes the liner on at stable tension to the applicator, which marks cartons and containers automatically in time with the line.
Contract label converting
Loads slitting and re-rolling machines when large master rolls are rewound into smaller customer rolls.
Pharma and lab labels
Hands over delicate thermal labels with low vibration, so die-cut contour and barcode print precisely onto small containers.
Manual dispensing station
Positions heavy rolls at the hand workstation, so the operator no longer has to pull and their hands are relieved.
Food marking
Feeds weigh-price markers and date printers with liner, so best-before and price labels reach the goods jam-free.

Adaptation and integration into your labelling
If the series unit does not fit your roll or line exactly, we retool it. From a differing core to full coupling with the labelling station, we deliver it all from a single source.
- Cores beyond 76 mm for your roll winding
- Narrower and wider liner guidance for any label format
- Connection to applicator, print head or inspection point
- Mechanical and electrical fitting into existing equipment
