ULTIMA 250 is a fully automatic, high-speed stretch film slitter rewinder. It cuts jumbo rolls up to 700 mm wide into narrower rolls and rewinds them at up to 1,200 m/min – or 1,500 m/min with the double servo motor option, producing stretch film hand rolls, machine rolls and cling film rolls.
The slitting unit cuts from 50 mm × 10 rolls up to 250 mm × 2 rolls, and finished rolls come off on 25, 38, 50 or 76 mm cores. A recessed main control panel keeps operation simple, and all manual operations, including maintenance, can be done by operators without special experience. ULTIMA 250 also slits and rewinds various other film materials.

Advantages of Bronse slitter rewinders
- Accuracy: servo drive technology gives a length repeatability of less than 0.5 m.
- Flexibility: rolls in different cores, lengths and widths from the same machine.
- Practical and user-friendly: starts quickly and can be run by any operator after a couple of hours of training.
- Compact: monoblock design that fits into small areas.
- Built to last: robust design for long service life.
Payback
ULTIMA 250 reduces the need for highly skilled labour and raises output thanks to its slitting and rewinding speed. For distributors, slitting your own rolls from one jumbo width means fewer jumbo sizes in stock and faster answers to customer orders.

How ULTIMA 250 works
- A jumbo roll up to 700 mm wide and Ø480 mm is mounted on its 76 mm core.
- The slitting unit is set to the roll width you need – from 10 rolls of 50 mm to 2 rolls of 250 mm – or left open for full-width rewinding.
- Roll length, core size and speed are set on the recessed control panel.
- The servo drive slits and rewinds at up to 1,200 m/min (1,500 m/min with the double servo motor).
- At the set length the film is cut and the finished rolls are removed – one cycle takes 10.1 s for a 150 m roll.
Choosing slitting widths
Slitting lets one jumbo width supply many products. A 500 mm jumbo, for example, can become two 250 mm rolls for hand wrapping or bundling, or narrow 50–100 mm rolls for banding and small packs. Because the width is set on the machine, a distributor can stock one or two jumbo widths and still accept orders for sizes it does not keep.
Roll formats explained
Most stretch film is sold in three formats, and a rewinder is what turns the first into the other two:
- Jumbo (mother) rolls come straight off the extrusion line, usually on 76 mm cores. They are too large and heavy to wrap pallets with.
- Hand rolls are short, light rolls for manual wrapping, typically on small cores so they can be held on a handle or dispenser.
- Machine rolls are longer, heavier rolls for pallet wrapping machines. Bronse pallet wrappers, for example, take rolls 500 mm wide, up to Ø250 mm and 16 kg on 76 mm cores.
Roll weight is easy to estimate: weight (kg) ≈ width (m) × length (m) × thickness (micron) × 0.92 ÷ 1,000. A 500 mm × 300 m × 17 micron hand roll weighs about 2.3 kg; a 500 mm × 1,500 m × 23 micron machine roll about 16 kg.
What makes a good finished roll
Buyers judge a rewound roll quickly, so it is worth checking samples against these points:
- Straight edges. The film layers should sit flush; a roll whose layers slide sideways (telescoping) is hard to sell and hard to use.
- Consistent length. Every roll sold as 300 m should hold 300 m. Servo-driven length control is what keeps this repeatable.
- Even winding. No wrinkles, trapped air or loose outer layers, so the roll stays round in transport.
- Film properties kept. Rewinding should not over-stretch standard film or damage cling.
Actual running speed depends on the film. Thin or uneven jumbo rolls normally run below the maximum speed, so send us your film data and we will tell you what to expect.
Preparing your site for the ULTIMA 250
Everything you need to plan the installation is in the catalogue values:
- Electricity: 380 V, 3P + N + G, 50/60 Hz, 11 kW installed power (nominal consumption 10 kWh).
- Compressed air: 6–8 bar, 100 Nl/min. Clean, dry air keeps pneumatic parts working longer.
- Floor space: 1910 × 1425 mm footprint, 1990 mm high for the machine itself, plus room to bring in jumbo rolls, take finished rolls away and let the operator move around.
- Floor load: net weight 1,500 kg.
- Jumbo handling: jumbo rolls weigh up to 70 kg, so plan how they reach the machine – a hoist, lifting trolley or crane.
Operation and routine care
ULTIMA 250 starts quickly and can be run by any operator after a couple of hours of training. All manual operations, including maintenance, can be done without special experience.
- Keep rollers and guides free of film residue and dust.
- Check blades and cutting parts regularly and replace them when the cut is no longer clean.
- Drain the compressed-air filter and check the air pressure stays at 6–8 bar.
- Follow the lubrication and inspection intervals in the operating manual.
Machines with remote diagnostics can be checked by our service team over the internet, which shortens the time to a fix.
Frequently asked questions
Why slit instead of buying jumbo rolls in every width?
One jumbo width can supply many roll widths, which reduces stock and lets you accept orders for sizes you do not keep.
Can ULTIMA 250 run without slitting?
Yes – it rewinds at full jumbo width as well as slitting.
Which materials besides stretch film?
ULTIMA 250 is suitable for slitting and rewinding various film materials. Tell us your film and we will confirm.
How many rolls does one cycle produce?
With slitting, one jumbo is cut into 2 to 10 rolls depending on width – from 50 mm × 10 rolls to 250 mm × 2 rolls.
How accurate is the roll length?
Servo drive technology gives a length repeatability of less than 0.5 m.
Does film quality affect speed?
Yes. Thin or uneven film usually runs below the maximum speed. Send us your film data for a realistic figure.
