Heat Is Optional. Pressure Is Not.
Most laminating problems are not adhesive problems. They are pressure problems. A pouch laminator runs hot rollers over a sealed sheet and hopes the adhesive behaves, which is why warped posters, silvered photo prints and heat sensitive inks come out of the machine looking worse than they went in. A cold roll laminator takes the other route: no heat at all, just two rollers pressing adhesive film onto the sheet under controlled pressure, which is the method that keeps a pigment print's colour and a poster's dimensional stability intact.
The LBS650 is built around a 648 millimetre throat, which takes A3 with room to spare and handles A3+ and 25 inch wide stock without folding the edge. Laminating thickness adjusts to 35 millimetres, so a mount board, a foam core panel or a doubled sheet can pass through instead of jamming at the entrance. The rollers are 65 millimetres in diameter with an 8 millimetre wall, and roller diameter is what determines how long the film stays in contact with the sheet at a given crank speed, which is the real reason large roller machines produce a smoother result than a desktop pouch unit.
It is hand cranked, so there is no motor to stall and no thermal fuse to replace. That also makes it the machine you can run in a room with no extractor, next to a wide format printer, without waiting for a warm up cycle. The current production build ships with a plastic handle rather than the earlier metal type, and the A3 working width is the practical ceiling for poster, photo and document work rather than signage.
The print leaves the printer finished. This is the machine that keeps it that way.
Why Cold Roll
- No Heat Cycle — Nothing to warm up and no heat damage to pigment prints
- 648 mm Throat — A3, A3+ and 25 inch stock through the rollers in one pass
- 35 mm Adjustable Thickness — Mount board and foam core pass without jamming
- 65 mm Rollers — Larger diameter holds film contact longer for a smoother finish
- 8 mm Roller Wall — Thicker wall resists deflection across a wide throat
- Manual Crank Drive — No motor to stall, no thermal fuse to fail
- Bench Footprint — Sits beside a printer rather than needing its own table
- Cold Adhesive Compatible — Works with cold laminating film and mounting adhesive

Who Runs One
A print shop with a wide format printer uses it to finish posters and photo panels without risking ink shift on heat sensitive media. A photography studio uses it for exhibition prints and album pages, where a cold process keeps the paper flat and the blacks from bronzing. A school or university print room uses it for document covers and display boards, because a hand cranked machine has no warm up time and no element to burn out between terms. A sign shop uses it on foam core mounted panels and small rigid displays that would jam a heated pouch laminator at the entrance rollers.
Sizing and Use Questions
Q: Does it use heat at all?
A: No. The process is pressure only, which is why it suits pigment inks, photo papers and heat sensitive media. Use cold laminating film or cold mounting adhesive, not thermal pouches.
Q: Can it laminate both sides?
A: Yes, film can be applied to one or both faces of a sheet in separate passes. Let the first side settle before running the second, and keep the sheet flat between passes.
Q: How thick a board will it take?
A: Up to 35 millimetres of laminating thickness, adjustable. That covers mount board and most foam core panels, which is the practical limit of a bench machine rather than an industrial one.
Q: Is the crank hard to turn on wide sheets?
A: It takes steady effort on a full 648 millimetre pass, which is normal for a manual machine. Feed the sheet square and keep the crank speed even, because inconsistent speed is what produces bubbles.
Q: What about bubbles and silvering?
A: Almost always feed or pressure related. Clean rollers, feed the sheet square, keep even crank speed and make sure the film is not being stretched as it goes in.
Q: Is this suitable for production volumes?
A: It is a bench machine for short runs, one off prints and mounting work. Continuous high volume finishing needs a motorised roll laminator, which is a different class of equipment.
