The product has been developed in response to market demands for a photobook finishing system with high cut quality and productivity.
Managing director Stuart Murphy said the product could also be manufactured in other sizes that would make it suitable for B1.
He said: "PhotoSlit is a good example of how we can respond quickly to create a bespoke finishing solution.
"Very often we design and build equipment in situations where other manufacturers will not even consider trying to find an answer."
It has a gutter size as small as 1.6 mm, and can significantly reduce waste and produce more pages per printed sheet than other photobook systems on the market.
It can handle up to 8,000 SRA3 sheets an hour with a page size range between A6 and A3 although Rollem added it could make a system capable of handling sheets down to 75 x 30mm.
The standard SRA3 PhotoSlit product costs £55,000 and this includes all that is needed for most photobook pages in an in-line environment.
Elsewhere, Rollem has also signed up Lyon-based Ollagnier as its distributor in France.
UK manufacturer Rollem develops bespoke finishing systems for the sheet-fed commercial, packaging, digital and specialist print markets.
