Bonelli T52/4/4

The T52/4/4 is Bonelli's twin-unit pocket folder, four parallel folds in each of two units, rotary-fed with a counter, on 52 by 80 centimetre sheets.

Italian buckle folding in its classic form: eight pockets of capacity for bookwork and commercial folding.

Each job you run comes with its own specific problems, and more often than not the culprit is found on the tooling shafts. The standard finishing tools supplied with your machine aren’t accurate, versatile or delicate enough for the results you and your customers expect. At Technifold we design and build bespoke, retro-fit premium finishing tools to solve both common and complex finishing problems.

Your T52/4/4, finished properly.

What we solve

Problems we eliminate on the T52/4/4

Eliminate fibre crackingCracked colour on the fold, on digital, coated or cross-grain stock. The steel score that causes it, and what replaces it in minutes.See how we eliminate it →

True micro-perforationRagged bursts, paper dust, stacks that will not lie flat. The coarse perf wheel that causes it, and the blade that replaces it in minutes.See how we eliminate it →

Guillotine-quality cuttingFuzzy, dusty edges and a second pass at the guillotine. The crush-cut slitters that cause it, and the scissor-action tool that replaces them in minutes.See how we eliminate it →

Section scores that holdSections that spring open, gusset at the head and fight the stitcher. The barely-there steel score that causes it, and the deep, defined score that replaces it.See how we eliminate it →

Pharma leaflet scoringTorn scores and wrinkled folds on thin, highly-folded leaflet work. The abrasive steel score that causes it, and the six-setting pharma score that replaces it.See how we eliminate it →

Book cover creasingSpine and hinge creases in one pass, in register, without cracking. The cover work you send out, done on the folder you already run.See how we eliminate it →

Close-proximity finishingCrease beside cut, crease beside perf, cut beside perf, or doubles of any of them. One housing, six set-ups, no letterpress bill.See how we eliminate it →

Crease with perfs both sidesThe perf-crease-perf pattern for stubs and tear-offs, packed into millimetres, in one pass. The specialist tool for work that otherwise goes to letterpress.See how we eliminate it →

Custom & OEM toolingA part that is obsolete, impossible to source, or never existed. If it is a wheel, a blade, a rib or a holder that touches paper or board, we can probably make it.See how we eliminate it →
