The new cantilever divert unit for T48A book presses is being launched at drupa. With full pre-setting facilities as standard, this unit saves time and manpower in threading up, and is a logical development in Timsons’ programme of increasing book press productivity by reducing down time to release additional capacity.

The parent web can be slit into a number of ribbons – normally three, four or five; the ribbons can then be assembled in any sequence for the folder.

Two variations of flopping (turning over) ribbons are available – a fixed format selected by the printer when the press is ordered; or variable format allowing complete freedom to put any ribbon in any position, flopped or unflopped.

The unit also automates the unavoidable, intricate and time consuming task of repositioning half ribbons between two full ribbons for binding.

In high-pressure, high labour cost environments, with presses working round the clock, the cantilever divert dramatically reduces web threading time, and generates an attractive payback on investment.

Makeready techniques
Inbuilt make ready techniques that maximise profitability and productivity on T48A book presses will be highlighted.

The ZMR option delivers genuine zero make ready on one-colour books through twin over-and-under printing units. While one unit prints at speeds up to 450m/min., the press man changes plates on the other unit.

As soon as the active unit finishes printing the last signature, the second unit – already accelerated and synchronised at web speed – immediately begins printing. There is a minimum of paper waste, and lost production time is measured in seconds.

The standard T48A press incorporates the Timsons Simultaneous Plate Changing System, which allows the operation to be completed in less than three minutes.

All Timsons T48A book presses are designed to optimise performance. Print cylinder circumference and web width are chosen to minimise trim waste and maximise the number of pages in the signature. Substrates from 28gsm bible to high bulk or coated stocks can be used.

T-Flex 600 flexo press
At drupa Timsons will demonstrate the quick-change capability that maximises profitability in high-quality, short-run printing of packaging material including film, paper or board. Outstanding heat management throughout the press means that the T-Flex 600 can meet the growing demand for shrink sleeves.

T-Flex 600 print cylinders can be changed easily without the use of tools – one man can change eight cylinders in around 15 minutes using the Timson ‘lift-and-slide’ system. The press is usually installed with up to 10 units, printing in eight colours with options for laying down a primer, varnishing and laminating.

The press is based around a newly developed and sophisticated enclosed chamber system. Accurate temperature control optimises ink transfer and maximises quality performance on text, fine half-tones and heavy solids.

Capable of printing 150-line screen at speeds up to 260m/min, the press has a 600m-web width and an infinitely variable repeat range from 300 to 600mm. It can be used with sleeves or conventional print cylinders, and print with environmentally friendly inks – water based or free radical and cationic UV inks, including the latest generation of low/no odour UV inks.

UV versions can be fitted with the latest Hönle UV dryers to enable printing on to heat sensitive films.
