Goss is to launch a new high-performance version of its Community-derived Magnum one-around single-width press with an H-type unit and a top speed of 70,000 cph.
The Magnum HFS delivers the pagination flexibility of a one-around press with productivity associated with two-around designs… an argument used in favour of 4x1 presses.
Key to the development is a new H-frame configuration which improves plating access and hence job changeover, and an upgrade of printing cylinders to triple-race bearings, through bearers and narrow gap, reel-rod lock-ups. Web tension is optimised with synchronised shaftless drives for infeed and outfeed as well as the printing towers.
Two jaw folder options are available – J1:3:3 suitable for production speeds up to 50,000 copies per hour and J2:3:3 for speeds up to 70,000 cph.
Goss says its development team drew from its entire portfolio of newspaper and semicommercial presses for the new design.
The press has centralised control of ink keys, spray bars and registration, with three-form inking, and automated controls with remote inking and presetting are among options.
Goss sees it in a variety of applications including heatset, coldset, UV and hybrid configurations for newspapers, semicommercial and combination products.
The original Magnum was a development of the Community – launched in 1962 when the company was still MGD (for Miehle Goss Dexter) – later to feature stacked mono units in the original ‘four high’ towers. The design also spawned an aftermarket business in cutting the integral reelstands from mono units.
A static tower will be on display at DRUPA along with a tower from the compact Colorliner CPS being built for DC Thomson in Scotland.
The new Magnum HFS is a far cry from early Community units, 40,000 have now been sold around the world. Production moved to at Goss’s plant in Shanghai, China – developed as a joint venture with the company which now owns it outright – a decade ago.
From the early production speeds of 12,000-14,000 cph, increases have come from a variety of sources, notably folder design, the SC using the Suburban folder, and the SSC increasing print image with a smaller blanket lock-up.
Goss now quotes speeds of up to 35,000 cph for the Community, with products up to 12 and 16 webs possible with N40 and 1:3:3 folders.
