Since its introduction at Drupa 2000 Heidelberg's Speedmaster CD 74
has become the clear market leader in the high performance A2
sector. Continued productivity enhancements will ensure that the CD
74 continues to set the pace in this high-speed, high-quality
sector.
Now with over 200 units installed in Australia and New
Zealand, the CD 74 has taken A2 printing to new production levels.
With a comprehensive range of presses from the traditional four
colour to the industries first five over five long perfector with
coating on both sides there really is something for everyone with
the CD 74.
To cement its place as the market leader in A2 press sales,
the CD 74 has taken another leap forward in production output
through the introduction of 18,000sph printing. To support such a
production speed, a host of industry-first features have been added
to the press to ensure that increased output can be achieved on a
daily basis.
As all printers will know, the secret to achieving higher
production speed is in the feeding and delivery of the sheet. With
this in mind, the CD 74 now comes standard with a new feeder head
and new sheet brake also two optional unique features to ensure
stable production.
Preset Feeder head. (Standard)
By entering the sheet size and stock thickness into the
CP2000 console, the CD 74 aligns the feed header and draws on a
database of stored air settings in the CP2000 console to set the
required air blast and suction air for the lifters. This automated
feature therefore removes the need for operators to 'fiddle'
searching for the required settings and thus reduces the
possibility of human error to an almost zero.
Automatic Pile Lifting Control. (Optional)
To ensure the feeder head is always at the optimal height for
sheet transportation to the feed table, sensors at the
front edge of the pile constantly measure the pile height in
relation to the feeder head. If height varies due to uneven stacks
the CD 74 automatically lifts or lowers the feeder head, keeping
the stack and feeder head at optimal height for high speed
production.
New Sheet Brake/Dynamic Sheet Brake
The ability to slow sheets coming through the press from
18,000sph and stack them neatly and mark free in the delivery, or
to handle difficult stocks is a challenge.
The CD 74 is now fitted with three dual remote controlled
sheets brakes, giving a total of six sheet brakes (standard). The
positioning of the brakes is controlled via the CP2000 console.
When running without a centre gutter the centre brake can be
removed and the outer brakes angled outwards tensioning the sheet
to ensure no marking happens on the underside and production speeds
can be maintained.
Optionally the CD 74 can be fitted with the new Dynamic Sheet
Brake, where each sheet is picked up by the sheet brake at 95% of
the delivery speed then individually slowed down and delivered to
the pile. The brake repeats this for every sheet ensuring mark
free, clean stacks.
With these further enhancements, the CD74 is sure to continue
its place as the market leader for high performance A2 printers.
