At IPEX 2010, Heidelberger Druckmaschinen AG (Heidelberg) will be
launching its new Stahlfolder KH 66 combi folder with automatic
cross-fold unit. The series of fully automated combi folders thus
now includes a model with a working width of 66 cm (25.98 in) and
is also available for processing classic 16-page print sheets with
a flat sheet format of 63 x 88 cm (24.80 x 34.65 in). The technical
configuration is the same as that of the Stahlfolder KH 82 unveiled
at drupa 2008, which is now being used successfully in production
operations the world over. Just like the KH 82, the KH 66 now runs
at up to 230 meters per minute - even in cross-fold operation. The
maximum speed has been increased to as high as 30,000 cycles per
hour. Depending on the level of automation selected, the setup time
of the cross-fold unit is cut by up to 80 percent compared to the
non-automated KH 66 model. The new KH 66 too can be networked using
the Web-based Remote Service software solution, which boosts
machine availability. What's more, Prinect Postpress Manager
enables the machine to be integrated into the workflow for
transparent production processes.
The Stahlfolder KH 66 KTL configuration with a buckle plate after
the first folding knife boosts the number of folding options. The
optional pneumatically controlled turn buckle plate enables sheets
to be turned reliably in the machine, for example to create a
classic newspaper fold. This makes the KTL a true all-rounder.
Focus on customer benefits - using automation to cut makeready
The key element of the new combi folder is the new
servo-driven folding knife. It enables the maximum speed to be
increased to 30,000 cycles per hour. The servo drive allows the
knife speed to be regulated independently of the main drive. The
knife can also be moved manually using the jog wheel (electronic
handwheel) to check the sheet alignment, for example. All knife
settings, such as the height and incline, can be stored and
reproduced for repeat jobs.
This increased level of automation, tailored consistently to
maximize customer benefits, has also been implemented in the new
cross-fold unit of the KH 66 and cuts makeready times in this unit
by up to 80 percent. The operator can load the paper while the
cross-fold unit adjusts automatically. New, pneumatically raised
front edge rollers pull the incoming sheet right up against the
sheet stop and prevent the sheet from rebounding.
Access to the slitter shafts in the 1st and 2nd cross-fold
units has been improved considerably on the new Stahlfolder KH 66
through the introduction of slitter shaft carriages that can be
moved laterally. The slitter shafts are thus freely accessible and
extremely easy to operate. This speeds up the process of completely
changing the slitter shafts by 20 percent.
Particular importance was placed on the machine's operating
concept. Control elements and visualization functions can be
operated and viewed from three sides thanks to a tilting control
console with touchscreen on the cross-fold unit. On-site operation
where it is needed enables each setting to be checked visually as
it happens. The workload is eased by means of intuitive touchscreen
operation supported by graphics and a very user-friendly jog wheel.
Waste sheets, stemming primarily from the setup procedure and
jams, are a significant cost factor. The pneumatically raised sheet
stop can eject a misfolded sheet at full production speed, thus
preventing jams in the cross-fold unit.

Heidelberg at IPEX 2010:
reflect the extensive portfolio of
state-of-the-art technologies and services from Heidelberg for the
economical and environmentally friendly production of print
products. At the trade show, the company will be providing
practical demonstrations to highlight how media service providers,
print shops, and postpress specialists can act on current market
trends and adapt their portfolios accordingly. Heidelberg will be
demonstrating how to optimize business and production processes
across the entire value added chain of sheetfed offset printing,
while also minimizing their environmental impact.
The numerous practical demonstrations will enable visitors to
the event to find out how they can achieve economic success with
short-run high-end print applications, stand out from the crowd
with creative print applications, and make the Internet an integral
part of their business strategy.
