Controls gatefold, gluing and timed perforation functions
At Print 2001 in Chicago, Heidelberger Druckmaschinen AG
(Heidelberg) unveils the new ACC 2.4 digital controller for
Heidelberg's folders (ACC = Accessory Controller). It controls
the peripheral devices used for gatefolding, gluing and timed
perforations. The ACC 2.4 features tremendous functional
flexibility and ease of operation. With the low investment costs,
users gain a considerable financial advantage over conventional
controllers that are designed for just one application. The inline
gatefolding, gluing and timed perforation workflows significantly
boost the practical applications of the Heidelberg Stahlfolder and
other makes of folders, and also deliver attractive end products
with enhanced product quality.
The ACC 2.4 can simultaneously control two gatefold buckle
plates or two spot gluing guns. Other options include two EAP heads
(EAP = Single Section Perforation), one gatefold buckle plate and
one spot gluing gun or one gatefold buckle plate and one EAP head.
Gatefolding now a breeze at 15,000 cycles per hour
Independent of the folding speed, the device also precisely
controls the switching times for the new FFP gatefold buckle plate
from Heidelberg. Continuous operation at 15,000 cycles per hour is
easy, since the design no longer includes any solenoid that can
heat up. Precision control of the deflecting profile allows very
small flap gaps of between just 0.5 and 1 mm, depending on the
thickness of the paper. Because double folding is minimized, paper
thicknesses between 80 and 150 gsm can now be processed in
multi-up.
Gluing in the folder as an additional service
Gluing apparatus increases the added value of the folder,
enables penetration of other market segments and improves
processing of intermediate products. The ACC 2.4 supports
interrupted glue lines, variable spot gaps and different spot
sizes. Auxiliary gluing is also possible to give the best possible
finishing effects for envelopes with flaps on gatherer-stitchers
and adhesive binders. With the new in-plate cold glue guns, the
folding rollers no longer need to be segmented.
Timed perforations for attractive products
Timed perforations are often used in cases where
postcards are to be removed from a larger brochure by tearing them
along an angled perforation. The ACC 2.4 controls the EAP heads
needed for this, making the production of these otherwise complex
yet particularly attractive products possible. Two EAP heads can be
used at the same time, and controlled independently of each other.
Each EAP head can carry out up to four timed perforations per
sheet.
