A hArd-hitting - Plantin

This makes it possible to produce longer runs much faster and, because
the covers are loaded automatically, the operator can concentrate
on the manual process of inserting the blocks. One operator can
insert around 800 to 1,000 blocks an hour.
Short Setup Time. Even with longer runs, the Eurobind 1300 PUR
is more than capable of competing with large adhesive binders. For
example, Color Gruppe was asked to produce 12,000 copies of a brochure
with a pocket on the outside back cover page. This pocket had
to be filled manually. “A large adhesive binder runs so quickly that
it would have been necessary to stack the bound brochures on pallets
before being able to package them,” explains Wagstyl. “Thanks
to the slower speed of the Eurobind, however, we were able to set up
packaging tables to package the brochures straight after binding,”
he adds. The customer was quite satisfied.
The faster setup time of the Eurobind 1300 PUR Line is particularly
useful for shorter runs. While it takes around 10 minutes to
set up this line together with the Eurotrim 1000 three-knife trimmer,
The PUR nozzle application system of the Eurobind 1300 PUR is controlled by a gear
pump. As a result, it applies exactly the same amount of adhesive to each block –
irrespective of viscosity, temperature or pressure (below). View of the lift-type delivery

a larger adhesive binder takes around 30 to 60 minutes and several
operators to set up. There are, of course, also jobs where the time
factor is of little importance. “We have even used the Eurobind 1300
PUR for a run of 60,000 copies. This stretched over several weeks,
with us returning to the job whenever we had spare machine capacity,”
recalls Wagstyl.
Does What it Promises – And Then Some. Color Gruppe mainly
uses the Eurobind 1300 PUR to produce traditional soft-cover brochures
with a four or six-sided cover – from the A6 to slightly smaller
than the A3 format. This means the print shop sometimes operates
significantly beyond the upper and lower limits specified by
Heidelberg. Normally, the block should be at least 0.08 inches
(2 mm) thick, but the Munich print shop has been known to produce
12-page brochures with a spine thickness of just 0.04 inches (0.9 mm).
“Some customers simply refuse to accept stapled products, so we
operate at the limits of what is technically feasible,” says Wagstyl.
This, however, requires a great deal of experience and a lot of fiddling.
Such a thin spine cannot be produced at the touch of a button
– even with a large adhesive binder. “Applying the adhesive extremely
accurately is the key,” explains Groß. “The display enables
the operator to control the amount required very precisely,”
he adds. The adhesive application head can also be adapted to
the required block contour. This feature is unique to Heidelberg
and essential for customers who work with a very wide range
of materials.
In addition to nozzle application, the preparation of sheet
edges at the spine is also vital for ensuring high-quality adhesive
binding. The spine preparation station on the Eurobind
1300 PUR consists of a combination tool with dust cutters,
roughening teeth, notching knives and a ring brush – all of
them individually adjustable. This ensures ideal preparation
of the block spine for gluing.
The high-quality spine preparation – unique in this format
class – and the uniform application of adhesive achieved by
the polyurethane nozzle application system are an unbeatable
combination in Wagstyl’s opinion. “They enable us to satisfy
our customers’ exacting quality requirements – reliably and
flexibly,” he concludes. n
