Die Cutting Three Times Better
As is fitting for a high performance die cutter, we are
constantly improving the Dymatrix 106. Already, it features three
technological innovations that allow folding boxes to be produced
faster, more reliably and at lower costs.
Producing high quality packaging, such as those for
cigarettes, cosmetics or candy, is the strength of the Dymatrix
106. The die cutter has full mastery of an extensive repertoire of
various folding box types and materials, from thin paper to
corrugated board and plastic. It can do all this and still be
profitable. "Especially in the case of industrial production,
packaging must look perfect and needs to be produced quickly,
reliably and flexibly. That is why we have fine-tuned three
important points: we have further improved the alignment and
separation of the sheets and also made it easier to implement tools
from other brands," explains Hakim Arbaou, Production Manager
Postpress at Heidelberg.
Faster: Sheet Alignment
During die cutting it is particularly important to
transport the sheets straight-edged and in a stabile horizontal
position to the individual stations. Only then can an absolutely
accurate register and maximum production speed be achieved in die
cutting. But usually things look quite different: hardly any piles
of sheets make it from the printing press to the die cutter's
feeder with completely straight edges. A lot of operators simply do
not have the time to align the pile of sheets exactly. This is no
problem for the Dymatrix 106.
Now sheet alignment does not just take place mechanically
with front and side guides, but with a uniquely developed automatic
feed system called DySet. At its core is an optical sheet sensor.
After a pile has reached the feeder and the sheets have been
separated on the belt table, the front guides in the feeder
register their alignment. The optical sensor then surveys the side
edges of the sheets. In case of a false position, the side position
of the sheets is corrected before they are handed over to the
gripper bars. These then transport the sheets to the next stations
on the machine. "Thanks to DySet, the number of waste
sheets in the feeder, the so-called stoppers, can be reduced by up
to 70 percent," reports Arbaou. In addition to the higher
productivity, manufacturers of folding boxes and die cutters profit
from increased register accuracy. This enables them to cut even
difficult layouts reliably.
More Reliable: Sheet Separation
Not only the alignment, but also the separation and
transport of the sheets, is now more reliable and simpler. This is
due to the new belt table and feeder of Dymatrix 106. "We
modified all components with the goal of making the separation and
guidance of the sheets in the feeder absolutely reliable,"
says Arbaou. Fewer but therefore wider belts, a newly designed
suction head as well as an optimized inclination angle of the sheet
ramp are just a few of the improvements.
Thanks to these innovations, the Dymatrix 106 processes a
wide range of materials reliably and without the need to convert
parts of the machine - from very thin paper (80 grams per
square meter) up to solid board (up to 2,000 grams per square
meter). "Businesses don't have to add any additional
equipment like rolls or brushes for changes in material, for
example from paper to solid board and vice versa. The sheets are
also separated reliably at high production speeds," emphasizes
Flexible and More Cost-Effective: Using Tools from Other Brands
Businesses which use die cutters from various
manufacturers can assign orders more flexibly in the future. This
is because cutting tools from other brands specific to a particular
order can be used on the Dymatrix 106. "Particularly for
businesses with high cutting workloads, this is an enormous
advantage. It gives them the necessary leeway to process
short-notice jobs on time. First-time orders and recurring orders
no longer have to be carried out on the same die cutter,"
explains Arbaou. In addition, Dymatrix businesses do not have to
acquire new cutting tools. A variety of order-specific cutting
tools can be used for various orders because they can be used
regardless of the printed design. This is true for packaging for
hair dye, for example. Here it does not matter if hair is blond,
brown or black - the folding box is the same.
