krones Contiform Bloc
Stretch blow moulder and filler in an effective combination
Bringing together what belongs together
Stretch blow moulder and filler in an
effective team. And that is the reason
why we have perfected the popular
combination of both machines even
further in a single block in the form of
the Contiform Bloc. With a seamless
drive concept, finely tuned transfer
interfaces for every production program and precisely operating processes in stop situations, you can count
on getting the very most out of your
PET bottle line.
Compact, economical and flexible
– that is the Contiform Bloc for all
applications. Because it is able, of
course, to process every type of product supplied in non-returnable PET
containers available on the market
and also enables everything from
aseptic filling processes to hot and
cold bottling as required for the processing of liquid products in PET bottles. What is clear is that when it
comes to container design and volume, you have absolute freedom
because the Contiform Bloc really
demonstrates its strengths in flexible
production processes. And your staff
can therefore make the most of their
potential, as the compact line allows
great freedom for efficient planning.

Method of operation
The Contiform Bloc combines the
Contiform stretch blow moulder
in direct modular design with the
Modulfill filler – including capper.
The individual machines can be disengaged from one another quickly in
stop situations with the help of the
central controller and the servo drive
concept. This cuts out long start-up
phases when restarting. Integrated
inspection and rejection units ensure
that the production flow is always
monitored immediately at critical
points.
Applications
■■ Production of non-returnable PET
containers with volumes of up to
3 litres
■■ Filling concepts for water, soft
drinks, milk and mixed milk drinks,
fruit juices, teas, cooking oil, beer,
wine and ketchup
■■ Aseptic production processes
(H2O2, PAA), hot and cold filling
processes
■■ Processing of round and lightweight bottles

■■ High performance with the new
blowing station
With a station output of 2,250 containers per hour, a highly efficient
stretch blow moulder is integrated
in the block concept.
■■ Low compressed air consumption
Thanks to the electromagnetic
stretching system, further minimisation of the dead space volume and the new “Air Wizard Plus”
compressed air recycling system,
compressed air consumption is
reduced to a very low level.
■■ Energy-efficient machine concept
Further improvements to the infrared oven result in significantly
reduced energy consumption.

continues operating even in the
event of faulty caps
■■ Hygienic design with reduced surfaces in seamless self-draining

■■ Controlled block conditions
■■ Short paths for the bottles
A partition between the stretch
blow moulder and the filler prevents any impairments to machine
workflows from media or air.
■■ Transfer of hygienic bottles
Since the bottles are transferred
directly to the filler, they can be
processed immediately after the
stretch blowing process without
any risk of recontamination from
the surroundings.
■■ Sterile filtered blowing air
The stretch blow moulder can have
sterile filters fitted in the compressed air supply as an option.
The blowing air will then be absolutely clean in hygienic terms.

After the stretch blowing process
the bottles are transferred directly to the enclosed transfer starwheels of the filler – with only
short conveyor sections.
■■ Controlled bottle guides
The continuous guidance of the
containers is monitored throughout on the neck ring. This eliminates scuffing and other types of
damage.
■■ Quick format changes
With the seamless transfer concept for containers on multifunctional clamping starwheels and
the controlled clamps, no adjustment work is required on the
guide units when the format is
changed.

Precise monitoring devices specifically modified for the machine
concept enable faulty preforms,
bottles, caps or labelled bottles to
be rejected.
■■ Integration the control panel
The display for a possible overload
of the drive system and the controlled disengaging of block machines ensure that safe and reliable
operation within system limits is
maintained.

Your advantages
■■ Efficient and profitable
The quick change-over whenever the bottles or products are
changed and the effective strategy
for disengaging individual block
elements in stop situations enables you to achieve maximum performance for your entire production program.
■■ Compact layout
Combined machine concepts save
space. The Contiform Bloc offers all
the functions without buffer and
conveyor sections and is therefore
the ideal solution for many confined spaces.

■■ Convenient for the operator
The Contiform Bloc offers a good
overview, short paths and a standardised operating concept. It also
requires little work for changeovers and has an optimised maintenance program thanks to the use
of servo technology.
■■ High standard of hygiene
Having only a few interfaces and
conveyor sections are key factors in achieving a high degree of
cleanliness for the bottle material.
The direct transfer of the bottles
from the stretch blow moulder to
the filler and capper prevents dirt
being brought in.
■■ Gentle on the bottle
Neck handling is the optimum
solution for PET bottles. And a low
number of transfer stations. Combine these features in the
Contiform Bloc and top bottle
quality is assured.
