When filling building materials,
minerals, chemical products as
well as food and feeding stuff, the
ROTOSEAL System developed by
HAVER & BOECKER will surely
convince you when it comes to
operation and economics. The particularly
clean filling and exact
weighing with a filling capacity of
up to 3000 bags/hr. are the remarkable
characteristics of this system’s
continuous development.
The especially remarkable
features are:
Smooth handling of filled bags in upright position
• exact feeding
• complete seal between the bag
valve and the filling pipe during
filling
• exact positioning of the filled bag
before closing off
• optimally designed bag opening
with minimum possible valve
extension
• ultrasonic bag sealing before
discharge of the filled bag
(for the highest possible sealing
rate)
•cost savings from reduced plant
operating costs, reduced filter
system sizes, minimized energy
consumption, improved work
conditions and longer lifetimes
of downstream equipment
For discharging clean bundles,
the ROTOSEAL PACKER
requires no downstream bag
cleaning systems or dust removal
devices.

Getting optimum filling
results with free-flowing,
bulk material is the
objective of our continuous
development of the
HAVER impeller filling
systems.
The advantages for
the user:
•improved product
handling and protection
of the bags via short
filling spouts and
reduced aeration
• airtight seal of bag
valves during filling by
using inflatable filling
spouts
• absolute cleanliness of
bags and optimized bag
closing results are
achieved by preventing
product accumulation
at the bag valve
• use of conventional,
self-closing bag valves
is possible as well
• automatic, stepless
bag length adjustment
is integrated
And another special
feature:
The HAVER MEC III
weigher electronics
controls the weigher
functions, filling spout
functions and
bag closing system
functions.

The well proven, air type
filling sytem used in the
building materials,
chemical, feeding stuff
and food industry
together with
ROTOSEAL technology
make an ideal
combination.
The advantages that
emerge are:
•higher filling speeds
• optimized product-air
mixture preparation
using minimized air
quantities (for smooth
product filling and
minimized loading on
bags)
• hermetic seal between
bag valve and filling
pipe during filling by
using inflatable sleeves
• absolutely clean bags
and optimum closing
result by preventing the
product from accumulating
in the valve area
• consistent high quality
with blended products
(≤ 16 mm grain size)
• low operating cost
• exact positioning of
filling spouts by using
servo-drives
• automatic stepless bag
length adjustment is
integrated

functions, filling spout
functions and

HAVER ultrasonic bag closing system on the filling spout
The optimized bag closing
system using the HAVER
ultrasonic process prevents
unwanted material leakage
from the bag valve,
assures cleanly filled bags
and subsequently improves
storage and handling of
filled bags.
After filling, the valve
bag is moved away in
the standing position.
The ultrasonic closing
head then pneumatically
swivels downward and
welds the plastic or plastic
coated paper valve
shut.
Special advantages
•secure closure, even
when the valves are
affected by the material
inside
• self-cleaning effect of
the weld zone by the
ultrasonic system
• short cycle times – high
hourly production rates
• parallelogram transfer
system for moving the
filled bag away from
the filling spout
• all standard valve sizes
can be closed
• heating occurs only in
the weld zone
• valve position sensors
for activating the ultrasonic
generator
• reliable, low maintenance
technology

HAVER UNISEAL
A Stationary Bag Closing Unit for ROTO-PACKERS
The HAVER UNISEAL closing
system is an alternative valve
closing device and lends itself
to applications where existing
ROTO-PACKERS cannot be
converted to the ROTOSEAL
system or where the individual
application conditions and
requirements allow the system
to be used.
For closing valve bags with a
short external valve with sealable
inner coating (e. g. PE) according
to the ultrasonic sealing system.
System details and functional
sequence:
• As with the ROTOSEAL, the bag
valve is sealed by ultrasound
before discharging the filled bag.
•A stationary ultrasonic sealing
device is located closely
upstream from the bag discharge
belt, i. e. in the area where the
bag filling process on the ROTO-
PACKER is usually finished. The
drive ensures automatic adaptation
to the ROTO-PACKER speed.
•Before reaching the closing position,
the filled bag is gently
pushed off the filling tube in an
upright standing position so that
it is exactly aligned on the tipping
saddle for closing.
• The sealing process is carried out
continuously in conjunction with
the revolving ROTO-PACKER.
The external valve is mechanically
positioned for the optimal
seal.
• Afterwards the clean and sealed
bag is discharged onto the transport
belt.

• The bag valve of the UNISEAL
is also hermetically sealed during
the filling process by inflatable
filling tubes to ensure absolute
cleanliness and optimal sealing
result by avoiding accumulation
of product within the valve area.
•Different bag lengths are automatically
adjusted at the ROTO-
PACKER.
• Useable for HAVER ROTO-
PACKERS with 3 to 12 filling
spouts.
• An output of up to 3,000
bags/hour is achieved.

HAVER Weigher Electronics MEC III
MEC III control terminal
The MEC III results from
the continuous development
of the 6th generation
of HAVER electronic
weighers.
The MEC III and OIML
is a PTB approved electronic
measurement
device that can be calibrated
and has a resolution
of 6000 increments.
This terminal has a contrast
graphic display for
showing all operational situations
such as:
•weight values
• weigher settings
• dialogs
•status information
• error messages
The simple and well-structured
operational
sequences are done
through menus or via function
keys.
For the appropriate setting
of the ROTOSEAL
PACKER, there are aids
for analyzing the filling
process with respect to
the filling time and the
mass flow rate.
Technical specifications
of weigher features:
• gross / net
• taring / zero setting
• dosing time regulator
•dribble feed regulator
• dynamic filling
cut-off point
• filling by weight or
by volume
• tolerance evaluation
• adjustable weigher
signal damping
• bag breakage detection
• regulated filling vessel
aeration as a function
of
mass flow rate
• product memory for 99
sorts
• weight correction by an
end-of-line check
weigher is possible

HAVER valve bag applicator systems
The ROTOSEAL System
can be automated simply
and comfortably by
using the time tested
HAVER RADIMAT bag
applicator technology.
The application speed is
automatically adjusted to
the speeds of the bag filling
and bag closing systems
– without special
operator interference.
A servo-driven applicator
unit ensures reliable and
exact bag placement over
the long term.
Bundle system:
For frequent changes of
bag sorts, a bundle system
with direct feeding from a
horizontal empty bag
bundle magazine is the
best choice.
HAVER RADIMAT bundle system
Reel magazine:
For high speed systems,
the advantages of a reel
magazine in simple or
double version come into
play. A significant
time-saving factor can
be achieved by using a bag
reel magazine instead
of a bundle magazine,
especially for production
outputs > 2000 bags/hr.
