Reliable adhesive application at top speed
Peterstaler Mineralquellen invest in a new filling line for glass bottles. For the tamper-evident seal required
by German law, it uses a shoulder label with a safety seal strap. Innovative adhesive application technology
from Robatech is used in the KHS Innoket Neo labeling machine. A SpeedStar Diamond application head
applies the hot melt adhesive for the safety seal reliably and cleanly to the bottle closure.
Bad Peterstal in the Black Forest is known for its mineral
springs first discovered in the first half of the 19th century.
Peterstaler Mineralquellen GmbH was officially founded
in 1926, and expanded in 1941 to a second production
facility in nearby Bad Rippoldsau. The company bottles
not only mineral water, but also lemonades, spritzers, and
sports drinks, and is still family-owned today. The bever-
took force in Germany on January 1, 2003 initially sup-
pressed the market for non-returnable glass bottles for
several years. Over the last three or four years, however,
there has been a kind of renaissance for mineral water in
glass bottles. The general trend towards healthy eating
and regional products has given glass new life in the bev-
erage packaging arena. Classical mineral water brands
have seen stable growth in this product segment again
for the past few years. So at the beginning of 2015, man-
agement at Peterstaler made the momentous decision to
purchase a new glass filling line to be installed at the Bad
Peterstal plant. At the same time, they invested in a new
logistics center.
The headquarters of Peterstaler Mineralquellen in Bad Peterstal
ages are filled into glass or PET bottles of different sizes,
both disposable and returnable containers. In all, about
80 different products make up the product line of Peter-
staler Mineralquellen today.

Different glass containers
A complete rebuilding of the glass filling lines was in-
cluded in the plan, since the existing equipment at the
Bad Rippoldsau plant was showing obvious signs of
age. Various engineering companies were evaluated,
and Peterstaler Mineralquellen decided on KHS has a
complete provider capable of delivering the entire system
from a single source, including the conveyor belts and
labeler. „We wanted to purchase another system with a
capacity of 30,000 bottles per hour. The system would
have to consume significantly less power, be operated by
no more than two people, and fit into the close quarters of
600 square meters on the third floor. Short tooling times
were extremely important for us, because on average the
system has to be changed over to a different format every
three to four days,“ said technical lead Wolfgang Sum,
summarizing the requirements.
Peterstaler Mineralquellen decided on a system manufac-
tured by Dortmund-based KHS GmbH. KHS installed its
modular „Innoket Neo“ as the labeling machine. Machines
in this series can handle self-adhesive, cold glue, roll-fed,
and hot melt adhesive labels with a throughout of up to
60,000 bottles per hour. Five different glass containers
are processed on the Bad Peterstal machine: 0.5-liter
GDB, 0.7-liter GDB, 0.25-liter restaurant, 0.5-liter restau-
rant, and 0.75-liter restaurant bottles.
The German Mineral Water Ordinance requires mineral
water to be sold only with an originality guarantee. This
can be implemented using a screw cap with a tamper-evi-
dent seal, or with a seal using a label. Peterstaler Min-
eralquellen has always used label sealing, and wanted
to keep that solution. The shoulder label used for this
purpose has a strap pointing up, which is applied to the
twist top using a hot melt glue point. When the bottle is
opened, the paper label tears between the cap and the
shoulder of the bottle, and making it visible that the bottle

hold of the sealing label,“ says Andreas Felder, Sales
Lead Southwest at the German Robatech subsidiary in
Bad Camberg. The glue points are also inspected for
presence by an infrared sensor. Bottles without a sealing
label glued in place are sorted out. „Application control
is done by the Robatech AS 50 AK control unit, which is
connected to the KHS system controller by Ethernet. That
lets the customer control our pattern control from the KHS
touch screen.“
Wolfgang Sum is extremely satisfied with the adhesive
application system from Robatech: „I was already familiar
with spray adhesive technology from Robatech and really
wanted to have that kind of system in our new glass filling
line again. So we were excited to find that KHS already
recommends an adhesive application system from
Robatech in their Innoket Neo.“ KHS primarily integrates
thread on the outside, using a single point would run the
risk that the hot melt would happen to fall inside a thread.
Using two points guarantees that at least one thread
ridge gets glue, which is necessary to ensure the secure

relies on technology from Robatech AG, headquartered in

A Robatech Concept B5/2 melting system melts the

hose. A single application head is used. „With the Speed-
Star, KHS rotary labelers now apply two hot melt points
to the cap. Since the aluminum screw caps also have a

KHS. Systems from Robatech can also be upgraded into
existing lines without any problems.
„Since we only fill on a single glass line, availability is
vital for us,“ says Wolfgang Sum. „The perfect quality of
Robatech adhesive application technology offers us high
reliability in production. Contact with Robatech service
technicians is also competent and direct. If we run into
even a small problem, it gets solved immediately. We
are also satisfied with the sustainability of the system,
because it lets us reduce not only power consumption but
glue consumption as well.“ The new glass filling line was
opened in February 2016, and has run problem-free ever
since.
