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

A Robatech Concept B5/2 melting system melts the

hose. A single application head is used. „With the Speed-

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.
