Precision and performancein high speed handling
Mineral water, soft drinks, beer – more and more beverages are bottled
today in lightweight, unbreakable PET containers. These are produced atbreakneck speed: the Krones Contiform 3 series of stretch blow moulders
impresses with up to 81,000 bottles per hour. TP+ 050 HIGH TORQUE
low-backlash planetary gearheads guarantee maximum precision anddynamics when preforms and containers are handled at high speed.

Millions of PET bottles are manufactured and filled worldwide every day on Krones machines – for example by soft drink manufacturers.

The Krones Group, headquartered in Neutraubling (South Germany), develops andmanufactures machines and complete lines for process, filling and packaging technology. "Our clients see us as an all-round vendor where mechanical engineering, line expertise, process engineering, microbiology and information technology have been harmoniously integrated for optimum synergies", explains Thomas Höllriegl, Team Leader
Plastics Technology at Krones. Every day, millions of bottles, cans and special-shaped
containers are handled worldwide on Krones lines, particularly in breweries, the softdrinks sector and at producers of still or sparkling wines and spirits. High speed is aprecondition of maximum productivity in all these applications – and all the machinecomponents have to engage with one another without any loss of momentum.

Applications

PET preforms on their way to theblowing wheel, where they are placed inmoulds to be moulded into containers
by compressed air and heat

The stretch blow moulders in the Krones Contiform 3 series
impress with up to 81,000 PET bottles per hour.

From thumb-sized preform to 3.5 l bottle
81,000 bottles an hour – equivalent to two bottles in less than theblink of an eye – the Contiform 3 makes each bottle so fast that thehuman brain simply can't keep up. Depending on the design, thisstretch blow moulder can handle containers with a volume of 0.1 to
3.5 litres. The process is basically identical. The prefabricated preforms are first carried through a linear oven, where they are heated

6 moveup to their optimum processing temperature. From there they aretransferred by the grippers on an infeed starwheel to the blowing
wheel, where they are placed in moulds to be moulded into containers by compressed air and heat. The finished bottles are then removed from the blowing station by the outfeed starwheel and fed toan air conveyor, which takes them to the filler. Each of the machine's
transfer systems is equipped with individual servo actuators as well
as low-backlash planetary gearheads made by WITTENSTEIN alpha –for good reason.
TP+ 050 HIGH TORQUE: Optimized with maximum
torsional rigidity and minimum torsional backlash"The highest possible positioning accuracy, even if the torques at thetransfer starwheels vary considerably – that was the central challenge
our planetary gearheads had to address", says Markus Kleinhenz,a sales engineer at WITTENSTEIN alpha, looking back. "That's
why we decided to equip the drives for the Contiform 3 with

low-backlash planetary gearheads in the TP+ 050 HIGH TORQUE
series", Höllriegl adds. Both the infeed and the outfeed starwheel
which are used to move the PET preforms have an integral gearheadin the column. In addition to high dynamics, these gearheads also
provide maximum torsional rigidity and minimum torsional backlash.
These are crucial characteristics without which ultra-precise handling of the preforms and bottles at high speed would be impossible
in continuous operation. The high dynamic loads associated withthe starwheel movement further complicate the situation: "The tension springs in the grippers of the transfer starwheels, which moveon rollers in a cam track and prevent edge changes, result in strong
torque variations in the system", Kleinhenz continues and confirms:"These effects are compensated thanks to the extreme stiffness of
the TP+ gearheads".
Heat dissipation for a "cool" working atmosphere
One particularly "hot problem" for the engineers who designed the transmission technology concerned the thermal stress at the blowing wheel's infeed starwheel. The
Contiform 3's linear oven transfers the PET preforms
here at temperatures up to 120°C. The heat from thesepreforms and the starwheel column motor leads to highthermal loads on the entire drive unit. "In continuous operation, the temperature at the gearhead housing canexceed the specified 90°C limit", Kleinhenz reports. To
rule out this possibility and simultaneously lessen the thermal stresses on the motor in this application, WITTENSTEIN
alpha developed a special adapter plate with water flowing
through it. When connected to the machine's existing temperature
control circuit, it effectively reduces the temperature at the gearhead
and motor.
Precision, dynamics, availability – WITTENSTEIN alpha's low-backlash planetary gearheads get PET preforms into top shape at Krones.

PROFESSOR JOHANNA WANKA,FEDERAL MINISTER OF EDUCATION AND RESEARCHHERMES AWARD 2015
And the winner is…

The "Oscar for engineers" goes to WITTENSTEIN
Oscar and HERMES – two awards for outstanding achievements:
Whereas the annual Academy Awards are handed out to the best
cinema films and their makers, the coveted technology prize isreserved for industrial companies and especially impressive feats ofengineering.

WITTENSTEIN's revolutionary Galaxie® Drive System is unquestionably an outstanding innovation – and an ingenious idea that was selected this year from a field of almost seventy entrants from ten different countries. It was submitted by a manufacturer which has beensynonymous for many years with drive engineering expertise.
The media were unanimous in their praise following the world
premiere at the Hannover Messe last spring: "A new era", "You
won't find it in any textbook", "A new performance universe".
Experts and the HERMES AWARD jury were in total agreement:"The high performance Galaxie® Drive System is an outstanding
development and a prime example of Germany’s innovative drive.
WITTENSTEIN has proved that with courage, creativity and determination a completely new kind of gearhead can be created. The
company has also succeeded in embodying the future of industry –8 movethe networking of production and services – in its gearbox", said
Professor Johanna Wanka, Federal Minister of Education andResearch, in her address at the award ceremony in the presenceof Chancellor Merkel.
Thomas Bayer, Galaxie's inventor and Head of Galaxie Drive Systems at WITTENSTEIN AG, is also firmly convinced: "The Galaxie®
Drive System will open more new doors for development engineers than any invention during the last several decades. The first
customer projects have already confirmed Galaxie's® standing
as the enabler for the next generation in high performance engineering." Bayer cites one specific reason for his huge pride inreceiving the award: "It demonstrates that even in the digital age,springboard innovations are still possible, even when it comes tothe basic fundamentals of motion in industrial drives."

The radically new gear tooth principle is based on the logarithmic spiral –which occurs in nature in the form of a snail's shell, for example.
Professor Wanka expressed this very succinctly in her own words:"Everyone knows what a gear wheel looks like – and now, out of the blue,
we're suddenly confronted with the idea of building a gear with moving
teeth. You won't find it in any textbook, but it works!" For the first time
ever, a gearhead dispenses completely with a gear wheel – instead,each of the teeth involved in torque conversion is an independent anddynamic entity, which is supported by a needle roller bearing, groupedaround a two or three-cam input polygon and guided along the teeth ofa ring gear. As a result of this ingenious concept, almost all of the teeth
now engage simultaneously. Thanks to the new engagement principle,
the tooth contact is no longer a line but a surface.

Profiling rotationally symmetric parts such as motor shafts or spindles is a corecompetency of Profiroll Technologies GmbH. Since integrating the Galaxie® Drive
System in its Rollex spline rolling machines, the company has significantly increased
its productivity. The extremely high torsional rigidity of the Galaxie® Drive System has
played a vital part in this efficiency leap. It is the result of a revolutionary kinematic
principle – and almost six times higher than with any other type of gearhead. Thisfeature of Galaxie® particularly impressed Profiroll's machine designers.

Profiroll Technologies: A partner for professional profile rolling
Profiroll Technologies GmbH of Bad Düben (East Germany) is a leading manufacturer whose machines areused, amongst other things, in the automotive / aeronautic supplier industries to profile rotationally symmetric parts using cold forming technology. "The Rollex series enables profile rolling of splines onto symmetricalshafts", explains Dr. Stephan Kohlsmann, General Manager of Profiroll Technologies GmbH. "The rolling
process is based on the circular die principle. The workpiece is positioned inside the work area, clamped
between centres. The rolling slide infeed then starts up, causing the circular CNC dies on the slides to penetrate the workpiece and cold-form the required spline profile. Top quality serrated, hobbed or hollow splines
are the result."

Spiral nebulae and Galaxie® both follow the

move 11Vibration in the powertrain is a productivity killer
Until now, however, severe vibration in the entire powertrain has
been unavoidable with certain types of spline depending on the machining speed. "In the past, this used to mean significantly reducing
the rolling speed for these particular parts in order to meet the highquality and dimensional accuracy requirements", Kohlsmann recalls.
It was the old cycloid gear that was causing the vibration: the torsional rigidity at high moments of inertia was not sufficient, leading
to excessive powertrain vibration. "We didn't want to switch to another standard gear type because any improvement in the torsional
stiffness would have had negative impacts on other performancefeatures", he continues.
This is not the case with the Galaxie® Drive System. "Improvements toone feature are not at the expense of other performance parameterslike freedom from wear and backlash, dynamic positioning accuracy

or load carrying capacity – on the contrary, it beats all similar sized
gearhead series – often hands down – in all important technical details", claims Volker Sprenger, Head of Sales Galaxie Drive Systems.
Galaxie ®: extremely quiet running at any speed
The integration in Profiroll Technologies spline rolling machines
demonstrates most impressively how the Galaxie® Drive System candramatically improve performance features. Its extreme torsional rigidity, which is almost six times higher than with any other type ofgearhead, is crucial in this application. There are practically no bending lengths owing to the special design principle. At the same time,
the teeth in contact are automatically aligned because they are guided cylindrically in the tooth carrier, leading to optimal engagementwith the internal gear teeth. The outcome: a gearhead that combinesabsolute freedom from backlash with maximum torsional stiffness.

VOLKER SPRENGER,
HEAD OF SALES GALAXIE DRIVE SYSTEMS, WITTENSTEIN AG

The basic idea behind the
Galaxie’s® kinematics: eachof the segmented teeth is anindependent and dynamic entity,
which is supported by a needle
roller bearing, grouped around a
two or three-cam input polygon
and guided along the teeth of aring gear.

Success through co-engineering
In theory, this was exactly what Profiroll was looking for – yetwould it also turn out to be true in practice? To make sure they
were on the right track, WITTENSTEIN's engineers had to become thoroughly familiar with spline rolling techniques. "We
were then able to understand how the process interacts with the
Galaxie ® Drive System and model it together in such a way thatthe technical benefits for the Rollex were visible", Sprenger states.

Profiroll customers in manydifferent industries – fromautomotive and supplies
through linear technology,
aviation and rolling contact
bearings to energy – value
the superior performanceand productivity they getfrom the Galaxie® Drive
System, which helps
them launch into a new
performance universe.

The teeth in contact areautomatically aligned
because they are guided
cylindrically in the tooth
carrier, leading to optimalengagement with theinternal gear teeth.

Once the Galaxie ® Drive System was integrated in the first pilot machine, the rolling speed was continuously increased in tests withselected critical parts – until it eventually exceeded 120% comparedto the old baseline. Supplementary calculations showed that if theprocess speed is increased by "only" 1.5 times, productivity shoots
up 40%. "While non-productive time remained constant, the number of machinable workpieces rose from 4 parts per minute to 5.1 –in other words 29% more", Kohlsmann confirms.

Automated guided vehicle systems
intelligently driven
Compact, powerful and energy efficient – these are the key requirements specified for the drive
components of automated guided vehicle (AGV) systems. BeeWaTec trusts absolutely in integrated
system solutions from WITTENSTEIN motion control.

Motion control intelligently designed
At the heart of the Traction Drive System (TAS) is simco® drive, thesmart servo drive which is also integrated in the brushless DC motor. "As a servo drive for the Traction Drive System, it's perfect because it enables high-precision torque control as well as high dynamics in the current control loop", explains Nadine Hehn of ProductManagement at WITTENSTEIN motion control GmbH. "The AGV
system can therefore execute travel and positioning motions very

again by an AGV. "These are often complex, single-axis movements
which can be generated optimally by a control system with distributed intelligence, in other words directly by the simco® drive", elaborates Dr. Oliver Barth, Assistant to the Executive Management at

The company offers complete system solutions for inhouse logistics, from AGVs through milk runs to complex manufacturing and logistics systems. "Modular mini systems are very muchin demand at present", says Jens Walter, who is on BeeWaTec's Executive Management together with Joachim Walter. "Many featuresof our Bee_Mini, for instance, are scalable such as the load capacity,

Compact motor-controller unit for optimal load restraint
A brand new vehicle for transporting stacked containers underlines
this claim: "We're the first to have developed this kind of transport
concept for an overall weight of 150 kg", Joachim Walter reports. Up
to five containers with a maximum of 30 kg each are stacked on abase frame with casters. Jens Walter describes the special design:"The vehicle picks up the stacked unit in one go". As soon as the container is completely in the vehicle, the shutter closes and the load
is secured by the clamping mechanism." The drive system which
is used to clamp the containers in the vehicle comprises a brushless DC motor in the cyber ® dynamic line family and a simco® drivewith IP20 protection. "This brushless DC motor system clamps thestacked container unit by force control", Joachim Walter continues.
A motion task with all the necessary parameters was programmed
locally by BeeWaTec for this purpose in the servo drive using MotionGUI.
Traction drive in plug-and-play design
BeeWaTec is also treading new paths with its traction drives – with
the Traction Drive System (TAS) as a complete, easy-to-integrate
actuator unit. Each group of components comprises a TPM+ servo
actuator and a simco® drive. "Thanks to various optional features,
we can tailor the design of the actuator systems to the requirements of each individual customer or application", says Jens Walter.
"What's more, by presetting the actuator system parameters in our
MotionGUI software, we can integrate them in the vehicle quickly
and easily." Both the servo drive and the servo actuator are unbeatably compact and power-dense. The Traction Drive System facilitates
flatter, narrower and lighter vehicles. A further advantage is that thehigh energy efficiency permits long driving cycles without charging,so that vehicle availability is higher.
One-stop engineering reduces time and cost risks
The fact that both actuator solutions could be purchased from asingle supplier was a crucial argument for BeeWaTec: Joachim andJens Walter speak with one voice: "We always prefer to work withsystem partners like WITTENSTEIN motion control". "One-stop consulting, plus the integral design and optimal interaction of the actuator and control technology, enables us to eliminate interface risks –and hence extra costs and unnecessary lost time – during the planning and production phases of our AGV systems."

PROFESSOR RAINER BAUMGART,CENTER FOR CORRECTIVE AND RECONSTRUCTIVE SURGERY
OF EXTREMITIES (ZEM) GERMANY IN MUNICH

Martina Kappes reports in avideo on her experience with
FITBONE®.

"Part of the concept is to have at least
one COE with experienced surgeonsin each country where this kind ofoperation is carried out regularly",
Professor Baumgart explains.

Functional shoes, not fashion footwear
When Martina Kappes was six years old, her paediatrician discovered that her right leg was about two centimetres shorter than her
left. What followed would probably class as a major disaster for any
young girl: instead of wearing pretty shoes like her friends, she wasforced to put up with unfashionable orthopaedic footwear. The leg
length discrepancy increased year after year as she grew up into ayoung woman. "It had become four centimetres by the time I was16", Martina remembers. "As time went by, I also started to feel thenegative effects of the shorter leg more and more: pain in my back,hips and knees."
FITBONE®: short operation, virtually no pain,
no ugly scarring
There are probably almost no patients who actually jump for joy
when their doctor tells them they need an operation – and Martina
Kappes certainly wasn't one of them. She expressed a number offears: a complicated operation, a painful healing process, awkward
fixators on her leg, a long hospitalization period, restricted mobility and a reduced ability to participate in everyday work and leisureactivities. "When I learned that thanks to FITBONE® a solution also

18 moveexists without any of those impairments, I was incredibly relieved",
Martina recalls. She first heard about it from her husband, whoworks for WITTENSTEIN and told her all about the intramedullary
lengthening nail. "FITBONE® is a fully implantable system that combines uncomplicated treatment with excellent cosmetic results", explains Professor Rainer Baumgart of the Center for Corrective andReconstructive Surgery of Extremities (ZEM) Germany in Munich. It
didn't take Martina long to be convinced of the FITBONE® principle: the intramedullary lengthening nail is completely implanted in thebone as a keyhole operation, in other words as a minimally invasive
procedure with only tiny cuts. This has several advantages for thepatient: small-to-very small scars, no external fixators and no risk ofinfection at the body exit points.
Wheelchair-free convalescence
Only twenty-four hours later, the leg had recovered sufficiently tobear at least part of Martina Kappes' weight again and she was able
to attempt her first steps with crutches. She was discharged from
hospital within a few days and subsequently controlled the distraction process herself in the comfort of her own home. She was provided with a handy little external control set for this purpose, which

activates the motor in the intramedullary nail and carefully extends
it. "About one millimetre every day, to make sure the bone growthis just right and doesn't cause any pain" Martina adds. The bonein her thigh was gradually lengthened in this way until after approximately five months, the treatment was completed and the leg length
discrepancy compensated. "Throughout the treatment period I wasable to lead a normal life without pain and without being restricted bya wheelchair, for instance", Martina reports.
Safe procedure performed by experienced FITBONE®
surgeons
The FITBONE® was removed again after about a year. Both the procedure itself and the implant insertion took place at ZEM Germany inMunich – a so-called Center of Excellence (COE). All FITBONE® operations at the COEs are performed by highly specialized surgeons
with years of experience in the correction of leg length discrepancies
and special training from WITTENSTEIN intens in the use of the intramedullary lengthening nail. "Part of the concept is to have at least
one COE with experienced surgeons in each country where this kindof operation is carried out regularly", Professor Baumgart explains.

The unique COE concept gave Martina Kappes
the confidence she needed: Several thousand
FITBONE® systems have been implanted to date,and in almost every case they have proved to betechnically reliable and the operation non-critical – even where complicated procedures arenecessary, FITBONE® is an excellent product.
With appropriate preoperative planning andsurgical techniques, it is possible to carry out
axial and torsional corrections as part of limb
lengthening in a single operation. "That certainly
eases the decision to go under the knife", Martina
confesses.
She hasn't once regretted undergoing the
FITBONE® procedure. "I would absolutely makethe same decision again and I wholeheartedly
recommend it to anyone suffering from thesame problem. At the very latest when you canwalk straight again without feeling pain, you aregrateful for the new quality of life the FITBONE®
system gives you."move 19

All linear actuators in the cyber ® force motors portfolio can be supplied inthree variants. “When only limited space is available for installation, our highly
compact linear motors with a highly integrated ball screw are the best choice”,
explains Carolin Ank, Product Manager at WITTENSTEIN cyber motor GmbH.
Another advantage is that thanks to their patented lubrication system, these
motors require virtually no maintenance and allow the ball screw to be regreased without disassembly. And at the customer's request, WITTENSTEIN

...endless screw
Hollow shaft actuators with an endlessscrew are ideal for applications

Rough conditions
When particularly rough conditions demand a special design, screw-type actuators are ready to confront the challenges:
operating environments up to 300°C, forexample, radiation fields up to 107 Gy or
operating pressure down to 10 -8 mbar
are not a problem. Other variants are
specially rated for applications inhazardous areas or suitable for food andbeverage contact. Customized actuator
designs are a must here because theequipment has to be thoroughly cleaned
and disinfected.

Electromechanical cylinders with a directly driven motor shaft, designed
as a ball screw shaft, are another option. Owing to their special designprinciple, they are a financially attractive alternative which is perfect for
all highly dynamic applications where space is not an issue. Whereas thestroke of both these variants is defined by the screw length, hollow shaft
actuators with an endless screw are suitable for applications with an "endless" stroke – even with compact sizes.
Rotary and linear motion in one
For positioning tasks where both a linear and a rotary motion are required,the combined linear-rotary actuators of cyber ® force motors with two actuators in one housing are the ideal solution. The two motions can becontrolled independently of one another – and the compact design of thelinear-rotary actuators simplifies their mechanical integration.

that these fully integrated actuator units perform optimally, all duty cycles and requirements areindividually calculated using a software sizing tool". The design can also take account of customized or application-specific components, so that a feasibility assessment and a made-to-measure
implementation concept can be submitted to the client within a few days. Thanks to the modular
design, for instance, several different motor encoders can be realized for position control and theactuators connected to any standard industrial controller. From there, it's only a short step to thefirst functional model and a rapid production ramp-up – especially since WITTENSTEIN cybermotor can make use of proven, approved and certified servo motors manufactured in-house. The
special WITTENSTEIN quality standards for design, production and functional testing guarantee
optimal reliability in the most diverse applications.
Optimal availability in standard or extreme applications
Highly compact, high torque, customized – three outstanding attributes of the linear actuators
used for cyber ® force motors in a wide range of applications. They are just as impressive at assembly workstations as they are in complex mating and pressing processes, in capping systems forfilling and packing food and beverage products, when reshaping plastic film or metal sheets or forclosing and dispensing axes in injection moulding machines.
The linear and combined linear-rotary actuators of cyber ® force motors are well established ascompact, ready-to-mount and technically and commercially optimized solutions. Due to their modular design, these actuators can be adapted to almost any requirements. They meet the needs ofthe applications without compromises – and with real benefits for customers.

If your colleagues welcome you every morning with a cheerful "Grüezi", the chances
are you work in Switzerland – like the 38 WITTENSTEIN sales, development andproduction staff in Grüsch (a small village in the Grisons canton). WITTENSTEIN
first moved into premises there back in the year 2000 and for the last five years the
production and administrative building in Trutwisstrasse 1 has been home to theGroup's centre of competence for racks.

High-tech production in a mountain valley
WITTENSTEIN Switzerland celebrates 15 years

The Group's competence centre for racks
is situated in Grüsch,not far from the regional capital of Chur in the
Alpine Rhine valley.

Originally set up mainly as a Swiss sales company for the
WITTENSTEIN Group, WITTENSTEIN AG (Switzerland) has
meanwhile been part of the industry community referred to as"made in Grüsch" for 15 years. This WITTENSTEIN subsidiary
initially shared the same roof as INNOZET, a burgeoning centre
for start-up companies, in creative proximity to TRUMPF, another resident. However, it did not take long to gain a foothold in
the Swiss market with innovative, high quality, drive technology. A new building on an adjoining site for WITTENSTEIN's sole
use was officially opened in 2010; an elegant, light-filled structure costing 17 million Swiss francs and clearly visible from afar,
it marked the start of a new development phase. With 2000
square metres of production space and 1000 square metresof offices, there is now ample room for the three business segments which are the specialities of WITTENSTEIN Switzerland
and General Manager Gerhard Horn: the manufacture of premium racks, the development and production of sensor technology

Group's complete product portfolio. "We set great store by abuilding in which production and offices are in close physicalproximity. Staff in Production, Development and Sales can get
together at short notice to discuss new ideas or tackle any problems which arise. When I look back today, I think you could say
we succeeded", says Dr. Anna-Katharina Wittenstein, Chairperson of the Board. She chooses the imagery of the surrounding
mountain landscape to formulate the current – and altogether
ambitious – production target: "We're aiming this year to build
enough racks to reach all the way from Grüsch to the top of our
local Schesaplana mountain – 18 times over!"Incidentally, the close cooperation with INNOZET has continued right through to the present: 200 square metres in Trutwisstrasse 1 are let out to the Grisons Start-up Foundation.

A new assembly line for high-end gearheads in the SP+ and TP+ series recently went into
operation at WITTENSTEIN North America. The investment is a central element of the
WITTENSTEIN Group's globalization strategy which simultaneously lays the foundation for
future growth at the Bartlett facility in Illinois.

Bartlett (from left to right): Dr. Lars Aldinger(Executive Vice President Production andLogistics) and Anthony DeCore (Team
Leader Assembly) with Assemblers Kevin
Sanches and Enrico Cunanan"Local production"
The decision clearly underlines the importance of the North American market for WITTENSTEIN. Ever since alpha gear drives Inc. wasfounded – in 1992, sowing the seeds for what is today WITTENSTEIN
North America with 95 staff on the payroll – it has practised a forward-looking philosophy of creating added value close to where its
customers are located. A modular assembly line for the LP gearheadseries was gradually established, first in Elk Grove Village and later in Bartlett, near Chicago. It was successively upgraded over theyears to a full-blown assembly line. Parallel to this, the proportion ofcomponents manufactured locally was continuously increased. The
production of mechatronic systems expanded to match: the portfolio
meanwhile also includes mechatronic drive systems for safety technology as well as aerospace simulators.
Realignment: "fit for growth"
As part of the realignment, WITTENSTEIN managed to bring its Bartlett production processes into line with the requirements of twenty-first century North America in just 8 months. Priority was given
to accelerating the supply chain to the end customer. All value flows
were designed for efficiency and speed and local production capacities extended, to enable the Assembly department to be provided
with parts even faster, more flexibly and more efficiently. Today, hightech production facilities with automated peripherals ensure a highoutput and consistently high quality. WITTENSTEIN also invested in
improved order processing reliability. All material and equipment arelabelled with QR codes to allow them to be uniquely identified at any
time.
Local production of high-end SP+ and TP+ gearheads
The present lean, stable value chain has been crucial for the successof the new SP+ and TP+ gearhead assembly line. Designed according to lean manufacturing principles, this line places the emphasis
even more firmly on the customer: since the beginning of the year,
production on two assembly lines has been aligned to each client's
own pace, with the result that customer-specific modifications canbe realized promptly and just as easily as orders from key accounts.
The majority of products for the North American market are thus
manufactured locally. It's a situation that is much appreciated bycustomers because end-to-end assembly in the country concernedmeans better flexibility and responsiveness while simultaneously
shortening delivery times. "We're very proud of the fact that we can
now make our main gearhead lines – LP+, CP, SP+ and TP+ – to orderon the spot in the U.S. Customer proximity is no longer simply a slogan. The supply chain the customer has been substantially accelerated", says Dr. Lars Aldinger, Executive Vice President Production &Logistics and as such responsible for the production facility in North
America. "Preferred series – like the LP+ gearheads – are shipped
within 24 hours of the order being placed."
Customer retention through quality and service
The assembly line and its networked workstations conform to thehigh WITTENSTEIN quality standards in every respect: "To makesure our high level of quality worldwide is also maintained at the Bartlett production site, we provided a few weeks of intensive training toassembly and engineering staff at our German headquarters. That
helped us get our new line up and running fast and successfully.
It will also empower us in the long term to make gearheads thatcomply with the very highest quality and availability requirements",
explains Anthony DeCore, Team Leader Assembly in Bartlett. Peter
Riehle, President and CEO of WITTENSTEIN North America, is noless enthusiastic: "The market has reacted extremely positively to
our expanded production and service capacities. Our customers are
grateful for the far shorter delivery times and the high flexibility no
matter what the volume. Another important criterion is that our service technicians can provide prompt on-site support where necessary and reduce machine downtime to a minimum by getting spareparts out there very fast."
WITTENSTEIN North America will continue to strengthen its customer service systematically, from the custom-tailored delivery of products to the place of use through private labels and prepacking aswell as electronic order data tracking to web based information in theframework of our Industry 4.0 activities.
Flexibility, prompt deliveries, quality and service – WITTENSTEIN
North America proves that creating added value locally helps put ourcustomers in the fast track.

The VDI's highest award for outstanding professional services
in the field of science and technology

The engineer as an artist
Grashof medal for Dr. Manfred Wittenstein
What have Carl Bosch, Alfred Krupp, August Wilhelm Maybach, Ferdinand Porsche, Werner vonSiemens and Ferdinand von Zeppelin got in common? Firstly, their engineering achievements arelegendary. Secondly, they are all holders of the commemorative medal originally presented by the
Association of German Engineers (VDI) in 1894 in memory of Franz Grashof, the VDI's co-founder
and long-time Director. It is widely regarded as the highest award to engineers for outstanding
professional services in the field of science and technology. Dr. Manfred Wittenstein is the mostrecent recipient of this prestigious accolade.

»There is no doubt in my mind that engineers
are also artists; after all, they too must
be creative and they have to come up withnew things. High creative potential is vital.«DR. MANFRED WITTENSTEIN,CHAIRMAN OF THE SUPERVISORY BOARD, WITTENSTEIN AG

The VDI's Grashof medal was originally presented in 1894 in memory of Franz Grashof (Professor of Theoretical
Machine Design at Karlsruhe Institute of Technology as well as co-founder and first Director of the VDI from 1856 to1890). It is an award made to engineers for outstanding professional services in the field of science and technology.
Embossed in gold, the medal depicts Franz Grashof on the front with the recipient's name and the year on the reverse.

The German Engineering Federation (VDMA) was delighted withthe prestigious award for its
former President (until 2010):"He is one of the foremost engineers and entrepreneurs of ourtime – a man of vision with thecourage to innovate. His commitment to excellent engineeringachievements, innovation andintelligent production sets an
outstanding example.
Dr. Wittenstein has been dedicated to the advancement of theGerman engineering industry
for many years now. He is asought-after advisor on innovation policy at a regional, national
and European level. His name issynonymous with social responsibility and a holistic innovation
culture, founded on the self-perception of Germany's culture oftechnology and inspired by a respectful, cosmopolitan outlook",
said Hartmut Rauen, the VDMA's
Deputy Executive Director.

»As engineers, we have a fundamental mission
to make people's lives easier, to build toolsthat get people ahead. Industry 4.0 is the best example.
Our goal is to be at the forefrontof this trend.«
DR. MANFRED WITTENSTEIN

Dr. Manfred Wittenstein (right)
was recently honoured with the
VDI's Grashof medal for his life's
work: this distinguished award
was presented to him by VDI
President Dr. Udo Ungeheuer(left) at the 27th German Engineers' Convention.

"Thinking Generations – Innovations for Germany" – the motto for this year's German Engineers' Convention, which provided aworthy backdrop for the award ceremony, could not have been better chosen for Dr. Manfred Wittenstein, aged 73, the newest recipient of the Grashof commemorative medal. Long acknowledged as avisionary among machine builders, Dr. Wittenstein transformed thefamily firm he took over from his father in 1979 – which at the time
was still specialized in the manufacture of double chainstitch machines for glovemaking – into a successful global player in the field of
mechatronics and drive technology.
According to Wittenstein, for whom engineering is a passion, "his"profession is one that holds considerable meaning: "I take the viewthat an engineer combines the image of an artist and a master who
succeeds in bringing creative competencies to life and in putting
them to practical use in an interdisciplinary dialogue. To serve people with controllable technology and develop tools that overcome
the challenges of the future – it's a wonderful task which awaits thenext generation of young engineers. I take pleasure in accepting thisaward on behalf of all staff – in anticipation that it will guide and motivate us to continue acting with courage in the years to come", theChairman of the WITTENSTEIN AG Supervisory Board commented
on receiving the prize for his life's work.
He formulated his own personal hope for Germany's future as amanufacturing location and innovation leader with an image borrowed from nature: "The contribution being made by German engineers as industry launches into a new, digitized and networked
era is perhaps not yet fully clear. We are currently experiencing thewater lily principle as Industry 4.0 takes off." In winter, there is not asingle flower to be seen in the pond, yet in summer the entire surface
bursts into bloom as if by magic. Processes that have been hiddenfrom view for several months suddenly become visible to everyone.
"To abide by this metaphor", Wittenstein continued, "we're now in the
middle of spring".

Technology. Not a question of age!
A WITTENSTEIN initiative:
Youth Technology Learning Centre

Air is "not nothing": although normally invisible, it exerts a
tremendous force on its surroundings. The insatiable desireof children, teenagers and young adults to understandnatural phenomena such as this – by experimenting,building models and trying things out – can now besatisfied under professional guidance.

The “Jugendtechnikschule Taubertal” (Tauber Valley Youth Technology Learning Centre) was set up by WITTENSTEIN AG in cooperation
with regional partners in industry and the general public. This new,independent, extracurricular education initiative supplements thecompany's traditional commitment to youth advancement in the areas of mathematics, informatics, the natural sciences and technology:
the annual scholarship for school leavers aspiring to study a science
subject and the "Creative Young Minds" competition for fledgling inventors have now been joined by a creative "little sister".
You can't begin soon enough
Just in time for the start of the new 2015/16 school year, boys andgirls from pre-school age upwards now have a chance to gain theirfirst playful insights into the huge world of modern technology andengineering. "There are plenty of out-of-school activities for children
and young people to try out in other areas like sports", says Karin
Markert of WITTENSTEIN AG. A manager in the company's Human
Resources department, she has collaborated extensively with Xaver
Schützenmeier, who works as a trainer, on the development of the
new project. "A lot of youngsters leave our region when they finish

The Tauber Valley Youth Technology
Learning Centre aims to arouse curiosityand a fascination for technical details.
Its programme is targeted at various
age groups – from pre-school children to
young adults – and is equally suited forboys and girls.

A variety of workshops, courses and projects are offered by the Tauber Valley
Youth Technology Learning Centre in cooperation with partners in industry,
schools, kindergartens and the general public.
The world of technology is explained by playful means: those taking part have achance to deepen and expand their knowledge, develop practical skills, creativity
and inventive spirit and in some cases gain a glimpse of the opportunities for a
future career.

can succeed in arousing the enthusiasm of just a few of them fordelving into the mysteries of science and tinkering around to finda solution at an early age – and if we can show them which career
opportunities that can open up for them locally – it will be a win-win
situation. The initiative will benefit us, other companies in the region,
the region itself and above all the young adults who are persuaded toreturn maybe several years later to the place they call home as highly
qualified specialists.
Encouraging creativity and inventive spirit has long been a matter close to the heart of Dr. Manfred Wittenstein, the proprietor of
WITTENSTEIN AG. The official opening of the Tauber Valley Youth
Technology Learning Centre moreover represents the fulfilment ofa promise he made on the occasion of his 70th birthday: instead ofgifts he asked for donations for his newest project to promote unconventional methods for youth advancement. The Centre receives
financial support from the WITTENSTEIN Foundation; the first exciting, practically relevant workshops and courses have already begun
there under professional guidance. Iris Lange-Schmalz, the Centre's

Director who also oversees the "Creative Young Minds" competition
for budding inventors, is delighted at the success of the preliminary
test runs: "We had an awful lot of visitors to our 'Technology Days' inthe spring. That's why we decided to publicize the new programmein Bad Mergentheim Castle. Incidentally, we've been lucky enough to
be given the use of rooms there belonging to the Bad Mergentheim
Campus of Baden-Württemberg Cooperative State University Mosbach."
It won't be long now before the Centre gets properly off the groundwith the first project phase this autumn. The programme of activities
is certainly very tempting: "Experiments with a splash – let's build
a squirt gun. How do water pumps and turbines work?" "Hot wire –let's build a game of dexterity with an electronic circuit", "Sharpener
robot – the school butler", "Let's build a traffic light" or "Old tractors –technology meets driving pleasure". Plus, of course, the workshop we mentioned at the very beginning called "Experiments withair". It's a safe bet that the new Tauber Valley Youth Technology
Learning Centre will soon be exerting a tremendous force on its
surroundings too!
