Before investing in systems en-gineering, a number of questions must be answered. For example, whether a system works as perfect in practice as in theory. Or whether you will be able to achieve the desired result with the existing raw material under the existing production conditions. The two TRÜTZSCHLER NONWOVENS Technical Centres give a clear an-swer to these and other questions.

First be sure, THEN INVEST

On a total area of more than 5,000 m2 you have the opportunity to test all production methods on a large industrial scale - of course also with your own materials. Next, de-tailed material analyses are possible in our well equipped laboratories at both locations.

Belt WeigherThe highest level of precision is required for continuous weighing and blending of fibers after bale opening. With its unique high accuracy of measurement, our belt weigher ensures that the addition of fibers is restricted to the neces-sary minimum. This results in significantly lower costs, which translates into an economic ad-vantage especially in case of expensive fibers. For lower production efficiencies, discontinuous weigh pans are available.

A measuring tolerance of +/- 1 % makes the erko belt weigher the most accurate one on the market. This allows significant savings in material.

highest degree of homogeneity

Mixing ChamberOur modern tuft blending installations optimally mix fibers of different types, lengths, finenesses and colours. In addition, our mixing systems are individual, easy to operate, reliable and depend-able. This is of particular importance when a large amount of different fibers requires ab-solutely homogeneous processing.

erko fine opener erko chute feeder

supreme quality

Continuous feeding

Fine OpenerThe fine opener lives up to its name and opens fibers in such a fine and gentle manner that for certain products direct bonding is possible with-out any intermediate roller cards. In other cases the fine opener allows the use of roller cards with less carding points. This lowers investment costs and increases productivity.

Chute feederThe Erko chute feeder serves as material buffer between blending line and card feeding. It features feed rolls and a pinned opening roller that ensures uniform card feeding with small tufts. The speed of the feed rolls is continuously adjusted (CONTIFEED) via a pressure monitor-ing system that monitors the filling level in the downstream card feeder. This guarantees a con-sistently high web quality in the finished product.

The direct way to outstanding quality

Tuft feedingAt this point, the basis for future product quality is irrevocably established. For this reason we have developed – and are successfully imple-menting – two high-performance alternatives to the state-of-the-art technology. They are based on the principle of pressure feeding, which has such a high degree of accuracy that with some products even downstream roller cards can be eliminated. The web is passed directly into the web bonding machines, resulting in outstanding quality at low investment costs.

EDSWLWhether very coarse or extremely long fibers – the EDSWL ensures homogeneous fiber feed-ing, which can be permanently monitored and adjusted by a downstream belt weigher.

SCANFEEDThanks to the homogeneous fiber feeding, the web quality at this point is already very good. In lines for lightweight products without crosslap-per, the additional web profile regulation (VPR) provides further improvement.

Maximum flexibility during web forming

AirlayAirlay ensures maximum flexibility during web forming. The webs are formed by suction on a perforated roll, covering a large weight range. The low exhaust air output demonstrates the particular energy efficiency of Airlay – the air use is according to the actual requirement. Typical for Airlay is also the easy processing of waste fibers.

individuality as basis for success

Roller cardAt TRÜTZSCHLER NONWOVENS, individuality means that you can combine six different basic machine types with three different doffing sys-tems (parallel fleece, random roller, condensed roller). Plus there are various special machines. They adapt perfectly to your production situa-tion, regardless of what you intend to produce. At the same time, our roller cards have impor-tant things in common. This includes extremely clean take-off system, specially adjusted TCC clothings and excellent maintainability due to optimal accessibility.

Our specialist for web entangling technology

Random cardOur special roller card for random web technol-ogy is particularly well suited for subsequent hy-droentanglement. It allows a high random layer, while at the same time offering large variability in web weight. The fact that it only requires two different roll diameters - which in turn greatly reduces clothing change - is a clear advantage. All in all an unequalled performance package.

Triple performance

Airlay roller cardOur Airlay roller card, whose card section ensures an optimal opening, forms a homo-geneous random web in the adjacent Airlay head. It only takes three different roll diameters to achieve high performance and first-class precision. At the same time it is very compact, requires only a few clothings, is easy to clean and allows a large weight range.

The erko Airlay roller card delivers first-class results at minimum space requirement with just three roll diameters.

Precision layers

Web layer edges positioned precisely on top of each other result in reduced edge trims and thus optimal material utilisation

CrosslapperDepending on working width, the crosslapper processes over 160 m web per minute. The profiled and quick web lapping goes hand in hand with high lapping accuracy. Interfering fac-tors, such as air flows and centrifugal forces, are eliminated - even difficult materials can be proc-essed at high speeds. The quality is continuously optimised by a special software: It measures the bonding result over the entire working width and, if necessary, adjusts the weight at the belt weigher prior to web forming. This always produces the desired end result. A defined draft zone at the outlet of the web replaces the previ-ously known floating draft zones. This offers the advantage of profiling the laid down web precisely at the point where optimal adjustment of the cross section is possible.


Quick drafting

Drafting zones: 4 – 8


erko web drafter

By changing the fiber orientation, the erko web drafter achieves an ideal MD/CD ratio.

erko roller card installation with high performance crosslapper

Web drafterWith up to eight drafting zones, our web drafter impresses during material drafting – fiber-oriented in machine direction – with up to 30% increase in line speed when processing light-weight products.

Capacity: over 160 m/min.

Folding width: < 8.000 mm

Number of layers: 4 –76 layers

new belt path reduces oscillating masses

Another special feature of the crosslapper is its low energy consumption: A systematic reduction of the moving machine masses and all rolls made of carbon fiber reinforced plastic (CFRP) lead to reduced acceleration and braking performance. The result is an increased energy efficiency that is even further improved by AC servo motors with energy recovery.

Web guidance: lay-down with defined draft


Modular efficiency

Hydroentanglement: AquaJetOur AquaJet hydroentangling is available as modular system, ranging from "Mini" to "Jumbo". The number and position of water beams are freely selectable to meet your individual product or material requirements. Thus, the AquaJet ensures super quick and efficient web bonding and also offers the additional function of structur-ing and/or perforation. Other convincing features are its maintenance und user friendliness Hence, it is no surprise that our customers applaud it for being a system with highest product availability.

As additional function, structuring and/or perforation are available.

Steam jet bonding: SteamJetFor water-sensitive fibers as used in the production of hygiene products and wipes, our SteamJet combines the advantages of the AquaJet with those of a "dry process". Steam generation requires only very small amounts of water, thus eliminating the need for expensive water treatment. For bonding and/or structuring of fibers, the SteamJet requires only one single step, not several. This results in high perform-ance and speed.

versatile advanced technology

NeedlingOur needling machines impress with their tech-nology and versatility. Thus, you can select the ideal solution for needling in all directions from five machine types The patented swivel bearings are a technical highlight: In contrast to conven-tional bearings, they are absolutely free of wear and maintenance. This results in lower operating costs and higher productivity. A reliability that has set new standards even during 24/7 operations and an open and therefore easy to access design are additional advantages.

For processing special materials, a suction system is available which - in combination with a compressed-air pulse - keeps the critical areas of the machine clean. The simple and reliable air cooling of the conrod main bearings is equipped with special filters that ensure adequate cool-ing even in case of long maintenance intervals and prevent contamination of the drive system. A central minimum quantity lubrication supplies all main bearings of the double-shaft system in selectable intervals with a specified amount of lubricant, thus preventing contamination of the machine in the drive area.

Patented, wear-free swivel bearings reduce maintenance and thus operating costs.

Edge openerThe EROE can be applied inline as well as offline and is used for opening web waste. This waste can be returned into the ongoing proc-ess, thus significantly increasing the system's efficiency. The edge opener has a compact design, featuring a feed system and high-speed tearing rollers equipped with needles or cloth-ing. The edge opener is generally available with two different feed systems. With roller feeding (WEZ) it is suitable for recycling of thermally bonded webs and needle felts up to 2000 g/m².The version with tray feeding (MEZ) is used with hydroentangled and chemically bonded webs up to 1000g/m². Optionally, a spraying device is available.

Oven technologies for highest demands

Through-air flow and jetting

Fleissner belt oven

The optimised insulation offers high energy efficiency and economic operation

Since energy efficiency is an important aspect in oven technologies, we have "frozen" the heat loss of our belt and drum ovens at lowest level by means of a perfectly calculated insulation.

Thermal bonding via belt ovenFor the production of voluminous high loft prod-ucts, our belt oven offers the best solution. A high level of temperature accuracy and optimal flow over the entire width produce a very uni-form bonding.

Thermal bonding via drum ovenThe through-air principle creates a suction draft on the drum surface which safely keeps the web on the drums; at the same time air flows through the web. High speeds are achieved when processing lightweight to medium weight products; 1 to 10 drums are possible in series.

Perfect impregnation

ImpregnatingFor our impregnating methods we prefer foam foulards, which reduce the use of chemicals and at the same time the drying requirement. Even heavy webs can be completely saturated with minimum application of foam and energy. This is another contribution to increased efficiency through energy reduction.

Smoothening/calibratingDuring smoothening and thermal stabilisation of webs, our systems engineering creates an ab-solutely uniform line pressure, while the heated and/or cooled systems ensure high tempera-ture uniformity. Best conditions for technically sophisticated web material at constant high quality.

HeatsettingThe advantage of our heatsetting concept be-comes quickly apparent when comparing it to a conventional two-roll calendar Needle rings hold the web in place along the width. This prevents the material from shrinking within the defined setting zone. At the same time the through-air principle ensures uniform web setting.

As in the Precursor Lines the overall process control is completely visualized for quick and easy access to all relevant machine and process parameters.

Since high qualities and efficiencies depend much on defined tensions at each point of the line, this conveying system plays a key role in the process beside the oxidation and carboniza-tion technology.
