Top performance and maximum efficiency

Machines from the Jakob Müller AG’s NG3 series are the world’s fastest narrow fabric needle looms and an NG3S 2/66 S5 for medium-weight belts will be in operation at the Techtextil.

The NG3 series of narrow fabric needle looms represents a technical and technological development quantum leap. The heald frame drives and movement, as well as the shafts and healds are designed for high speeds, and for medium-weight articles now offer a maximum of 2,750 min-1 (using the S5 weaving system). One of the main reasons for this high performance is the new, wear-resistant NGV3 harness. In tandem with top quality raw materials, weft thread guidance, compensation and monitoring guarantee first class product quality and reduced standstill times. The patented compound needle system is characterised by the safe, low-tension insertion of the threads. 

This results in increased efficiency and a simultaneous reduction in knitting needle breaks. Moreover, the NG3S version of the machine (the “S” stands for “silent”) is fitted with additional noise protection, which cuts emissions by as much as 10 db(A).

The NG3S 28G 2/66 S5 offers the following advantages:

  • High production performance with speeds of up to 2,750 min-1
  • The possibility for speed changes while the machine is running
  • Excellent machine efficiency in combination with low wear and a minimum maintenance requirement
  • Patented, air-sprung heald motion for high speeds
  • Extremely reliable and reproducible narrow fabric quality with selvedges of a very high standard
  • Simple and clear operation and control
  • Outstanding machine and operator safety

To documentation

NG3 product samples

The belt to be shown at the Techtextil 2019 will consist of a warp composed of a 100% PES filament with a 1,670 dtex yarn count and a weft formed by a 550 dtex PES filament. Selvedge formation takes place using the 5 weaving system, whereby the auxiliary threads have a yarn count of 280 dtex and the locking threads 113 dtex. The special weave provides a combination of excellent filament strength use and an attractive, glossy product appearance, which is especially advantageous during employment as a lifting belt. Proven tear resistance of 29.8 kN with 6.83% elongation is a high value that represents a 16% increase over standard belts. Apart from lifting, the belts can also be used in nets to secure aircraft cargo.  

The versatile Multiaxial/EL-32

This electronically controlled, RR-knitting machine (double knit) from Comez is ideal for the production of technical, multi-axial knits.

The Multiaxial/EL-32 knitting machine with a 32 inch-wide needle bed is characterised by the following features:

  • Simple handling
  • Robust design
  • A compact superstructure
  • Fast article changeovers due to reduced needle bed width
  • Gentle knitting tool movement
  • Photoelectric sensors for optimum accident protection

The EL-32 can employ a wide range of raw materials:

  • Carbon (CFRP, carbon fibre reinforced polymer)
  • Glass (GFRP, glass fibre reinforced polymer), known in Italy as (PRFV, polyester reinforced with glass fibre)
  • Aramid (AFRP, aramidic fibre reinforced polymer, e.g. Kevlar®)

Multi-axial knits represent complex textile structures, the potential of which can be used to the full with the EL-32. The electronic control of the thread guides and the knit take-off enables the use of differing stitch densities (stitch rows/cm) and elasticity values in the same article. Moreover, different weft and warp threads can also be introduced.

Die MULTIAXIAL/EL-32 ist zudem mit einem DATA CONTROL CONTROLLER ausgestattet, welcher eine neue Generation von Aktuatoren mit ausgezeichneter dynamischer Kennlinie und hoher Positioniergenauigkeit antreibt. Der CONTROLLER ermöglicht die Steuerung aller notwendigen Funktionen, überwacht die Produktionsdaten und erlaubt lange Musterrapporte, bis zu einer nahezu unbegrenzten Anzahl an Maschenreihen.

Das Design und die Programmierung des Musters erfolgen mit der Textilsoftware COMEZ DRAW 3 oder SYSTEM.WIN für PC’s. Die Musterdaten werden vom PC über einen USB-Speicher zum DATA CONTROL CONTROLLER übertragen.

Non-elastic shoe laces

Laces that come undone when one is walking are a frequent source of annoyance and in addition, can create dangerous situations that lead to tripping and falls. Therefore, the idea underlying the development of the 10310 sample was to create a shoelace with a narrow-wide-narrow effect, which would render unwanted loosening impossible. The sample was produced on an NFJM2 53 6/42 narrow fabric needle loom with an electronic drive (ED) function. Weft guidance using an ED enables precise weft length control and by means of a reduction in input quantity, the shoelace contracts thus creating the desired structure.

Non-slip cord

This elastic cord, which was manufactured on an NH2 53 8/27 narrow fabric needle loom, is designed for a diversity of applications. As a modish shoelace in sports shoes, the non-slip cord quickly attracted fans amongst fashion-conscious youngsters. What’s more, it can also be employed for outerwear as a hood drawstring. The bulges and constrictions are produced by means of the electronic control of the weft and a special weave. In addition, the use of a highly elastic yarn creates a pleasantly soft feel.

Rucksack tapes / shoelaces

Rucksack tapes and shoelaces frequently have tapered ends with a sleeve, which in trade jargon are known as “tips” and are intended to assist threading though eyelets. In the past, the creation of this tapering always required an additional production procedure, but now the use of the NH2 53 6/27 SNO2B renders this unnecessary. Once the wide section of the weft thread 1 has been woven, the machine switches automatically to weft thread 2. This is fed in under increased tension and thus forms the tapering. Moreover, in order that the “tip” receives the required rigidity, a monofilament can also be employed as the weft thread 2 (sample 10350).

Lightweight belt with a combined warp-weft effect

As a rule, the patterning effect in jacquard narrow fabrics and tapes is only achieved in the warp direction. However, with the help of KSE technology, warp and weft thread and colour effects can be combined. For example, in order to create the 10374 sample, a weft selection device can be installed on jacquard machines such as the NFJK2 53 4/42 ED. Apart from the back weft this allows the insertion of up to three additional weft colours into the weave by means of the use of specially designed weft needles. An electronic drive (ED) guides the weft and two weft threads are introduced simultaneously, which further increases the possibilities for patterning and combinations.
