This year Staubli has produced Jacquard fabrics on four weaving machines at its ITMA Asia stand for the first time. As a noteworthy premier, Staubli demonstrated the production of lining fabric on the world´s most modern Jacquard machine, the type SX, in conjunction with a water-jet weaving machine operating at a rate of over 1,000 weft insertions per minute. The installation is equipped with a specific harness with 12,600 cords. A special feature of this setup is that the Jacquard machine is operated by an individual motor with synchronised drive.
Staubli developed this independent transmission principle, which can be combined with any type of Jacquard machine with any number of hooks. It enables special setups that are impossible with conventional transmission types such as shaft chains or belts.
The second installation is equipped with a type LX3202 Jacquard machine with 12,288 hooks and Staubli harness, weaving upholstery/tapestry fabric on a rapier weaving machine with 190 cm nominal width. Specialities of this unit are the 16 electronically selected weft colours and the capability to change the pattern on the fly, which means without stopping fabric production. The Staubli LX 3202 Jacquard machine is built for high speed and greater load capacity. It can be equipped in a range of 6,144 to 18,432 hooks.
The third Jacquard installation consists of a rapier weaving machine and a type SX electronic Jacquard machine with 2,688 hooks and a Staubli harness of 13,450 cords producing 220 cm wide upholstery fabric for car seats with six repeats.
And the fourth is also a type SX electronic Jacquard machine with 2,688 hooks and Staubli harness of 6,000 cords weaving car seat fabric 190 cm in width on an air-jet weaving machine operating at approximately 1,000 weft insertions per minute.
Type SX Jacquard machines are extremely versatile for broad use in modern Jacquard weaving. The machine is more compact and offers higher performance. Its nearly vibration-free drive mechanism requires a minimum of maintenance. Its sister model, the Jacquard machine type SX V, is used for the production of velvet fabrics. In this model the machine is equipped with 2,688 hooks driven by the M6.2 three-position module.
A type DX Jacquard machine including harness was shown at a special demonstration stand. The DX is suitable for any standard Jacquard application and can be used with the full range of Staubli harness types. Staubli harnesses are widely appreciated by weavers for their levelling features and the perfectly balanced quality of the components, which delivers high performance and durability.
At another demonstration stand, the LX32 type Jacquard machine with servo-motor drive mechanism for weaving narrow fabrics such as ribbons and labels was shown with 192 hooks and harness with 4 repeats. Like other Staubli Jacquard machines for narrow fabrics, the LX32 is programmed through the JC7N operating console. Thus all design options are left open.
S3000/S3200 electronic rotary dobby family: The rotary dobby, a revolutionary machine invented by Staubli many years ago, has been steadily developed further. The third generation of electronic rotary dobbies, the S3000/S3200 electronic rotary dobby family is to be seen with many application examples at the Staubli stand and at those of many other weaving machine manufacturers.
The new evolutionary principle with a new locking system features enhanced security for the selection of the heald frames, allowing higher running speeds as well as superior reliability. Thus the S3000/S3200 generation brings astounding benefits to weavers.
