F ollowing are some of the most recent developments in the field of weaving machines and accessories, destined to increase weaving mill productivity, while at the same time achieving significant savings in labor and energy.
Lindauer Dornier GmbH, Germany, used this year's International Textile Machinery Trade Fair (ITMEX Americas) 2005 in Sao Paulo, Brazil, as a platform to emphasize its drive in technological progress. New developments cover the complete weaving machine product line. The new performance generation of air-jet and rapier weaving machines; and the ServoTerry® machine for terry weaving are complemented by innovative advances in leno technology with the EasyLeno® weaving machine for technical and decorative fabrics.
ServoTerry is used in the home textiles sector. Its advantage over existing systems is its direct drive for terry movement using a servomotor while retaining precise but gentle reed impact. This allows varying pile weave and adjustable pile heights during operation. The 260-centimeter (cm)-wide machine is equipped with a Staubli dobby with 16 shafts for the production of three-width terry bath towels at varying speeds of 540 and 600 revolutions per minute (rpm).
Other developments include the AS air-jet weaving machine, which runs with new, patented ServoControl® pressure regulation. This minimizes thread load and allows automatic, reproducible pressure adjustments for yarn lot changes to be made, and ensures higher performance with improved final fabric quality, according to Dornier.
Another recent development is the AirGuide® patented air cushion guide for Dornier rapier weaving machines. The linear movement of the rigid rapier rod is ideal for this new system - the perfect technical solution for contact-free, aerostatics support.
The EasyLeno system for rapier and air-jet weaving machines enables up to 100-percent higher performance in leno technology, and opens up options for completely new fabric design in the technical textiles and home furnishings sectors.
Jakob Muller AG, Frick, Switzerland, offers weaving machines for the production of patterned elastic and non-elastic narrow fabrics and lace articles, including satin ribbons and tapes. Its needle weaving machines include models such as the NF, NG and Varitex V5Ni.
The company has improved the NF model, which now is able to insert up to six weft colors, substantially increasing weft pattern options. The choice of weft colors is practically unlimited. Length changes are achieved by electronic single heddle control, programmed and controlled via the Mudata system.The NG3 model is equipped with a Quick-Style-Change system for reeds, heddles, drop wires and heddle frames; this option also is offered for the warp frame beam. The NG3 is designed to provide optimum performance for belts, and non-elastic and elastic fabrics.
Picanol NV, Belgium, manufactures several kinds of high-tech weaving machines for different applications in the textile industry. The OMNIplus air-jet machine for the weaving of staple fibers, filament, high-twist yarns, elastic yarns, chenille and texturing yarns, among others, uses up to six colors and different types of fillings.The OMNIplus comes in reed widths of 190, 220, 250, 280, 340, 380 and 400 cm. It can produce fabric rolls 720 millimeters (mm) wide, or up to 1,500 mm wide with Picanol's separate Picanol Batching Motion system for rolling of fabric.
Other advantages include digital adjustments and synchronization of the complete weft insertion cycle; a separate frame for style change in less than 30 minutes; a high level of weft insertion performance, allowing more weaving using less air; rapid change of the roll and the warp; low construction with ergonomic characteristics; and a Sumo main motor for the direct drive of the machine.
Picanol's OMNI plus air-jet weaving machine is available in a variety of reed widths.
Promatech S.p.A., Italy (formed by the merger of Somet and Vamatex), is a member of the Itema Group, also based in Italy.

The Delta automatic drawing-in machine is known throughout the world and has demonstrated its capability in many diverse applications. One of the main advantages of this system is the reduction of labor costs owing to automation and rationalization, with great flexibility to adapt to varying needs of the market.The Topmatic tying machine guarantees maximum efficiency during the warp change process. The use of all yarn types and optimum tying quality lead to minimum downtime.Stlis Warplink warp welding device enables the laying-in and start-up weaving of newly drawn-in or stationary tied warps to be accelerated and simplified. The company reports resultant time savings at style change may exceed 30 minutes.
Staubli's Topmatic tying machine helps makethe warp change process more efficient.
