ITEMA AIRJET A9500
The airjet A9500 – the most innovative airjet weaving machine in the market – inspires the curiosity and sparks the interest from real technology buffs and has already amassed important references, especially in medical applications and automotive fabrics.
Looking at specific technical applications, the Itema airjet A9500 provides undeniable benefits, matching unparalleled performances and the highest productivity with superior textile efficiency.
The Itema A9500 is pre-set for independent motorized Jacquard with no cardan shaft, allowing to weave specific technical textiles (such as Airbag OPW) with no speed limitations.
When it comes to weaving very high density fabrics, the A9500 is customized with dedicated devices to ensure best-in-class results. Key components are reinforced to ensure optimized machine control and reliability whilst Itema patented devices guarantee reduced consumption and superior textile efficiency.
The reinforced whip roller eliminates friction allowing an improved warp tension control and reducing warp stops, whilst the left and right waste selvedge assures the correct tension of the weft leading to an excellent fabric quality.
Moreover, the longer dwell of the cam sley drive allows a longer weft insertion time, leading to a more efficient weft filling insertion. The Itema patented ELD – Electronic Leno Device, is the ideal solution for leno binding on high speed machines guaranteeing a perfect leno binding whilst significantly reducing operational costs thanks to its innovative design.
Itema is registering an increasing demand in airjet technology to weave fabrics for the automotive industry. Customers who chose the Itema A9500 to weave these type of fabrics, reported that in this particular field what makes the Itema airjet extremely successful is again the longer dwell of the cam sley drive and, a recent innovation featured on A9500, the double tandem nozzles which allow to weave even the most coarse yarns at high speed.
Parachute fabrics is another main application for airjet technology, and the Itema A9500 exceeds weaver’s expectations with its elastic whip roller, a dedicated device for warp tension compensation. The double pick insertion ensures to weaving ripstop and, furthermore, the Polito nozzle guarantees high speed weft insertion and unparalleled productivity.
