Mageba to unveil new shuttle looms at ITMA-2011

Mageba a specialist narrow fabrics machine producer is unveiling new high-productivity shuttle looms for manufacturing complex and multi-dimensional narrow fabrics at ITMA 2011 in Barcelona.

The new Mageba SSL MV shuttle loom is designed for complex fabric structures, such as multi-dimensional, multi-layer fabric for profile fabric and near net-shaped fabrics made of carbon fiber and glass fiber. This, brand new development increases the production output significantly and also makes possible the creation of new fabric weaves.

The loom on display in Barcelona, works with a 4-shuttle weft insertion, and is designed for light to medium-weight fabrics. The fabric width is up to 300 mm, and the weft insertion rate is up to 100 wefts per shuttle, per minute.

Shedding is done using a special jacquard of the type Unival 100, made by Stäubli. The 1064 harness cords of the jacquard are individually controlled by mini servo motors, and allow flexible, freely-programmable, warp thread-controlled shedding across the entire width of the fabric. This flexibility allows for generating several sheds at the same time, so that multi-shuttle simultaneous weft insertion is possible.

The combination of a servo driven weft insertion system, with four shuttles, a vertically and horizontally movable batten, and innovative shedding with harness cords controlled by servo motors allows simultaneous weft insertion of three shuttles, presently. This allows tripling of fabric production which up to now has never been achieved, compared to conventional weft insertion systems for shuttle looms.

In addition, using this machine configuration, new, multi-dimensional fabric structures with up to four varying weft thread materials can be developed, because each shuttle is equipped with varying weft yarn, and each shuttle movement, as well as the shedding, is individually programmable, per weft insertion.

Other features of the SSL MV shuttle loom are variable weft density, a V-reed for varying the width of the fabric, and an exchangeable take-off, to move profile fabric in a manner that protects the fabric.

Using a variable gap adjustment, the guide blocks of the shuttles can be adjusted to the fabric width, so that the weave angle of the weft thread, which can be set, has an optimal fabric edge. The use of servo motors optimally coordinates the machine movements, which means that, shedding opening times and material-dependent weft insertion parameters can be optimized.

Additional components for sophisticated and high quality fabric production, such as bifurcation regulated beam let-off systems, weft insertion monitoring, and weft spool winders can be obtained, as options.

To efficiently manufacture complex multi-layer fabrics, user-friendly weaving and visualization software is required. Working with the company ScotWeave, fabric development software for complex shuttle fabric is being developed and offered for sale, which supports the special characteristics and potential of Mageba multiple-weft and multiaxial shuttle looms.
