SwissJet

HEBERLEIN. SWISSJET.

Features and Benefits.

The SwissJet is designed for the effective interlacing of multifilament yarns during false-twist texturing. The jet has a housing that is specially reinforced with carbon fibres which give it particularly great strength during operation, a long service life, and a very low weight. Various jet inserts are available for the different yarn types.

Assortment.

Series APe

The APe series enables significant air savings of up to 15%. Existing jets can be replaced within seconds thanks to the 'plug & play' design. While the jets help to minimize the cost-intensive 'compressed air' resource, no compromises are required in terms of yarn quality. The investment pays for itself within a very short time.

Series APh

Designed to ensure maximum knot stability for downstream processes, such as weaving. A comprehensive series of tests have shown that up to 100% stability can be achieved at a load of 1 cN/dtex. This allows higher machine speeds and results in increased productivity. Alternatively, the sizing application can be reduced, which has a positive impact on costs and the environment.

Series P

The comprehensive P series covers a wide range of applications. Whether a light interlacing density with low stability is required, a strong interlacing density, high stability or microfilament yarns are processed - the variety of available jet types offers the right, cost-effective solution. Due to the very tight tolerances, this series offers a high uniformity from position to position. Customised types are available on request.

Series S

The cost-effective alternative to the P series with a scaled-down range of jet types.
