Dobby types S2688 and S4080 for technical fabrics

Stäubli provides a complete range of dobbies and cam motions for manufacturing all types of technical fabrics. Completely customized solutions can be configured for specific requirements.

Rotary dobby type S2688

This high-performance electronically controlled open-shed dobby operates according to the Stäubli rotary principle. It can be installed on the weaving machine on either the right or left and in upper or lower position.

The following models are available:

  • Model S2688 S for high speed
  • Model S2688 RS for high warp yarn tension

 

Closed-shed dobby type S4080

This electronically controlled closed-shed dobby is particularly suitable for the manufacturing of wet felts, seam felts, dryer felts and forming fabrics. A high loading capacity and precise frame movement characterize this exceptionally compact dobby, which requires little maintenance. Its operation is both reliable and silent, even with high rotation speeds and high warp yarn tensions.

Owing to its compact and symmetrical shape, this machine offers a variety of possible installation configurations on the weaving machine. The dobby type S4080 can be equipped with an electronic monitoring device, which detects the frames during the entire raising movement in upper or lower shed position.
