The Si jacquard was developed to meet the demand for high hook capacity at high speed. Thanks to the development of the micro-selector, we were able to develop the fastest, lightest and most compact jacquard in its range, while maintaining the strength, stability and robustness typical of Bonas jacquards.
The Si series is extremely suitable for weaving all kinds of fabrics, including damask, airbags, silk, clothing, curtain fabric, upholstery fabric, lining, wall coverings,… The Si features meet the requirements of the customer: long life, low energy consumption, minimum maintenance, high performance, flexibility, high speed,…


Si3, Si5, Si7, Si9, Si11, Si14, Si16, Si18, Si21, Si19, Si25 and Si27

Hook capacity varies from 1920 to 27648 in a single jacquard!


All flat woven fabrics and technical fabrics.


  • Revolutionary drive mechanism specially developed to produce at high speed, heavy load and maximum flexibility.
  • Fully balanced double-sided cam drive
  • Direct drive with high jaw accuracy
  • Gap stop for longer insertion time, reduced gape angle for optimal weaving of each application
  • Optimal fine adjustment of the gape without skewing the jacquard


Unique micro-selectors, 100% electronic selection with full control and 100% diagnostics. Developed to operate in a dusty environment, maintenance-free and independent of temperature.


Bonas offers harnesses of the highest quality, tailor-made for all applications either for high speed or heavy duty.

The quick connectors are standard and offer great ease of use.

Super structure

Due to its compactness and low weight, the Si is ideally suited to be placed directly on the loom in certain cases. The jacquard stand is replaced by a much lighter and more compact "Super Structure". This Super Structure can be extended with a platform around the jacquard. It goes without saying that such an arrangement saves an enormous amount of space and money.
