Electronic Jacquard machine Ji

for weaving machinefor loom

Overview
The Ji jacquard is built on the micro-selector concept and integrates a compact, balanced double-cam drive. Available with 1920 to 17280 hooks in a single unit, the Ji is designed for low power consumption, minimal maintenance and long service life while offering high flexibility for a wide range of fabrics.

Key benefits

• Optimal flexibility
• Design freedom
• Future-proof architecture

Design & Performance highlights

• Modular, compact construction
• Wide design freedom for patterning
• Ideal harness angle for improved shed formation
• Low energy consumption
• Direct mountable on a loom superstructure

Unique benefits

• Upgradeable, future-oriented development path
• Low power consumption
• Minimal maintenance requirements
• Long lifetime components
• High operational performance
• High flexibility across fabric types
• Suitable for heavy-load applications

Selection mechanism
The Ji uses a 100% electronic micro-selector derived from proven designs. It provides full control and diagnostics, is temperature-independent, maintenance-free and well suited to dusty production environments. The compact selector contributes to one of the lightest and fastest jacquard heads in its class while maintaining stability and strength.

Drive mechanism — driven by experience
The Ji features a fully balanced double-cam drive developed for high-load production and maximum flexibility. Key attributes include:

• Fully balanced double-cam configuration
• Fewer and lighter moving parts to reduce friction and vibration
• Low center of gravity to minimize jacquard and gantry oscillation
• Self-lubricating components to reduce maintenance

Dwell
The integrated dwell setup lets the Ji adapt dwell duration per loom width and application. Optimizing shed angle and insertion time reduces yarn stretch, improves weaving efficiency and enables larger dwells without sacrificing speed due to the mechanism's reduced inertia.

Harness
BONAS harnesses are offered for jacquard weaving, with designs informed by velvet and carpet harness production. The BONAS iS harness is engineered for heavy-load testing and to weave materials from silk to technical textiles with consistent performance and efficiency.

Controller (Ce controller)
The BONAS Ce controller is a Linux-based jacquard controller providing an intuitive interface via a 10.4" color touchscreen with icon navigation. Pattern transfer is supported by USB or network with bi-directional communication. The controller is Industry 4.0 compliant.
