Electronic Jacquard Actuator Systems
topic
Modern electronic Jacquard machines use electromagnetic actuators where individual coils are energised or de-energised by the digital design signal for each hook position per pick, with the magnetic force deflecting or releasing a selection element that determines whether the knife raises the corresponding hook, with actuator response time below 5 milliseconds enabling operation at up to 600 picks per minute in high-speed electronic Jacquards, and with fully open architecture machines reading design data directly from computer memory without intermediate pattern carriers.
Role
Provides the electromechanical interface that translates digital design data into physical hook selection at production speed, with actuator response time and reliability being the technical parameters that determine maximum Jacquard operating speed and fabric defect rate from missed selections, with the evolution from mechanical needle-and-card to electronic actuator selection being the most significant technological advance in Jacquard history enabling both higher speeds and seamless digital workflow.
