Electronic Jacquard Machine Operation and Hook Systems
topic
Electronic Jacquard machines actuate individual hooks connected through harness cords to individual warp ends using electromechanical or electromagnetic actuators controlled by digital signals decoded from the design programme, with each hook raised or lowered independently for every pick according to the binary pixel value at the corresponding design point, enabling the translation of digital fabric images into physical warp raising sequences at weaving speeds of 200 to 400 picks per minute.
Role
Provides the individual end control mechanism that translates digital design data into woven fabric by physically raising or lowering each warp end according to its design programme, with electronic Jacquard replacing mechanical needle-and-card selection that limited pattern speed and required physical pattern carrier preparation, with the direct connection between digital design files and electronic Jacquard control enabling the seamless digital workflow from design creation to loom production.
