When sourcing a Staubli Jacquard machine, the primary focus should be on the electronic control system (e.g., JC8) and the hook capacity, which typically ranges from 1,440 to over 25,000 hooks. Ensure the machine supports the required RPM (Revolutions Per Minute) of your loom, as high-end models can exceed 1,200 RPM. Additionally, verify the harness type and quality, as the integration between the Jacquard head and the harness determines the precision of the fabric pattern and the longevity of the mechanical parts.
