7. Pneumatic system Double spooler

- Type: Semi-automatic dual spooler

-φ500/φ630 twin spooler is mainly used to draw copper wire of1.2mm3.5mm continuously with automatic bobbin change to get a continuous production.

- Wire traversing pitch is adjustable, bobbin loading & unloading, clamping and release are manually control by pneumatic system.

- Spool changing from empty to full automatically controlled by PLC, ensures spool changing successfulness up to 99.6%
