Automatic Pre-punching C Z Purlin Roll Forming Machine

With Post-cutting Progress

• Quick C to Z interchange: The rollers for C & Z are changed very quickly

without dismantle any parts, The forming tooling is simply unclamped (two

bolts), rotated through 180 degree, and re-tightened. No tooling or spacers are

removed or changed. Quick, Easy, Simple.

• Size change: The form tooling is unclamped, slid into the correct position and

retightened. No special tools, no spacer changed. Infinite sizes are possible.

• Only input data in touch screen can adjust the any size automatically, by servo

motor driving stations moving accurately on linear guiderail with help of

encoder and limit switch.
