Features


Space-saving and high synchronization

This line combines the decoiler and straightener part, which saves the material loop space, and more importantly, it achieves the highly synchronize between uncoiling and straightening process.

Precision straightening performance

With 7pcs high-quality rollers, the combined decider straightener machine is capable of handling a variety of high precision straightening request. Moreover, the 15pcs rollers type is capable of handling the rigorous straightening requirements. And for some copper or aluminum material, it has operable straightening part for easy clean and maintenance.

For uncoilers, there's two expansion type for different coil weight range, manual expansion, and hydraulic expansion.

Main Parts & Description


Combined Uncoiler Straightener

Depends on different material type, there’re passive uncoiler as well as motorized uncoiler. Passive uncoiler will be suitable for general stamping process.

When the thickness is thin, and surface requirements are particularly high, a motorized uncoiler parts will be applied.

When the coil is springy type, a hold-down arm with pneumatic pressure will be suitable for this situation.

All the rolls are made by Gcr15 bearing steel, with surface thickening chrome grinding. And the pressure on straightening rolls is the pneumatic type with worm wheel adjustment, for precision and smoothly straightening process.
