Features of uncoiler straightener and feeder machine
Workspace Saving and Safety Operation
It combines decoiler, straightener, and feeder machine into one unit and controlled by a single touch screen. The advanced equipment configuration saves lots of workshop space. With an integrated control system, this decoiler straightener feeder is capable of a self-diagnosis system, which has maximum protection of the operator’s safety.
Wide Range of Applications
Uncoiler straightener and feeder machine GLK3 series has a broader range of appropriate material. It can process metal thickness from 0.5-4.5mm, coil width up to 1300mm. With quality straightening rollers and worm gear leveling adjustment, It can handle most of the stamping material, achieves a high precision straightening performance.
Smoothly Coil Threading Support
This uncoiler straightener and feeder machine series adopts adjustable coil guide rollers and pneumatic coil hold-up arm for smoothly coil threading. The pneumatic threading assists swing device prevents coil upwards, and leading material enters into straightener.
Precision Feeding Performance
With world-leading electronic control systems (Mitsubishi, Siemens, ABB) for feeding control and pneumatic pilot release to eliminate feeding tolerance, the material feeding accuracy can maintain +/- 0.1mm under 500mm feeding length.
