In a general metal pressing line, when a metal coil is running out, it will need to stop the stamping process, and load a new metal coil.
When load a new metal coil, a coil car lifts the metal coil to the same height of uncoiler mandrel, then we need centering the metal coil to the decoiler mandrel and use coil hold-down arm and limiting device to set up.
This coil feeding line has a dual decoiler part. The two decoiler mandrels are in opposite directions, with a rotating structure to switch.
When one side decoiler is working, the other side can load the coil, which will reduce the coil loading time and increase the metal pressing productivity.
