Coil hold-down arm: Add pressure on the coil to avoid strip lose during uncoiling process
Coil hold-down arm material: Polyurethane rubber wheel, 180mm width
Coil hold-down arm drive mode: Motor-driven
Coil hold-down arm speed adjustment: Speed regulation (refined pulse) by angle encoder feedback signal
Coil guide limit arms: Coil guide limit arms have two rollers. The inside rollers have a fixed angle, and the outer rolls can be open or close by air cylinder drive. When the two rollers are closed down, the metal coil will be fixed between two rollers, to prevent loop misguide. After coil uploaded on the uncoiler mandrel, the two rolls will be moved with self-centering to meet the setting coil width. The two rollers are non-motorized with free rotation, and the surface is black phosphorus treatment.
