Abstract
The present invention provides an uncoiler apparatus capable of minimizing a waste amount of the total amount of coil, by reducing the damage to the surface of the coil caused by line contact between the coil and a drum when the drum expands to clamp the coil. The invention provides an uncoiler apparatus which includes: a stationary drum; a plurality of pressure cells rotatably disposed at an outer periphery of the stationary drum, the pressure cells being spaced radially along the periphery of the stationary drum and capable of individually expanding and contracting; a pressure applying unit that provides pressure to the plurality of pressure cells; a pressure regulator that regulates the amount of pressure supplied to each of the plurality of pressure cells by the pressure applying unit; a load detector that detects load of a coil wound about the plurality of pressure cells; and a controller that controls the pressure regulator on the basis of the load of the coil detected by the load detector to control the pressure supplied to the plurality pressure cells by the pressure applying unit.
