Abstract
PURPOSE:To hold the position of an expanded drum of an uncoiler at an optional position, by detecting the position of a rotary cylinder, and by controlling this position of the rotary cylinder. CONSTITUTION:If the uncoiling process comes to an ending stage, and the residual number of turns of a coil 1 becomes small, the slip of a drum shaft 3 against the coil 1 gradually increases because of the reduced friction force between the drum shaft 3 and the coil 1. With this increase of the slip, a piston 11 of a rotary cylinder 10 also displaces. This displacement of the piston 11 is detected by a differential transformer 14 whose output is sent out as a feedback to a hydraulic circuit which then automatically controls the output pressure of a pressure control unit 15. Hereby, the oil pressure is controlled so as to always keep the diaplacement of the piston 11 due to the reduction of the number of turns through an uncoiling process at a prescribed position, so that the coil layers do not cause mutual slip and the coil 1 is not injured; as a result, a good uncoiling process is performed.
