PURPOSE:To correct the twisting of a cylindrical bag body simply by expanding and holding a part of a proceeding soft cylindrical bag body and detecting the twisting of the cylindrical bag body in the front of the holding part for rotating the cylindrical bag body of the holding part reversely to the detected twisting. CONSTITUTION:A soft cylindrical bag body, for example, a fire hose 18 is at first pushed into an introduction port 44, shaped to be oblong through guide rollers 41 and 40, and sent to a suction roller 27. Then, a penetration hole 15 is closed by a lid 17, and pressures inside a concave groove 3 of a casing 2, a pressure-reduction chamber 21, and a suction pipe 29, are respectively reduced by the suction work for absorbing the hose 18 to a rotor 37. Subsequently, the hose 18 is sent into a cylinder body 47, and the penetration hole 15 is opened to reduce the pressure in a hollow part between an inner wall 14 and the hose 18. After the hose 18 is expanded and a rod 19 is made to bite into the peripheral face, the hose 18 is rotated together with a rotary drum 4. When a colored line on the hose 18 is slided as it passes through a twist-detecting device 45, the rotary drum 4 is rotated reversely to the detected twisting for correcting the twisting. |
