摘要：<p>PURPOSE: An apparatus for preventing inner coiling part of coil product from unwinding is provided to prevent drop of actual yield and improve quality of coil product by closely adhering the inner coiling part of coil product to the inner surface of coil, thereby preventing the inner coiling part from unwinding. CONSTITUTION: The apparatus comprises a main body(30) comprising two or more grooves arranged circumferentially on the same radius around the center of the main body with being spaced apart from each other in an equal distance, longitudinally penetrated into the main body(30) and formed lengthwise in a radius direction of the main body(30); rods(60) inserted into the grooves so that the rods(60) are axially rotated and moved along the grooves; a body of revolution(50) comprising blades which are rotationally mounted on the central part of an end part of at least one side of the main body(30) and push the rods(60) respectively to move the rods(60) along the grooves when the blades are rotated; and a driving motor(80) for rotationally driving the body of revolution(50), wherein gear is fixed to the rods(60), and screw thread is formed on the blades of the body of revolution(50) so that the screw thread is connected to the gear with being engaged with the gear.</p>
