  • the piston rod 8a of the hydraulic cylinder 8 is extended synchronizing with a coiling start timing of a tip of the metal strip 3, which is obtained on the basis of the signal from the laser sensor 9 and, by this, the support frame 7 is rotated by a predetermined angle in the direction approaching an outer face of the mandrel 2, thereby sandwiching the tip of the metal strip 3 between the wrapper roll 6 and the mandrel 2.
  • the support frame 7 is rotated by a predetermined angle in the direction separating from the outer coiling face of the coil 5 by retracting the piston rod 8a and, by this, the wrapper roll 6 is caused to wait at a predetermined position by being shunted from the outer coiling face of the coil 5 until a predetermined time before the coiling is finished.
  • an extension/retraction amount of the piston rod 8a of the hydraulic cylinder 8 in this case is controlled such that a detection angle obtained by the rotation angle detecting sensor 12 agrees with a rotation angle (this is stored in a storage area of the control section 18) of the support frame 7, which is previously set in compliance with a sandwiching position of the metal strip 3 tip and a shunting position at the wrapper roll 6.
  • the aforesaid step portion 16 appears in the coil 5 outer coiling face between the wrapper roll 6 and the mandrel 2 correspondingly to the step between the most tip portion (metal strip tip) 5a of the metal strip 3 and the surface of the mandrel 2.
  • the coiling finish stage on the basis of a tail end wrapper roll pushing start signal from the strip shear controlling unit 20, first, when starting a pushing by the wrapper roll 6 against the coil 5 outer coiling face, it is judged whether or not the position ⁇ , of the metal strip tip portion, operated by the operation section 17 on the basis of the signals from the laser sensor 9, the rotating speed detecting sensor 10 and the sheet speed detecting sensor 11 agrees with a contact position, stored in the storing section 19, of the wrapper roll 6 with respect to the coil 5 outer coiling face.

  • an extension/retraction amount of the piston rod 8a of the hydraulic cylinder 8 in this case is controlled such that a detection angle obtained by the rotation angle detecting sensor 12 agrees with a rotation angle (this is stored in a storage area of the control section 18) of the support frame 7, which is previously set in compliance with a contact position and a shunting position with respect to the outer coiling face of the coil 5 at the wrapper roll 6.
  • a pushing force per a coil width 1 m of the wrapper roll 6 with respect to the outer coiling face of the coil 5 is made a range of 10 - 20 kN/m. If the pushing force is lower than 20 kN/m, a braking force necessary for a rotation of the coil is not obtained and, further, it is impossible to suppress a bulge of coil outer periphery portion owing to a centrifugal force at high speed rotation time. On the other hand, if it exceeds 20 kN/m, a high pressure is generated when the wrapper roll 6 impinges against the step portion 16 of the coil 5 rotating at high speed, so that a center buckle occurs in the coil 5.

  • the piston rod 8a is retracted such that the detection angle obtained by the rotation angle detecting sensor 12 agrees with a rotation angle, of the support frame 7, previously set in compliance with a shunting position of the wrapper roll 6, thereby rotating the support frame 7 in the direction separating from the outer coiling face of the coil 5 and, by this, the wrapper roll 6 is shunted from the outer coiling face of the coil 5 until a predetermined time before the coiling is finished, thereby causing it to wait in a predetermined position.
  • this waiting position it is advantageous to locate it as nearly to the mandrel as possible than a open limit of the wrapper roll, because an operation for pushing the wrapper roll at a coiling finish time can be rapidly performed.
  • the piston rod 8a of the hydraulic cylinder 8 is extended synchronizing with the previously set pushing start timing such that the detection angle obtained by the rotation angle detecting sensor 12 agrees with a rotation angle, of the support frame 7, previously set in compliance with the contact position with respect to the outer coiling face of the coil 5 at the wrapper roll 6 in order to brake the rotation of the coil 5 to stop it in a short time and, by this, the support frame 7 is rotated in the direction approaching the outer coiling face of the coil 5, thereby bringing the wrapper roll 6 into contact with the coil 5 outer coiling face.
