    • PURPOSE:To shorten the cycle time of work by a method wherein a first base arm and second base arm for a frame body fundamental shaft are integrally turned and elevated, and the revolving center of an outer peripheral paper roll arm and outer peripheral paper clamp arm is adjusted to meet the center of a coil, and speeds of the outer peripheral paper clamp arm and a cradle roll are synchronized. CONSTITUTION:A metal coil C is placed on cradle rolls 42-1, 42-2 which are provided in parallel. Also, the cradle rolls 42-1, 42-2 are driven in the same direction. On a frame body 50, a fundamental shaft is provided in parallel with the cradle rolls, and the fundamental shaft has a base 51 and is able to rotate. A first base arm 52 and second base arm are projected from the fundamental shaft, and an outer peripheral paper roll arm is axially supported by the first base arm 52, and an outer peripheral paper clamp arm is axially supported by the second base arm. After the revolving center of the outer peripheral paper roll arm and outer peripheral paper clamp arm has been positioned at the center of the coil by the rotation and elevation of the base arms, when an outer peripheral paper is wrapped around the metal coil C, a roll of the outer peripheral paper is made to revolve around the coil while giving self-revolving. After the outer peripheral paper has been wound to its rearend, pressure is added in the roll to expand a cushioning chamber, and a tape is pressed to strengthen the adhesion.

    • PURPOSE:To make possible to wind up an outlet peripheral paper without trouble even when the paper has the cohesive part of a tape on the outer periphery, and also make possible a strong application of a tape after the completion of packaging by a method wherein a winding-up of a packaging paper is started by drawing the paper end of an outer peripheral paper by vacuum by swelling or shrinking a buffer chamber which communicates with an air suction/removal system, and a winding-up of a second layer of the paper is performed under a shrinking condition of the buffer chamber. CONSTITUTION:A groove 32, which is provided in the axial direction of a roll 30, is covered by a rubber film 33 to form a buffer chamber 34, and fine holes 40, 41 are bored on the bottom part of the groove 32 and the rubber film 33. A winding-up of an outer peripheral paper 35 is performed while an adhesive tape 36 has an adhesive part 37 on the end part of the outer peripheral paper 35. When pressure in the roll 30 is reduced, the buffer chamber 34 shrinks, and under this condition, the paper 35 equipped with the tape 36 is drawn by suction. At this time, the cohesive part 37 is drawn by suction in the groove with a space and does not come into contact with the outer peripheral paper to be a second layer, and the roll winds up the paper by the self rotation. In order to place the outer peripheral paper 35 on a metal coil C, the roll 30 is revolved around the coil while rotating on its own axis. After winding the paper up to the rear end, the pressure in the roll is increased, and the buffer chamber 34 is made to swell to press down the tape 36.
