The roll 70 loaded on the conveying unit 50 is supplied to the processing machine.

[30] A chain 34 is disposed at a facing side of circumference of guide rail 30 that faces other guide rail 30. Such a chain 34 is guided by a teeth shaped wheel 62 of a first rotator 63 shown in FlG. 7 so that the guide rail 30 is rotated thereby.

[31] As shown in FlG. 8, the sub guide rail 40 is formed in a shape of circle, and a pair of rails is connected through a second connecting frame 42 as a center to configure the sub guide rail 40. A plurality of sub-guide rails 40 is disposed inside the guide rail 30 and is supported by the second support roller 35 disposed at the guide rail 30. At the circumference of sub-guide rail 40, a protrusion 43 having a shape of ' τ= ' is formed as shown in FlG. 9. The second support roller 35 is contacted to the circumference of sub guide rail 40 through the curved portion of the protrusion 43. Also, a chain 44 is disposed at the outer side of protrusion 43. The chain 44 is geared with a teeth shaped wheel 62 of a second rotator 64 to guide the sub guide rail 40 to be rotated as shown in FlG. 10.

[32] Herein, two teeth shaped wheels 62 are included in the first rotator 63, and one teeth shaped wheel 62 is included in the second rotator 64. It is because the chain 44 is only disposed at one side of sub-guide rail 40 and two chains 34 are disposed at both sides of guide rail 30 facing one another. However, the teeth shaped wheels 62 of second rotator 64 may be prepared as two if the chain 44 is disposed at both of sub-guide rails 40 which face one another as like as the guide rail 30.

[33] A second roll housing member 41 is disposed inside of the sub-guide rail 40. The second roll housing member 41 is formed in a shape of circular belt. The second roll housing member 41 is disposed at inner circumference of each sub-guide rail 40 as shown in FlG. 8 differently from the first roll housing member 31. Therefore, end portions of roll 70 housed in the second roll housing member 41 are only contacted and supported by the circular belt shape of the second roll housing member 41. The roll 70 becomes released from the second roll housing member when the second roll housing member is located at a bottom center position of the sub guide rail 40 and loaded on the conveying unit 50 to be supplied to the processing machine.

[41] In order to supply the roll 70 housed in the roll housing members to the processing machine, the roll 70 is discharged to the third conveyer 53 thrαgh the second conveyer 52. In order to supply a target roll 70:A having a proper size to the processing machine as shown in FlG. 12, the rotating unit 60 rotates the guide rail 30 as shown in FlG. 13. When the target roll 70:A is located at the bottom center position, the second conveyer 52 is driven to discharge the target roll 70:A from the first roll housing member 31 as shown in FlG. 14. At the same time, a new roll 70:C is continuously housed to the first roll housing member 31 using the first conveyer 51.

[42] In order to supply a roll 70:B housed in the second roll housing member 41 to the processing machine, the sub guide rail 40 is rotated using the same method of rotating the guide rail 30. In more particular, the sub guide rail 40 is rotated inside the guide rail 30. At first, the sub guide rail 40 housing the target roll 70:B is located at the bottom center position by rotating the guide rail 30 as shown in FlG. 15. Then, the target roll 70:B is located at the bottom center position of the sub guide rail 40 by rotating the sub guide rail 30 as shown in FlG. 16. After rotating, the second conveyer 52 discharges the target roll 70:B from the second roll housing member 41 to the third conveyer 53. In order to fill the second roll housing member, a roll 70 :D is supplied to the second roll housing member 41 by the first conveyer 51.
