Then, the roll-shaped packaging sheet 1 is pulled out while being rotated by the support portion 15. In this case, by keeping the braking mechanism 18 in the braking release state, the roll-shaped packaging sheet 1 rotates without resistance and the packaging sheet 1 can be pulled out without trouble.

When the worker pulls out the packaging sheet 1 by a predetermined length as described above, for example, as shown in FIG.
Cut line 1b from roll-shaped packaging sheet 1 (see FIG. 3)
Is stopped, the withdrawal of the packaging sheet 1 is stopped and the braking mechanism 18 is operated to the braking side (see FIG. 2B). In this state, by pressing the cut line 1b of the packaging sheet 1 by hand or pulling the end portion of the packaging sheet 1 a little strongly, the packaging sheet 1 of a predetermined length is cut from the roll-shaped packaging sheet 1 to the cut line 1b. It is separated in parts. in this case,
Since braking is applied to the rotation of the roll-shaped packaging sheet 1, the roll-shaped packaging sheet 1 rotates and the packaging sheet 1 is pulled out when the packaging sheet 1 having a predetermined length is cut off by the cut line 1b. There is no such a case, and the separation operation can be performed without any trouble. By performing the above operation, the wrapping sheet 1 having a predetermined length can be separated from the wrapping sheet 1 wound in a roll shape. Therefore, the wrapping sheet 1 having the predetermined length is placed on the wrapping table 2 and the next wrapping is performed. Should be done. Then, the above operation is repeated every time one packaging is completed.

[II] When configured as in the above item [2], as in the case of the above item [1], the end of the roll-shaped packaging sheet supported by the support part is operated while the braking mechanism is in the braking release state. The person holds it and pulls out the packaging sheet while rotating the rolled packaging sheet on the support portion.

When the worker pulls out the packaging sheet 1 by a predetermined length as described above, the pulling-out of the packaging sheet 1 is stopped and the braking mechanism 18 is operated to the braking side, for example, as shown in FIG. In this state, when the packaging sheet 1 is manually pressed against the cutting portion 24 while the end portion of the packaging sheet 1 is slightly strongly pulled, the roll-shaped packaging sheet 1 has a predetermined length at the position of the cutting portion 24. The packaging sheet 1 is cut off. In this case, since the rotation of the roll-shaped packaging sheet 1 is braked, the roll-shaped packaging sheet 1 rotates to separate the packaging sheet 1 of a predetermined length at the cutting portion 24, and the packaging sheet 1 rotates. It will not be pulled out, and the detaching operation can be done without any trouble. By performing the above operation, the wrapping sheet 1 having a predetermined length can be separated from the wrapping sheet 1 wound in a roll shape. Therefore, the wrapping sheet 1 having the predetermined length is placed on the wrapping table 2 and the next wrapping is performed. Should be done. Then, the above operation is repeated every time one packaging is completed.
