Further, the lateral dimension of the hanging portion of the rectangular wrapping material which is hung down by being covered by the left and right hanging type main body 2 does not necessarily have to be equal.

After the rectangular wrapping cloth is placed on the left and right hanging type main bodies 2 with the back surface facing inside, the operation of the inverting device is started. First, either of the left and right hanging type main bodies 2 is covered with the rectangular wrapping material A. The one that is finished is advanced to the center of the base 1 by the left and right drive device 3, and when it reaches the center of the base, which is the forward limit of the left and right drive device 3, the pressing device 7 operates to receive the signal and hang it to the left and right. At the same time as pushing down the approximately center of the upper side D of the rectangular wrapping covering the mold body, the air discharge device 6
The hanging-type lifting device 4 is activated, and the left and right hanging-type main body 2 starts rising. Then, as the left and right hanging type main body 2 continues to rise, the pressing device 7 pushes the upper side D of the rectangular wrapping cloth and the hanging type lifting device 4 causes the left and right hanging type main body 2 to move.
By the force of rising, the central portion of the upper side D of the rectangular wrapping cloth covered on the left and right hanging type main body is gradually pushed downward, and is discharged from the air discharge port 5 formed in the left and right hanging type main body. The pressurized air loosens the part that hangs down from the left and right hanging type books, and the corners of the upper side of the square-shaped wrapping cloth pressed against the upper ends of the ascending pieces 102, 102 of the left and right hanging type main body with relatively little resistance. E and E come to be located.

Press the rectangular wrapping on the line connecting the
As a result, when the hanging portion of the rectangular wrapping cloth passes over the resistor 12, the rounded edge on the side of the hanging portion faces the operator side by the curling action, so that the rectangular wrapping cloth can be turned inside out.
When the rounded edge on the side of the hanging portion is in a normal state, it moves without being turned over.

On the other hand, during this time, the rotary circulation device 11 continues to move in the inner direction of the base, and the rectangular wrapping which is turned inside out as described above has both corners E, E of the upper side D gripped to the left and right respectively. By being gripped by the holding devices 8 and 8, the upper side D side moves to the back side, and the hanging portion contacts the rotating device 16 provided above the regulation plate 14. Then, after a lapse of a certain time, the rotary circulation device 11 is operated and the rotary device 1
As 6 rotates, the hanging portion of the rectangular wrapping material passes over the rotating device 16 and is transferred into the suction chamber 15 provided on the inner side of the regulation plate 14.

When the hanging portion of the rectangular wrapping cloth is transferred to the suction chamber 15, the air suction device 17 operates to pull the hanging portion downward, and the one gripped by each of the left and right gripping devices 8, 8. Tension is generated between the upper side D of the shape wrapping cloth and the edges of the left and right sides and the lower side of the rectangular shape wrapping cloth that are hung vertically are shaped linearly. During this time, the rotary circulation device 11 continues to move in the back direction of the base, and the holding device 18 waiting on the back side of the base holds the upper side D of the rectangular wrapping cloth, and after the holding, the left and right sides are held. The gripping devices 8, 8 release the gripping operation of the upper side corners E, E of the rectangular wrapping cloth and deliver the upper side D to the holding device 18.

When the transfer is completed, the transfer device 19 transfers the rectangular wrapping cloth A to the next step while the hanging portion is pulled into the suction chamber 15, while the rotary circulation device 11 holds the rectangular wrapping cloth A on each side. The devices 8 and 8 wrap around upward from the back side of the base and return to the original standby position before the working side. The left and right gripping devices 8, 8 are attached to the rotary circulation device 11 at appropriate positions at appropriate intervals in the traveling direction, and after the rectangular wrapping material A is received by the holding device 18, the transfer device 19 is provided. During the process of transferring to the next process side, if the other left and right gripping devices 8 and 8 stand by at the positions where the upper corners of the next rectangular wrapping can be gripped, the work can be performed continuously. .
At this time, in the rectangular wrapping material to be processed next, both corners of the upper side are exposed by a hanging mold body different from the hanging mold body that was initially hung. The left and right gripping devices 8, 8 that are on standby are gripped.

By repeating the above-mentioned operation, it is possible to successively turn over the rectangular wrapping cloth A.
