is rotated clockwise and returned to its original position by the operation of the rotation mode 37. In addition,
The guide roller cylinder 65 is connected to the take-up reel R.
After the winding of the material W is completed, the shortening operation is performed, whereby the guide roller 67 is returned to its original position.

Further, on the standby side, the take-up reel R is set in the same manner as described above, and the take-up reel R
The starting end of the interlayer paper P is wound around the paper sheet P in preparation for the next winding.

When the winding of the material W onto the winding reel R is completed, the winding motor 15 is stopped, and then the actuating means 30 of the cutter device 28 is activated to cut the material W. The interlayer paper P is automatically cut by the operation of the scissors device 24.

After both cuts, the turntable 12 is activated, the standby take-up reel R is moved to the take-up side, and the above-described take-up operation is repeated. On the other hand, the take-up reel (finished product reel) R on which the material W has been wound is transported to the finished product storage section 40 in the following manner. That is, from the state shown in FIG. 1, the carrier 50 is moved to the right via the moving means, the carrier head 51 is raised via the elevating means, and the support pins 55, 55 of the reel receiver 54 are moved to the right. It faces support holes R4, R4 of the take-up reel R supported by the reel flange 16 (see FIG. 13). Furthermore, at this time,
The support pins 55, 55 of the reel receiver 54 are opposed to the support holes R4, R4 of the take-up reel R through which the support pins 18, 18 of the reel flange 16 are not inserted.

Next, the reel receiver 54 is moved backward by extending the reel receiver cylinder 52 in the same manner as described above, and the reel receiver 54 and the support pins 55, 55 are fitted into the support holes R4, R4 of the take-up reel R. The take-up reel R is supported by the reel receiver 54 as the reel receiver 54 is moved forward and returned to its original state by the shortening operation of the reel receiver cylinder 52. Note that in order to actively carry out the take-up reel R to the reel receiver 54,
A means for pushing out the take-up reel R to the reel receiver 54, for example, a pushing cylinder is connected to the reel flange 1.

Then, the reel receiving cylinder 52 is operated to extend, the reel receiving cylinder 54 is moved backward, and the take-up reel R is carried to the frontmost side of the finished product storage section 40. Thereafter, the reel receiver 54 is moved forward and returned to its original state by the shortening operation of the reel receiving cylinder 52, and the carrier 50 and carrier head 51 are returned to their original states via the moving means or the elevating means. Note that this return operation is omitted,
Following the loading of the take-up reel R into the finished product storage section 40, the operation for setting the next take-up reel R may proceed directly.

Thereafter, the take-up reel R is set in the same manner as described above, and the starting end of the interlayer paper P is wound around the take-up reel R in preparation for the next winding. Note that at this time, the interlayer paper reel P is also replaced with a new one.

In addition, when unwinding the material W from the take-up reel R that has taken up the material W, the terminal end of the material W (corresponding to the starting end at the time of winding), as the interlaminar paper P is unwinded, It can be easily removed from the core R1 of the take-up reel R. In addition, the terminal end of the interlayer paper P during unwinding of the material W (corresponding to the starting end during winding) is also the adhesive surface T1 of the winding core R1 of the winding reel R.

An adhesive may be applied to the winding core R1. Further, in order to prevent the take-up reel R attached to the reel flange 16 from falling off, it is preferable to provide an appropriate reel holding means for holding the take-up reel R only during winding.

(Effects of the Invention) That is, the gist of the present invention is the configuration described in the column of "Means for Solving the Problems" mentioned above, and the material is wound on the take-up reel on the take-up side of the turntable. While the material is being wound, the take-up reel, interlayer paper reel and interlayer paper are replaced on the standby side of the turntable, and when the winding of the material is completed, the turntable is rotated. Therefore, the take-up reel and interlayer paper reel on the standby side are set to the winding position in a short time and the next winding operation is started, so the time required to replace the take-up reel is significantly reduced compared to the conventional method. As a result, the time required for the press to stop operating can be shortened, or the press can continue operating without stopping, which has the effect of improving productivity. Furthermore, since the breakage of the interlayer paper during winding of the material is eliminated, productivity is further improved.
