It is mainly composed of two feeding rollers 45, 46 forming a pair, and at least one of these feeding rollers 45, 46 is actively rotated by a rotating means, for example, a motor, and the motor is rotated by a controlling means (for example, encoder). That is, when starting to wind the material W onto the take-up reel 12, this motor feeds out the leading end of the material W up to the core 13 of the take-up reel 12. Further, while the material W is being wound up by the winding device 12, each of the delivery rollers 45 and 46 is in a free state due to the motor being stopped, and is rotated to follow the movement of the material W being wound up.

In addition, a rotation shaft 4 of a suitable rotation means is provided in the center of the machine base 10.

Until the adhesion to the winding core 13 is completed, the guide receiver 48 is rotated counterclockwise from the state shown in FIG. 14.14, and the guide surface 48a is set at a guide position that is substantially on the same line as the travel path of the material W (see FIG. 5).

Then, the winding shaft 11 is actively rotated to wind up the interlayer paper P on the winding reel 12, and the starting end WE of the material W is sequentially fed (feeded out) by the operation of the motor of the feeding device 32. The starting end WE of the same material W is guided by the guide surface 48a of the guide receiver 48, and finally the take-up reel 1
It intervenes between the winding core 13 of No. 2 and the winding side of the interlaminar paper P, and is sandwiched between the superposition of the interlaminar paper P and wound onto the winding reel 12 (see the two points in Fig. 5). (See dashed line).

Thereafter, the operation of the motor of the feeding device 32 is stopped, each feeding roller 45, 46 is rotated following the movement of the material W to be wound up, and the guide receiver 48 is moved clockwise from the state shown in FIG. By being rotated, it is returned to its original state as shown in FIG.

In this state, the rotation of the take-up reel 12 causes
The material W is wound together with the interlayer paper P onto the same take-up reel 12. When the winding of the material W is completed, the actuating means 18 of the cutter device 16 is actuated to

The take-up reel 12 on which the material W has been wound is replaced with an empty take-up reel. In addition, to replace the take-up reel 12,
It can be done manually or automatically.

Thereafter, by repeating the above, the empty take-up reel 12
The material W is wound into the winding machine.

In addition, when unwinding the material W from the take-up reel 12 that has wound the material W, the terminal end of the material W (starting end WE at the time of winding)
Applies to. ) can be easily removed from the core 13 of the take-up reel 12 as the interlayer paper P is unwound. Furthermore, the terminal end of the interlayer paper P (corresponding to the starting end PE during winding) during unwinding of the material W is also easily peeled off from the adhesive surface 15a of the winding core 13 of the winding reel 12.

In this example, the adhesive tape 15 is attached to the core 13 of the take-up reel 12 to form the adhesive surface 15a, but instead of this, an adhesive is applied to the core 13 of the first take-up reel 12. Good too.
