- the length of the U-shaped retraction portion of the web P 2 drawn into the suction casing 42 of b is maintained within a predetermined range. Therefore, the web P2 is smoothly fed from the standby roll R2 similarly to the web P1, and the web P2 does not require much tension in this feeding.
- the sending speed of the web P2 on the standby route increases, and when the sending speed matches the sending speed of the web P1 determined by the rotation speed of the main feed roller 38, the speed sensor 10 A value of 0 sends a signal to the controller 62 indicating that the sending speed of the web P2 matches the sending speed of the web P1.
- the controller 62 contracts the connection cylinder 76 of the web connection section 70 and rotates the swing lever 74 clockwise. Therefore, the connecting roller 72 moves toward the receiving roller 84, and the rollers 72, 84 are connected to the webs P1, P2 with the double-sided adhesive tape T interposed therebetween. Hold P2.
- the swing lever 74 is rotated in the reverse direction to return to the original position, and the connection roller 72 is separated from the receiving port roller 84.
- the tension lever 92 is also rotated upward and returns to the original posture, and is engaged with the stopper 94.
- the controller 62 stops the rotation of the drive motor 22a and the sub-feed roller 66. Further, the drive motor 22 a is rotated in the reverse direction, and the web F pulled out from the mouth R 1 is wound around the mouth R 1.
- the controller 62 receives the detection signal from the pressure sensor Then, the drive motor 22b, that is, the rotation speed of the roll R2 that is currently in use is similarly controlled.
- the above-mentioned buffer device 40a is retracted from the use path from which the web P1 was sent out, and the controller 62 looks at the roll mount 4 through the above-described reversing motor 6 in FIG. Flip 180 ° clockwise. Therefore, the positions of the roll R2 and the roll R1 are interchanged.
- the buffer device 40b moves in the moving direction of the roll R2 in conjunction with the movement of the roll R2, and stops at a position above the buffer device 40a.
- Such movement of the buffer device 4Ob can move the standby route of the web P2, that is, the use route, while maintaining stable delivery of the web P2.
- the web P2 from the buffer device 40b is conducted to the main feed roller 38 via the guide roller 30 and the connection roller 72 in the same manner as the web P1 before the roll change. It is.
- the buffer device 40a since the buffer device 40a is in a retracted state, the web P2 does not interfere with the buffer device 40a.
- the buffer device 40a In conjunction with the movement of the buffer device 40b described above, the buffer device 40a is also moved in the moving direction of the roll R1 in conjunction with the movement of the roll R1, and the buffer device 4Ob is moved. Stop above the position where it was previously located.
- the used port R1 is removed from the spindle 10a, and a new web roll is attached to the spindle 10a as a standby port.
- the web of the new standby roller is drawn out by passing between the suction casing 42 of the buffer device 40a and the pusher 57, and then receiving rollers 84, reversing rollers 86,8. It is guided to the sub-feed port 66 through the guide roller 8 and the guide roller 90.
- the receiving roller 84 and the reversing roller 86 are in the retracted state, similarly to the buffer device 40a, the web is drawn from the new standby port, and the webs P2 and 1000 being sent out are changed. It can be done easily without negotiation.
- the buffer device 40a, the receiving roller 84 and the reversing roller 86 are returned to their original positions.
- the new web guided from the standby roll is opposed between the receiving roller 84 and the reversing roller 86 in a state close to the web P2 being fed.
- the pusher 57 inserts a new web into the guide groove, and is directed toward the suction casing 42 of the buffer device 40a. And extrude.
- the suction casing 42 automatically draws in a new web from its open end, and the new web enters a standby state similar to the state shown in FIG.
- the present invention is not limited to the above embodiment, and various modifications are possible.
- the controller 62 transmits the web P 2 based on the rotation speed signal from the sub feed motor 68. Can be detected, and the speed sensor 100 described above becomes unnecessary.
- the web connection section 70 is merely an example, and is not limited to the configuration shown in FIG.
- the reservoir device 21 is not used when the rolls are switched. However, in a situation where the running speed of the web on the manufacturing machine 1 side is too high, the reservoir device 21 is not used. Can also be used.
- the connection between the web P1 and the web P2 in the web connection section 3 may become unstable.
- the rotation speed of the pulling roller 23 and the main feed roller 38 of the reservoir device 21 is increased from the rotation speed in the steady operation, and the reservoir 2 of the reservoir device 2 1 A web P 1 is stored in 1 R for a predetermined length.
