And a driving means for adjusting the position of the transfer conveyor in the width direction is connected via a control device.

[0006]

According to the present invention, the laminated sheet material is unwound together with the liner from an unwinding roll onto a transfer conveyor, and the liner is peeled off from the laminated sheet material. The transfer material is conveyed to a bonding position by a transfer conveyor, the width of the bonded sheet material is detected by a width detection sensor immediately before bonding, and the transfer conveyor is moved in the width direction based on a width detection signal from the width detection sensor. After being moved to control the position of the laminated sheet material in the width direction, the laminated sheet material is laminated on the surface of the laminated sheet material conveyed on the laminating conveyor. The width of the laminated sheet material to be laminated to the laminated sheet material conveyed on the laminating conveyor can be accurately detected to improve lamination accuracy. Than it is.
