PURPOSE:To prevent surely slippage of liner materials in the liner material sticking process, by fixing liner materials to sheet materials temporarily by thermal welding previously. CONSTITUTION:Liner material 2a consisting of nonwoven fabric of synthetic resin is positioned and put on sheet material 1a consisting of synthetic resin, and liner material 2a is welded thermally near the forward end side of sheet material 1a in the transfer direction partially by temporary fixing mechanism 13. The production device is provided with welding mechanism 26 which welds liner material 2a, which is fixed temporarily, to sheet material 1a with patterns A and B matched to punching hole kinds by thermal welding, welding mechanism 37 which welds thermally liner material 2a to the whole of sheet material 1a with many parallel line patterns C, and the carrying means which transfers sheet material 1a to respective mechanisms successively. |
