Is a large carpet base material. Therefore, it is not necessary to provide a through hole as in the conventional case. Furthermore, since the back surface of the seat is alternately uneven, it is a carpet base material having good cushioning properties.

る事ができる。In this carpet base material, a laminated sheet is pressed from both sides by two roll-shaped pressing dies provided with a large number of projecting pieces so that the projecting pieces are staggered, and then the sheet is pressed alternately. Since the intermediate portion of the uneven fibrous sheet is cut into a flat shape, this fibrous sheet is alternately attached to both carpet base materials, and two single sheets are laminated. The base material for carpet can be taken, the production amount is doubled, and the production efficiency can be improved.
