A vacuum device 18 is provided on the back side of the belt 8, and the fibers 19 formed by the combing roll 4 unraveling the sheet-like objects 3, 3'to be disassembled are sucked and deposited on the belt 8 by the vacuum means. The fibrous web 7 and the second fibrous web 11 can be formed. The first fibrous web 7 moves together with the mesh belt 8 to reach the magnetic material distribution device 9, and the non-magnetized magnetic material 10 is evenly distributed on the first fiber web 7 by the distribution device 9. It As an example of the magnetic material 10,
Ferrite fine powder is integrally attached to a thermoplastic synthetic resin film in a coated state and cut into strips of appropriate size, for example, a commercially available magnetic tape coated with ferrite fine powder on one side of a polyester film. Strips cut to a length of 1 to 20 mm, preferably 3 to 5 mm can be used. As such strips, in the state of the magnetic tape before cutting, 5 to 200 in the longitudinal direction of the tape.
%, Preferably 10 to 100% is added to the drawing, and the pipe-shaped material having the ferrite coating surface on the outside is thermally deformed, and then cut and used. By deforming the strips in this manner, the entire outer peripheral surface of the pipe-shaped material can be a coated surface of the fine ferrite powder, which is convenient. The spraying device 9 can spray the magnetic material 10 only on a desired portion of the first fiber web 7 by appropriately selecting the size, the installation position and other conditions. The second fiber web 11 is formed by the second defibrating unit 2 on the first fiber web 7 so as to sandwich the non-magnetized magnetic material 10 thus dispersed. As a reference, the defibrated sheet-like materials 3 and 3'for forming the first and second fibrous webs 7 and 11 do not necessarily have to be the same.

The fibers are evenly interposed and are fused and fixed to the fibers in the nonwoven fabric by heating under pressure to be stably fixed. Therefore, it is possible to prevent the magnetic material from inadvertently detaching from the nonwoven fabric during handling or processing of the nonwoven fabric.
Further, since the magnetic material is fixed inside the non-woven fabric in the form of strips of the film, the inherent properties such as flexibility, processability and lightness are not impaired.
