Disclosed is a nonwoven loop sheet for disposable diapers, miscellaneous goods, or clothes. The nonwoven loop sheet fastens on a hook tape of a hook and loop fastening tape. Loop protrusions having a low fiber density are formed on a surface of a low-priced nonwoven fabric to provide fastening strength to the hook tape. The nonwoven fabric, which is movably supported by a forming roll, is pressed using a heated pin punch roll to form the loop protrusions having a low fiber density on the surface of the nonwoven fabric. To commercially produce the nonwoven loop sheet, the pin punch roll, which heats and presses the nonwoven fabric and forms the loop protrusions on the surface of the nonwoven fabric, and the forming roll, which comes into close contact with the pin punch roll to movably support the nonwoven fabric to form the loop protrusions on the nonwoven fabric, are provided. In the production of the nonwoven loop sheet, the forming roll and the heated pin punch roll rotate while they come into close contact with each other. The nonwoven fabric is provided between the rotating pin punch and forming rolls so as to movably support the nonwoven fabric by the forming roll to form the loop protrusions having the low fiber density on the surface of the nonwoven fabric. Thereby, desirable fastening strength of the nonwoven fabric to the hook tape is assured. Fastening strength of the loop sheet to the hook tape is stably maintained, stable fastening is assured even though fastening is repeated a few times, and little fluff is formed during fastening and separation operations.
