A method for producing a backsheet for absorbent sanitary articles provided with hook-and-loop fasteners, comprising the steps of: advancing a continuous web of fibrous material without support at a first speed; cutting the continuous web of fibrous material without support in a transverse direction so as to form sections of fibrous material; accelerating the sections of fibrous material at a second speed greater than said first speed; welding said sections of fibrous material spaced apart at constant intervals onto a continuous nonwoven support web advancing at said second speed, so as to convert said sections of fibrous material into frontal tapes of loop-material for hook-and-loop fasteners; and fixing a continuous impermeable film to said continuous nonwoven support web with said frontal tapes of loop-material, so as to form a continuous backsheet web provided with frontal tapes of loop-material spaced apart at constant intervals.
